In this example, the monitoring device 10 is connected to the electrocardiogram electrodes 30-1 to 30-N and to the ventilation bag 20. FIG. The electrocardiogram electrodes 30-1 to 30-N are an example of sensors (first sensors) for obtaining measurement information of heartbeat-derived parameters (for example, pulse rate, also referred to as first parameters). In this example, the monitoring device 10 includes electrocardiogram electrodes 30-1 to 30-3 (in the following description, 30-1 to 30-3 are simply referred to as 30 when not distinguished), a ventilation bag 20, and a wired Although connected, various information may be acquired from the electrocardiogram electrode 30 (first sensor) and the ventilation bag 20 by wireless communication connection.

The indicator 12 is, for example, an LED lamp, and flashes or lights up depending on whether or not the ventilation bag 20 is well ventilated and various vital signs are abnormal. Details of blinking and lighting by the indicator 12 will be described later with reference to FIG. 5 and the like.

The monitoring device 10 has connectors 13-1 and 13-2 for connecting with vital sign sensors (in the following description, when the connectors 13-1 and 13-2 are not distinguished, they are simply referred to as connector 13). do.).

Any number of connectors 13 may be provided in the monitoring device 10 .

An electrical configuration of the monitoring device 10 will be described with reference to FIG. FIG. 3 is a block diagram showing the electrical configuration of the monitoring device 10. As shown in FIG.

Monitoring device 10 includes display 11 , indicator 12 , connector 13 , operation interface 14 , speaker 15 , memory 16 , hard disk 17 , processor 18 and timer 19 . Note that the monitoring device 10 may include a wireless interface WF for wireless communication. The wireless interface WF is an interface for transmitting and receiving data to and from any other device, and enables data communication according to the wireless LAN standard, for example.

The connector 13 is an interface that connects with the electrocardiogram electrodes 30 and the ventilation bag 20 as described above. Connector 13 provides signals received from electrocardiogram electrodes 30 and ventilation bag 20 to processor 18 .

A user (mainly a medical worker such as a doctor or a nurse) operates the operation interface 14 to perform various inputs. The operation interface 14 is, for example, buttons, knobs, rotary selectors, keys, etc. provided on the housing of the monitoring device 10 . Note that the operation interface 14 may be integrated with the display 11 as described above (that is, it may be a touch display). Examples of the operation interface 14 include a monitoring start button and an alarm cancel button. Inputs through the operation interface 14 are input to the processor 18 .

The speaker 15 outputs various notification sounds such as an alarm. The speaker 15 notifies according to the control of the processor 18 .

The memory 16 is primary storage means that acts as a working area when the processor 18 executes programs. The hard disk 17 stores various programs (including system software and various application software) and data (pulse rate information, etc.). The hard disk 17 may be built in the monitoring device 10 or may be externally attached.

The processor 18 (controller) controls the operation of the monitoring device 10 . Specifically, the processor 18 performs measurement processing based on signals acquired from the ventilation bag 20 and the electrocardiogram electrodes 30, records vital sign measurement information (measured waveforms and measured values) on the hard disk 17, and controls display of the display 11. , lighting/flashing control of the indicator 12, sound output control by the speaker 15, and the like. Further, the processor 18 controls blinking and lighting of an indicator 25 (first indicator) of the ventilation bag 20 to be described later by transmitting an instruction signal to the ventilation bag 20 .

The processing of the processor 18 is realized by developing a program read from the hard disk 17 in the memory 16 and executing it. Details of specific display control of the display 11, lighting/blinking control of the indicator 12, and output control from the speaker 15 by the processor 18 will be described later with reference to FIG.

Here, the program can be stored and delivered to the computer using various types of non-transitory computer readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (eg, flexible discs, magnetic tapes, hard disk drives), magneto-optical recording media (eg, magneto-optical discs), CD-ROMs (Read Only Memory), CD-Rs, CD-R/W, semiconductor memory (eg, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)). The program may also be delivered to the computer on various types of transitory computer readable medium. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. Transitory computer-readable media can deliver the program to the computer via wired channels, such as wires and optical fibers, or wireless channels.

A part of the processing of the processor 18 and peripheral processing may be realized by an electronic circuit (not shown). Processing such as display of vital signs in the processor 18 is the same as in a general biological information monitor.

A timer 19 measures time under the control of the processor 18 . For example, the timer 19 measures time in response to pressing of the start button.

Next, the configuration of the ventilation bag 20 will be described with reference to FIGS. 1 and 4. FIG. A method of calculating various parameters by the processor 18 will also be described. The ventilation bag 20 has a flexible mask portion 21 , a channel 22 and a bag 23 . