Description

  The present invention relates generally to the field of breathing systems for ventilating patients, comprising a device with a display for providing a graphical user interface (GUI).

  During a patient's mechanical ventilation, the clinician often attempts to maintain a specific ventilation strategy for treatment that is considered particularly advantageous for the patient undergoing mechanical ventilation.

  However, so far, ongoing ventilation has been carried out in a way that is clear and understandable to the clinician when it comes to the most important point how current patient ventilation relates to the chosen ventilation plan. There is no flexible tool that can be used to know the status.

  Such tools are particularly desirable to be adaptable to the ongoing ventilation status of the patient in the ventilation itself. Also, this may be desirable if the tool provides the clinician with feedback that can be understood remotely from the breathing apparatus. For example, it may be desirable to quickly present a clinical user an overview of the current ventilation plan. Each ventilation plan has goals. Rapid identification of adherence to this goal of on-going ventilation for clinical users is desirable, and allows for quicker clinical decisions related to ventilation planning. For example, patients in isolation or undergoing x-rays can not be approached by clinicians with undue burden.

  Thus, such a tool would be advantageous if it provided the clinician with the current status of ventilation for the desired plan, even though it is far from the respirator.

  For example, it would be advantageous if this tool could be provided without the patient being connected to a breathing apparatus, for example in simulated ventilation, for clinician education. This is achieved, for example, in the animated display of a pair of lungs moving in synchronization with the breathing pattern, as it is only possible to visualize the ongoing ventilation by animating the inspiratory and expiratory phases, which No information is available from animated displays related to clinical status. If the ventilation plan is changed by the clinical user, there is no change in these animated displays. Furthermore, these animated displays are the same for different patients and do not take into account their impact on specific patient personality and ventilation plans.

U.S. Pat. No. 5,76,9082 Japanese Patent Laid-Open No. 2000-70370

  Thus, there is a need for such a tool implemented in a system comprising a breathing apparatus that can perform ventilation and perform a desired ventilation plan based on its adjustment. And, clinical decisions relating to the treatment of patients undergoing mechanical ventilation may be facilitated. The treatment of patients undergoing mechanical ventilation may be improved. The cost of treatment is potentially reduced by more effective treatment that can be done when considering how current patient ventilation is related to the chosen plan in such a clear and understandable way obtain.

  Therefore, it would be advantageous to have an improved respiratory system to provide clear and easily understood feedback on the desired outcome of an ongoing ventilation plan.

  This need is met by the solution according to the present disclosure.

  Accordingly, embodiments of the present disclosure are preferably those in the art, such as those set forth above, alone or in combination, by realizing systems, methods, etc. according to the appended claims. It seeks to mitigate, alleviate or eliminate one or more defects, disadvantages or problems.

According to one aspect of the present disclosure, a system is provided. The system comprises a breathing apparatus, a display unit and a processing unit operably connected to the display unit, the processing unit being configured to present graphical visualization on the display unit Graphic visualization is
A target indication of at least one ventilation-related parameter of the ventilation plan for the patient undergoing mechanical ventilation with the device, preferably a user input of the operator of the respiratory device, etc., a measure of the patient's physiological or anatomical structure Or a target indication based on a default value stored in a memory unit operatively connected to the processing unit;
-Including a combination of at least one ventilation-related parameter with regard to the target indication with a round trip animation display.

  This allows the clinician to know in a clear and understandable manner how current patient ventilation can be related to the chosen plan.

  The ventilation plan may include one or more ventilation-related parameters that are desirable for obtaining a particular value for a particular patient, which may be considered a particular value for treatment of the patient. The ventilation related parameter may be the desired ventilation per patient weight, ie tidal volume per kg body weight [mL / kg standard body weight] and / or a specific airway pressure. Other ventilation-related parameters of such a ventilation plan are, for example, inspiratory oxygen concentration, positive end expiratory pressure (PEEP), which is desirable to carry out the ventilation plan by obtaining specific values during ventilation. is there.

Additional ventilation parameters that are desired to obtain specific values for specific patients within the desired ventilation plan are based on inspiratory O ₂ (FiO ₂ ) and PEEP. The ratio of FiO ₂ to PEEP may be clinical parameters suitable for the desired ventilation plan. Suitable values for this ratio may be selected by the clinician or from predetermined values. The default value may, for example, be based solely on the input of the target FiO ₂ or the target PEEP, after which the processing unit automatically calculates the desired ratio. Alternatively, or in addition, two parameters may be present values and individual goals, graphical visualizations aggregate including multiple graphic visualizations as revealed in the detailed description. Can be given respectively.

  The patient's height and weight inputs may be predetermined target indication values, eg, Vt for a particular patient's height and weight.

  The graphical visualization of the present disclosure is a visualization of a ventilation plan. It should be noted that visualization is particularly advantageous in many clinical applications.

  For example, ventilation plans can be particularly large when affected by ventilation parameters that are not directly linked to one another.

  As an example, in the pressure support mode or the pressure-controlled mode of the breathing apparatus, adjustment of the ventilation parameters of the breathing apparatus when a ventilation plan related to tidal volume is desired as in the several examples described below Is related only to the ventilation pressure, and it is mentioned that adjustment of the amount delivered to the patient is not possible. Depending on the patient's anatomy, tubing used, etc., the result is a tidal volume delivered to the patient. Graphic visualization as disclosed herein provides advantageous direct feedback to the clinical user of the amount to be delivered to the patient regarding the desired amount to be delivered. Deviation can be corrected quickly by adjusting the ventilation parameters different from the desired planned ventilation parameters. In this example, the target pressure is clinical, so that the desired target ventilation per patient weight of the ventilation plan, ie tidal volume per kg body weight [mL / kg standard body weight] is obtained after adjustment has been made. It may be adjusted appropriately by the user. It should be noted that any target amount can not be set directly by the clinical user to operate the breathing apparatus in pressure support mode or pressure mode.

  Another example in which the graphical visualization of the present disclosure results in particularly large values is the metered breathing mode. Here, the clinical user can adjust volume-related goals in the respiratory device, such as the minute volume of respiratory gas delivered to the patient. However, as part of a ventilation plan, it may be desirable to keep the patient pressure within a certain range, such as below a certain threshold. Because pressure is the result of volume relationship adjustment and the target for pressure can not be entered in these ventilation modes, the graphical visualization of the present disclosure is a particularly advantageous tool for clinical users. Again, deviations from the target pressure of the ventilation plan can be quickly corrected by adjusting the ventilation parameters different from the desired plan ventilation parameters. In this example, the target minute output may be adjusted by the clinical user as appropriate to obtain the desired target pressure of the ventilation plan.

  Another example where the graphical visualization of the present disclosure is of particularly high value is a patient breathing spontaneously in a volume support breathing mode. In this mode, the goal of the ventilation plan may be to provide the patient with the desired minute volume. Again, deviations from the target minute volume of such ventilation plan can be quickly corrected by adjusting the ventilation parameters different from the desired plan ventilation parameters. In this example, the oxygen content of the inspiratory respiratory gas may be increased, the breathing mode may be changed to a mechanical (non-spontaneous) ventilation mode or the like. The clinical user is provided with a useful tool that assists in making clinical decisions related to the treatment of the patient such that the treatment is performed by following the desired ventilation plan.

  The round-trip animation of at least one ventilation-related parameter with respect to the target indication described in the specification for aspects of the present disclosure, exemplified by the following detailed description, may take various forms. This represents the current value of the parameter. At simulation time, if the patient is not connected, this may be its simulated value.

  One aspect is animation presentation in a continuous form. For example, in the example with a bar graph, the movement of the front of the bar may be continuous. Continuous movement may be synchronized with the breathing cycle. This movement may be, for example, forward (eg, in the case of a bar) or outward (eg, in the case of a ball) during inspiration, and vice versa during exhalation, reversing at the value of the apex. The continuous movement can be performed in real time, for example based on the measured value if the value can be provided continuously. If the values can only be provided intermittently, averaging can be done to provide a continuous form of animation. Movement is relative to goal indication.

  Alternatively, the movement of the ventilation plan indicator may be discontinuous, such as stepwise. This movement may occur when the values for the parameters are updated or provided intermittently. Therefore, animation display can be performed stepwise.

  The animation display moves towards the closing price of the round trip animation display in all cases. It may not be important how the animation display reaches this closing price (or the maximum price). However, the motion can provide useful information to the clinical user, such as information of its acceleration. The closing price brings very useful information to the clinical user when it shows a relationship with the ventilation plan's target value.

According to another aspect of the present disclosure, a decision support system is provided. The decision support system comprises a breathing apparatus, a display unit, and a processing unit operatively connected to the display unit. The processing unit is configured to present the graphical visualization on the display unit. This graphic visualization is
A target indication of at least one ventilation-related parameter of the ventilation plan for the patient undergoing mechanical ventilation with the device, preferably a user input of the operator of the respiratory device, etc., a measure of the patient's physiological or anatomical structure Or a target indication based on a default value stored in a memory unit operatively connected to the processing unit;
-Including a combination of at least one ventilation-related parameter with regard to the target indication with a round trip animation display.

  In addition, graphical visualization facilitates the operator to make decisions related to adjusting the ventilation settings of the breathing apparatus to accomplish the ventilation plan.

According to a further aspect of the present disclosure, there is provided a computer readable recording medium embodying a computer program for processing by a processing unit. The processing unit comprises a breathing system comprising a breathing apparatus and a display unit. The processing unit is operatively connected to the display unit, and the processing unit is configured to present the graphical visualization on the display unit. The computer program includes code segments for presenting graphic visualization, which is
A target indication of at least one ventilation-related parameter of the ventilation plan for the patient undergoing mechanical ventilation with the device, preferably a user input of the operator of the respiratory device, etc., a measure of the patient's physiological or anatomical structure Or a target indication based on a default value stored in a memory unit operatively connected to the processing unit;
-Including a combination of at least one ventilation-related parameter with regard to the target indication with a round trip animation display.

  According to a further aspect of the present disclosure, a graphical user interface for a breathing system is provided. The system comprises a breathing apparatus, a display unit, and a processing unit operatively connected to the display unit. The processing unit is configured to present the graphical visualization on the display unit. The graphical visualization then includes a combination of a target indication of at least one ventilation-related parameter of the ventilation plan for the patient undergoing mechanical ventilation with the device and a back-to-back animated representation of the at least one ventilation-related parameter related to the target indication.

  The target indication is based, for example, on the input of the user, such as the operator of the breathing apparatus.

  Alternatively or additionally, the target indication may be a default value stored in a memory unit operatively connected to the processing unit.

  Alternatively, or additionally, the goal indication is based on measurements of the patient's physiological or anatomical structure. The measurements include, for example, blood gas values, such as the vagus nerve, which stimulate the patient's diaphragm, measured lung time constants, brain signals, nerve signals.

  Alternatively or additionally, the user input may be another input, such as a personal communication device, communicating with the breathing apparatus and / or the processing unit, eg via a wired or wireless link known in the art. It can be done by the device. In this way, the system can inform the clinician in a clear and understandable manner how current patient ventilation is related to the selected ventilation plan.

  Further embodiments of the invention are defined in the dependent claims of the appended claims, and the features for the second and subsequent aspects of the invention are as for the first aspect mutatis mutandis. It is.

  The target indication may be displayed at a first position on the screen, and the first position is fixed during animation display.

  The round trip animation display may be synchronized with the breathing cycle of the patient undergoing artificial respiration. Alternatively, the round trip animation display may be synchronized with ventilation related parameters as measured for a patient undergoing mechanical ventilation. The reciprocating animation display may be reciprocating from the start point to the end point with respect to the target instruction. This provides information indicating how the ventilation plan is performed using graphical visualizations in which the ventilation process is animated during ventilation. At the end of inspiratory and / or expiratory phase, the animation display stops at a level that can be related to the specified plan.

  The start point is variable with respect to the ventilation related parameters at the respiratory cycle start time and may be synchronized therewith. The end point is variable with respect to the ventilation related parameters at the end expiratory time of the breathing cycle and can be synchronized therewith. This provides a measure for ventilation planning without being limited to a reciprocating process that is directly synchronized to the respiratory cycle.

  The target indication may be updated at regular intervals during ventilation.

  This makes it possible, for example, to achieve a flexible ventilation plan that is adaptable to the patient's treatment progress.

  The graphical visualization may include a plurality of ventilation-related parameters in the combined goal indication and round trip animation display, each for different ventilation related parameters, and the combined goal indication and round trip animation display are adjacent to each other Presented in a form.

  This gives a comprehensive overview of a more complex ventilation plan.

  The first and second combined goal indication and round trip animation may be presented in different graphic layouts.

  This provides a comprehensive overview of the ventilation plan with subtle differences in detail and provides easy access to details related to the progress of the ventilation on the ventilation plan.

  The round trip animation display is the highest value of the ventilation related parameters, which is placed outside the range including the target indication or smaller than the second threshold larger than the first instruction threshold larger than the target instruction or smaller than the target instruction May include different layouts for

  This provides an indication that can be easily perceived if it exceeds, does not reach or is not the ventilation plan to be performed.

  Graphical visualization includes graphical appearance depending on the operating parameters of the respiratory system, including display of alarm boundaries, and maximum inspiratory pressure, positive end-expiratory pressure when crossing alarm boundaries, which is different from reciprocating animation display The graphical appearance of the display of additional metrics of ventilation related parameters such as (PEEP), mean airway pressure (Pmean), and plateau pressure (PPlat) may be included.

  Note that alarm boundaries are not ventilation plan goals. Therefore, alarm boundaries do not form the basis for goal indication and should not be confused with the latter.

  The system can be equipped with an additional animation display feature for the patient's ongoing ventilation.

  The processing unit of the system may be configured to receive input from the operator for selection of ventilation related parameters of the ventilation plan and / or adjustment of values for target indications within a predetermined range. The processing unit of the system is configured to receive the ventilation-related parameters as predetermined ventilation-related parameters and / or values for the target indication from predetermined values stored in the memory of the system accessible to the processing unit. obtain.

  This is to ensure the safety of operation when access to certain adjustments may be limited to some operators of the breathing system.

  The display unit may be incorporated into the respiratory device. This may be an independent display unit in communication with the breathing apparatus.

  This provides a flexible system with advantageous user acceptance.

  Graphic visualization may be implemented as a graphical decision support tool for the operator to achieve a ventilation plan.

  This allows easy identification when it is necessary to adjust the ventilation settings to achieve the desired ventilation plan.

  The present disclosure provides, for example, a tool that can be performed without connecting a patient to a breathing apparatus, for example in simulated ventilation. This tool is useful, for example, for clinician education, which allows the clinician to effectively determine and clinically follow a ventilation plan that is helpful for patient care.

  Specific embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention can be embodied in many different forms, and therefore should not be construed as limited to the several embodiments described herein, but rather, these embodiments The present disclosure is exhaustive and complete, and is realized so as to fully convey the scope of the present invention to those skilled in the art. The terms used in the detailed description of the embodiments shown in the accompanying drawings are not intended to limit the present invention. In the drawings, like numbers refer to like elements.

  FIGS. 1A, 1 B, and 1 C are schematic views of an example of a system of the present disclosure, including a first system 1, a second system 2, and a third system 3. The systems 1, 2, 3 comprise the configuration of a breathing apparatus 10, a display unit 30 and a processing unit 20 operatively connected to the display unit 30. The patient 40 is fluidly connected to the system for artificial respiration via the inspiratory line 11 and expiratory line 12. Processing unit 20 is configured to present graphical visualizations on display unit 30. Examples for such graphical visualization are shown in FIGS. 2-9 and 12 and are described in more detail below.

  Graphic visualization includes the combination of at least one goal indication for the ventilation plan and associated animation of at least one current ventilation-related parameter.

  The target indication is either user adjusted or based on a default value. The default value for the goal indication may alternatively or based on alternative data or an input source for that value, or in addition to operator input. Default values for goal indication may be provided, for example, from an accessible database. The default value may be based on patient data, for example based on the weight and height of the patient connected to the system's breathing apparatus. The default value may be included within the default range of values. The default value may be based on measurements of a patient connected to the respiratory device. The breathing apparatus can then provide a recommended value or range of values that the user can use to select a target value. All the aforementioned alternative values, alone or in combination, are included in the term "default" (value) to the target indication as used herein.

As an example for ventilation related parameters, IBW body weight V / kg, for example 4, 6, 8 ventilation related pressure parameters, ie PEEP, P-peak, within a specific range, for example 4-15 ml iVT / kg BW , The ratio of such parameters, such as PEEP / FiO ₂ , and indexes etc.

  In ventilator 10, the desired ventilation plan may be specified by the user, for example. The ventilation plan is, for example, tidal volume in units of mL / expected body weight of the patient receiving mechanical ventilation. Expected or standard weight may be entered directly by the clinician or calculated from the height and gender of the patient.

  During ventilation, it is shown how a ventilation plan is performed using graphic visualization where the ventilation process (eg, tidal ventilation) is animated. At the time of the end inspiration (or end expiration), the animation display stops at a level that can be related to the specified plan.

  This means that if a plan such as tidal volume per kg body weight at 6 mL / kg is used and the patient is ventilated at tidal volume per kg body weight less than 6 mL / kg, the visualization is It means that it does not reach the (fixed) graphic dividing line, which is a planned target indicator. If the ventilation provided is greater than the tidal volume per kg body weight of 6 mL / kg, the animation display passes through the graphic dividing line.

  The animation display preferably has the same pace as the respiration rate.

  The visualization may be provided as a circle, a sphere, a bar graph, a height above the horizon, eg a 3D object that zooms in and out.

  The graphical visualization of the present disclosure is only visualization. As such, the display unit 30 need not be touch sensitive. However, in some instances, the display 30 can be a touch screen that provides additional benefits in a suitable graphical user interface.

  An animation, an animation-based progress, or a reciprocating / oscillation movement is presented regarding the progress of the ventilation-related parameters over time. The round trip animation display may be synchronized with the breathing cycle of the patient undergoing artificial respiration. In particular, the reciprocating portion of the animation display can be paced with the respiration rate of the patient currently receiving artificial respiration. Alternatively, the reciprocation animation display may be synchronized with ventilation related parameters as measured for a patient undergoing mechanical ventilation, which may be different from the breathing cycle. The reciprocating animation display may be reciprocating from the start point to the end point with respect to the target instruction. This provides information indicating how the ventilation plan is performed using graphical visualizations in which the ventilation process is animated during ventilation. At the end of inspiratory and / or expiratory phase, the animation display stops at a level that can be related to the specified plan.

  The start point is variable with respect to the ventilation related parameters at the respiratory cycle start time and may be synchronized therewith. The end point is variable with respect to the ventilation related parameters at the end expiratory time of the breathing cycle and can be synchronized therewith. This provides a measure for ventilation planning without being limited to a reciprocating process that is directly synchronized to the respiratory cycle.

  The reciprocation animation display is located outside the range including the target indication, which is smaller than the second threshold larger than the first threshold larger than the target indication, or smaller than the second threshold smaller than the target indication. It may include different layouts for the highest value.

  This provides an indication that can be easily perceived if it exceeds, does not reach or is not the ventilation plan to be performed.

  For example, if the round trip animation display has a maximum / close value that is at a particular proximity to the target indication, the animation display can change the graphic layout to present an easily perceptible indication. This indication may inform the user of the patient's particular status regarding the plan. The status may include exceeding an acceptable limit of the ventilation plan or not reaching an acceptable limit of the ventilation plan within an acceptable limit of the ventilation plan. This allows for the advantageous current status of the ventilation provided with respect to the desired ventilation plan. The aforementioned acceptable limits may be limits within specific upper and lower threshold ranges for the target indication value. For example, the target threshold percentage may define a threshold / limit. An example is ± X% of target readings for too low / normal / too high. One example is ± 20%. The change in graphic layout may include a color change in graphic visualization to indicate / emphasize if the plan is exceeded, not received, or not.

  Graphical visualizations include graphical appearance depending on the operating parameters of the respiratory device, including display of alarm boundary values, maximum inspiratory pressure, positive end expiratory pressure (above positive alarm boundary value), which is different from reciprocating animation display, The graphical appearance of the display of additional metrics of ventilation related parameters such as PEEP), mean airway pressure (Pmean), and plateau pressure (PPlat) may be included.

  The processing unit of the system as described herein is configured to receive input from the operator for selection of ventilation related parameters of the ventilation plan and / or adjustment of values for target indications within a predetermined range. obtain. The processing unit of the system is configured to receive the ventilation-related parameters as predetermined ventilation-related parameters and / or values for the target indication from predetermined values stored in the memory of the system accessible to the processing unit. obtain.

  This is to ensure the safety of operation when access to certain adjustments may be limited to some operators of the breathing system. This can be provided or managed at the hospital level at the hospital. Access to a particular adjustment as a target indication of ventilation-related parameters, such as a desired ventilation plan, selection, or entry of values for selection may be restricted, for example, entry of an access code is required.

  User definable plans can be provided. Preferably, the planning goal is adjustable by the user within certain limits for input from a predefined range, for example 4-15 ml / kg (tidal volume / body weight).

  In this way, excessive values outside the predetermined range are avoided, which is advantageous from a safety point of view.

  The target indication may be displayed at a first position on the screen, and the first position is fixed during animation display.

  If the first position of the target indication is a fixed position, this may be, for example, a reference indication other than a stationary line, a reference line or a line.

  The target indication indicates the desired goal or outcome of the ventilation plan using the desired values based on the one or more ventilation related parameters.

  The target indication may be updated at regular intervals during ventilation. This makes it possible, for example, to achieve a flexible ventilation plan that is adaptable to the patient's treatment progress.

  The ventilation plan indicator is preferably updated at different intervals, such as every time breathing is complete. The processing unit may, for example, propose a value for the target indication, provide for user confirmation, or adjust automatically when patient status changes while ventilation is in progress. The goal indication may be moved to a new placement with respect to the placement of the previous value. Alternatively or additionally, the numerical values displayed for or at the goal indication may be updated.

  During ventilation, it is shown how a ventilation plan is performed using graphical visualizations in which a ventilation process (eg, periodic ventilation) is animated. At the time of the end inspiration (or end expiration), the animation display stops at a level that can be related to the specified plan.

  This graphical visualization should not be confused with the (user) adjusted ventilation parameters themselves. Graphic visualization places ventilation parameter values as obtained for the desired ventilation plan.

  This means that if a plan such as tidal volume per kg body weight at 6 mL / kg is used and the patient is ventilated at tidal volume per kg body weight less than 6 mL / kg, the visualization is , (Fixed) means that it does not reach the graphic dividing line. If the ventilation provided is greater than the tidal volume per kg body weight of 6 mL / kg, the animation display passes the graphic dividing line, ie the goal indicator 110.

  In the first system 1, the respirator 10, the display unit 30 and the processing unit 20 are integrated into a single unit. The memory unit 25 and the processing unit are integrated with the display 30, for example, in a single housing. However, the display may be connected to the housing of the pneumatic part (not shown separately) of the breathing apparatus.

  The display unit 30 may be incorporated into the breathing apparatus 10 as in the example of the first system 1. This may be an independent display unit in communication with the breathing apparatus. This provides a flexible system with advantageous user acceptance.

  Data for current ventilation related parameters may be transferred from the breathing apparatus to the remote display for graphical visualization. For example, the display may be a clinical monitoring system, such as a patient monitoring unit. The display may be, for example, a remote display located at a central nurse station. The display may be part of a portable device, such as a portable communication device. Applets on this device can present graphical visualizations based on data received from the breathing apparatus. The processing unit may be present at a suitable place in the system, ie for example in a portable unit comprising a breathing apparatus or display or display. The data is processed by the processing unit and transmitted to the display unit where it presents a graphical visualization. The data may include numerical data or graphic data related to the value of the ventilation related parameter. Although no processing unit is required on the display unit side to transmit graphic data to the display unit, it is assumed that numerical data has already been processed by the processing unit, and the graphic data is thereby described herein It is already in place for quick visualization of graphic visualizations.

  In the second system 2 the breathing apparatus 10 comprises a memory unit. The processing unit 20 is provided on the display unit 30 and is in communication with the breathing apparatus 10. The communication may be wireless. The processing unit receives data from the respirator, which has another processing unit in communication with the memory 25.

  Another example of a system (not shown) may not have a processing unit as described herein on the display unit 30 side.

  In the third system 3, the respiratory apparatus 10 comprises a processing unit 20 and a memory unit 25. The display unit 30 is in communication with the breathing apparatus 10. The communication may be wireless.

  Referring now to FIGS. 2-9, an example of graphical visualization to provide feedback of a ventilation plan related to ongoing ventilation is described. The breathing apparatus 10 is performing artificial respiration for the patient 40.

  In Figures 2 and 3, an example of a ventilation plan performance indicator is shown as a bar graph to visualize the ventilation plan with respect to the bar graph. Graphic visualization 100 is shown including bar graph 101. Graphic visualization 100 includes a target indication 110 of at least one ventilation-related parameter of a ventilation plan for a patient undergoing mechanical ventilation with the device. Additionally, the graphical visualization 100 includes an animated display 120 of at least one ventilation related parameter for the target indication 110. The movement of the bar is illustrated by the arrow 121. In embodiments with a bar chart, the (front) movement of the bar is referenced. The movement of the ventilation planning indicator is here in the form of a bar graph and may be continuous, such as a round trip. Alternatively, the movement of the ventilation plan indicator may be discontinuous, such as stepwise. The front, in this example, reciprocates from left to right and then back. The animation display maximum value 122 is reached at the return point or at the top of the bar graph portion of the animation display. The highest value is, in embodiments, the value of interest to the clinical user. The maximum value may be below the ventilation planning goal, just the ventilation planning goal, or above the ventilation planning goal. This information of the current maximum value of ventilation parameters related to the ventilation plan with respect to the goal of ventilation allows the clinical user to determine the ventilation continuation of the patient. Adjustments to the breathing apparatus settings can be made when needed.

  FIG. 2 is a schematic diagram illustrating a first example of graphic visualization in a first state, ie, when the maximum value 122 of the round trip animation display is smaller than the value of the target indication. Here, the portion of the round trip animation display of the bar graph has a vertex before reaching the goal indication 110.

  FIG. 3 is a schematic diagram showing a first example of graphic visualization in the second state, ie the highest value 122 of the round trip animation display exceeds the value of the target indication. Here, the portion of the round trip animation display of the bar graph has a vertex after reaching the goal indication 110.

  In FIGS. 4-9, an example of a ventilation plan performance indicator is illustrated as a curved object. Curved objects are illustrated as circular objects in these examples and visualize the ventilation plan with respect to the curved objects indicated by circles. A circle is just one example of a curved object. The object can also have other curved shapes, such as elliptical, sinusoidal, helical, etc.

  In FIGS. 4 and 5, further examples of ventilation plan performance indicators are shown as circular objects to visualize the ventilation plan with respect to the circle.

  A graphical visualization 200 is illustrated that includes a circular object having a center. The graphical visualization 200 includes the target indication 110, here in the form of a dotted circular line.

  Here, the ventilation planning goal instructions in the form of dotted lines do not necessarily have to be lines such as dotted lines, as long as they indicate ventilation planning goals for at least one ventilation related parameter of the ventilation plan for the patient receiving mechanical ventilation by the device. Thick lines, colors, shapes, etc. may be used for visual instructions. In addition, such colors, shapes, etc. may change when the current ventilation deviates from the set ventilation plan.

  Additionally, the graphical visualization 200 includes a back-to-back animated display 120 of at least one ventilation related parameter for the target indication 110. The reciprocating movement is illustrated by the arrow 121. The outer periphery of the black circle expands in a reciprocating manner from the center to the outer periphery in this example, and then returns toward the center. The animation display maximum value 122 is reached at the return point or at the apex of an exemplary black circle in the graph portion of the animation display 120. The corresponding return point of the animation display at the lowest value of the ventilation related parameter is illustrated by the inner ring 123. The values of the ventilation related parameters move in a reciprocating manner between the inner ring 123 and the maximum value 122. It should be noted that the lowest value as indicated by the circle 123 is not a constant value but is updated based on the current value provided by the breathing apparatus 10, together with the highest value 122 as indicated in the figure. .

  The animation display 120 may be in the form of a reciprocating 3D object. Examples of such 3D objects are spheres or bubbles.

  FIG. 4 is a schematic diagram illustrating this example of graphic visualization in the first state, ie, when the maximum value 122 of the round trip animation display is less than the value of the target indication 110. Here, the portion of the round-trip animation display of the circular object has a vertex before reaching the target indication 110. FIG. 5 is a schematic diagram showing this first example of graphic visualization in the second state, ie the highest value 122 of the round trip animation display exceeds the value of the target indication 110. Here, the portion of the round-trip animation representation of the circular object has vertices that exceed the goal indication 110, which in this illustrated example is after reaching the goal indication 110.

  The graphical visualization may include multiple / multiple ventilation related parameters in combined goal indication and round trip animation display, each for different ventilation related parameters, and the combined goal indication and round trip animation display may be: Presented adjacent to each other. This gives a comprehensive overview of a more complex ventilation plan. Such graphical visualizations include a number of ventilation-related parameters and target indications related to each of the latter, examples of which are described below with reference to FIGS. 6-9.

  Multiple visualizations provide a comprehensive overview of the ventilation plan. A large number of combined goal indications / animations for the same ventilation plan provide comprehensiveness.

  Multiple target indications for the same ventilation-related parameter may be displayed (e.g. one tidal volume per kg of 4 ml / kg in one row, 1 per kg of 6 ml / kg in another row) The tidal volume is displayed). A range of selectable (useful) values for the goal indication may be shown as a range indicator for the current goal indicator.

  Examples for many ventilation related parameters include: volume + target pressure, volume or pressure + Ppeak / (ml / kg).

  Further examples of ventilation plan performance indicators are illustrated in FIGS. 6 and 7. The graphical visualization includes a circular object 200 for visualizing a ventilation plan with respect to a circle, as described above with reference to FIGS. 4 and 5. Graphic visualization 200 includes a circular object having a center. Graphic visualization 200 includes a first goal indication 110. In the figure, the target indications correspond exactly to the ventilation related parameters visualized by the graphic visualization 200. The graphical visualization 200 will not be described in further detail, and reference is made to the sections above relating to FIGS. 4 and 5.

  The indicators shown in FIGS. 6 and 7 include a second graphical visualization 300. The second graphical visualization 300 is arranged to be concentric with the first graphical visualization 200. It can also be arranged to be non-concentric in another example. The second (or further) graphic visualization is arranged adjacent to the first (or other) graphic visualization 200 and constitutes a collection of multiple graphic visualizations for the same ventilation plan. Each graphic visualization relates to a specific ventilation-related parameter of the same ventilation plan and has its own target indication and a round trip animation display part.

  In aggregate 301, graphical visualization 300 is presented in the form of a bent bar graph. Although the target indication 310 is shown at the 6 o'clock position, it may be configured at other radial positions or sectors other than 6 o'clock. Additionally, the graphical visualization 300 includes a back-to-back animated representation 320 of ventilation-related parameters for the target indication 310. The reciprocating movement is illustrated by the double arrow 321. The bent bar graph has the front with the highest value 322.

  The front part, in this example, reciprocates within the circle from the start position, for example, from the top of the circle, to the end position, for example, the bottom point of the circle, and then turns back. This cycle is then repeated and the start and end values can be updated and changed continuously.

  FIG. 6 is a schematic diagram illustrating this example of the graphical visualization 300 when in the first state, ie, the highest value 322 of the round trip animation display 320 is less than the value of the target indication 310. Here, the portion of the round trip animation display of the bar graph has a vertex before reaching the goal indication 310.

  In one example, the first graphical visualization may refer to tidal volume [kg / kg] of body weight [mL / kg] and the second graphical visualization may refer to pressure.

  FIG. 7 is a schematic diagram illustrating an example of the graphical visualization 300 in the second state, ie, the maximum value 322 of the round trip animation display exceeds the value of the target indication. Here, the portion of the round trip animation display of the bar graph has the vertex after reaching the goal indication 310.

  The starting point of the reciprocating animation display may be at a position larger than the target indication 310. In FIG. 6, a visualization of ventilation less than the planned target level is shown. The animated representation of the first graphical visualization 200 visualizing periodic ventilation reaches the reference circle. However, the second graphical visualization 300 presenting pressure level visualizations terminates under the planned limits of the target indication 310. The respiration-respiration indication does not reach the fixed reference point, ie the target indication 310, eg the 6 o'clock position.

  In FIG. 7, the second graphical visualization 300 reaches and passes the baseline of the target indication 310. A visualization of pressure levels above planned limits is provided. The respiratory-respiratory indication goes beyond the fixed reference point, ie the target indication 310.

  The first and second combined goal indication and round trip animation may be presented in different graphic layouts.

  This provides a comprehensive overview of the ventilation plan with subtle differences in detail and provides easy access to details related to the progress of the ventilation on the ventilation plan.

  A comprehensive overview of the ventilation plan currently being followed provides subtle details that allow easy access to the details related to the ventilation plan.

  In addition, metrics may be displayed for target readings.

  Text may be presented to identify ventilation-related parameters of the ventilation plan to be followed.

  FIG. 8 is a schematic diagram of another example of such graphical visualization.

  As in the graphical visualization assembly 301 of FIGS. 6 and 7, the assembly 401 shown in FIG. 8 includes a number of graphical visualizations and some additional elements. Graphic visualization includes circular objects 200 for visualizing a ventilation plan with respect to a circle, as described above. Graphic visualization 200 includes a circular object having a center. Graphic visualization 200 includes a first goal indication 110. In the figure, the target indication is not reached by the ventilation related parameters visualized by the graphic visualization 200. The graphic visualization 200 will not be described in further detail, and reference is made to the sections above.

  The indicator shown in FIG. 8 includes a second graphical visualization 400. The second graphical visualization 400 is arranged to be concentric with the first graphical visualization 200. It can also be arranged to be non-concentric in another example. The second graphical visualization 400 is arranged adjacent to the first graphical visualization 200 and constitutes a collection of multiple graphical visualizations for the same ventilation plan. Each graphic visualization relates to a specific ventilation-related parameter of the same ventilation plan and has its own target indication and a round trip animation display part.

The graphical visualization 400 is presented in the form of a bent bar graph, such as the second graphical visualization 300 described with reference to FIGS. 6 and 7. Graphic visualization 400 is positioned to the right in FIG. 8 in this example. The target indication 410 is shown at the 6 o'clock position, but may be arranged at other radial positions or sectors other than the 6 o'clock position. In addition, graphical visualization 400 includes a back-to-back animated display 420 of ventilation-related parameters for target indication 410. The target indication 410 further comprises numerical values 415 to visualize the numerical value of the target indication for the particular ventilation related parameter of the graphical visualization 400. In this example, the value 415 is "30". The value 415 can alternatively also be displayed here with the correct unit, for example the unit [cmH ₂ O], here for pressure. The graphical visualization 400 reciprocates between the start value indicated by the start indication 421 and the highest value indicated by the highest value indication 422 at which the animation display is returned. The range between these start and maximum values is indicated by the bar 422. Bar 422 also includes a central indication.

  In the example, the second graphical visualization 400 refers to pressure. Text 430 is attached to the graphical visualization 400 so that the displayed parameter can be easily identified by the clinical user.

  The target indication 110 is shown in this example as a dotted circle and may further comprise one or more text and / or numeric objects 211. Text and / or numeric objects 211, such as the objects 212, 214 shown, further describe the current value of the target indication 110 of the current ventilation plan. This makes it easier for the clinical user to identify the current absolute value instead of the relative value to the ventilation planning goal only. The text, as with text 430, may facilitate identifying certain ventilation-related parameters, or selected values that are respectively predetermined values thereto, or input values for the latter. Text objects 214 provide such support for the user and may be particularly advantageous for decision support systems. In the example, a numerical value of 6 with a corresponding unit "ml / kg", ie tidal volume for a particular weight of a patient undergoing mechanical ventilation, is given to the ventilation planning goal. This is either a value selected by the user, based on measurements, given as a default value or the like, as described above.

  An indication line 213 to the target indication 110 provides the user with an easily identifiable link of the text object 213 to the target indication 213 without blocking the animation display 120.

  Similarly, text and / or numeric objects may be provided as metrics 212. In the example shown in FIG. 8, the metric is a VTBW for the term tidal volume (VT) per body weight (BW) that allows the user to identify the ventilation related parameters of this part of the ventilation plan. Including the abbreviation. The ventilation related parameter, here the current value of VTBW, is displayed as object 212. The current value of the example of FIG. 8 which is a still image of animation display is 4 ml / kg (tidal volume / body weight). The ventilation plan target "6 ml / kg" (text object 214 and corresponding target indication 110) is not currently reached because the current value "4 ml / kg" can not reach the target value. The clinical user can make appropriate decisions to adapt and update the current ventilation settings to obtain a ventilation plan.

  A system as described herein may comprise additional animated representations of the ongoing ventilation of the patient. Additional animation representations are advantageously integrated with or adjacent to the graphical visualization or a collection of graphical visualizations as described herein. An example of such a further animation display is, for example, the plurality of bubbles 500 as shown in FIG. The bubble 500 is presented to go back and forth in the illustrated example. In the example, the bubbles move back and forth about the center of the collection of graphical visualizations through the openings in the circular graphical visualization of ventilation related parameters. Further animated displays, such as bubble 500, and the movements shown with it, may be synchronized with inspiration and expiration, respectively, for each direction. Alternatively, or additionally, the additional animation may provide additional information, for example, information about leaks that occur during ventilation. A leak may be indicated by a bubble moving in one direction, such as outward in FIG. 8, without returning to the center. A leak indicating a bubble may move in a different direction than the bull 500 shown in FIG. In this way, a large number of ventilation-related parameters and the advantageously compacted visualization of the ventilation itself are configured without giving excessive information and burdening the clinical user.

  An animated representation of the patient's ongoing ventilation, such as bubble 500, is synchronized with the patient's current breathing cycle. It should be noted that the duration of the round trip animation display of ventilation related parameters may differ from the current breathing cycle, as the ventilation plan may be based on the measured parameters or parameters not synchronized with the current breathing cycle. Thus, a single collection of graphic visualizations has graphic visualizations that oscillate at different frequencies and additional information not otherwise readily available to make decisions when updating a treatment plan for a patient Can be provided to clinical users.

  An example for such a parameter that is asynchronous to the respiratory cycle is the electrical activity of the diaphragm. This may be advantageous in some modes of ventilation. One such mode of ventilation is, for example, neuromodulation assisted ventilation (NAVA), which is an Edi signal of the patient, that is, one mode of ventilation that provides assisted ventilation proportional to and synchronized with the electrical activity of the diaphragm. It is. Edi is measured, for example, using an esophageal measuring catheter. The ventilation planning goal may be based on the desired measured Eid signal. The Edi signal can also be related to tidal volume (VT). The ventilation plan goal may be a value for Edi / VT [μV / mL]. Edi / VT may be indicated in the manner as described herein with reference to tidal volume per kg body weight. This is an example for measurements of the patient's physiological or anatomical structure described above. Apart from the diaphragm EMG (Edi), other respiratory bioelectric and muscle signals synchronized with respiration can be considered for the same purpose.

  Another example for such a parameter that is asynchronous to the respiratory cycle is cardiac output.

  Another example for such a parameter that is asynchronous to the respiratory cycle is systolic respiratory variability, ie, arterial pressure variability related to respiration. Such parameters are actually measured by the systolic respiratory variability test (RSVT), as described in Azriel Perel US Pat. No. 5,769,082, which is incorporated herein in its entirety. It can be provided.

  Thus, measurements of the patient's physiological or anatomical structure may be provided for a ventilation plan from the measurement system that is external to the breathing apparatus or not directly related to the patient gas measurement.

  FIG. 9 is an example of a graphical user interface (GUI) that includes a graphical visualization collection 500 as shown in FIG. The aggregate 401 is shown as part of other graphic objects related to the patient's current ventilation. The metric object 650, 651, 652, 653 indicates the current value of the ventilation parameter. The measurement reference object 650 displays the inspiratory tidal volume VTi. The measurement reference object 651 displays the maximum airway pressure Ppeak. The metric object 652 displays the respiration rate RR. The measurement reference object 653 displays the breath tidal volume VTe. Curved object 652 shows, for example, a pressure time curve and a flow time curve.

  In the example of graphic visualization, producing a color change of at least part of the assembly described herein indicates / emphasizes whether the desired ventilation plan has been exceeded, as described above can do.

  If further planned parameters of ventilation in progress are displayed, the graphical visualization may comprise an adapted graphic layout, such as its color or shape. For example, if the alarm boundary value is exceeded, a different color may be used than if the alarm boundary value is not exceeded.

  Another aspect of ventilation planning, eg, maximum pressure, may be indicated for bar graphs or circles as described above. The ventilation plan indicator is preferably updated at different intervals, such as every time breathing is complete. Other pressures such as positive end expiratory pressure PEEP, mean pressure Pmean, and plateau pressure PPlat may be indicated.

  Graphic visualization may be implemented as a graphical decision support tool for the operator to achieve a ventilation plan.

  This allows easy identification when it is necessary to adjust the ventilation settings to achieve the desired ventilation plan.

  Where adjustments are made by the user, easily interpretable feedback may be provided for adjustment of the desired ventilation plan.
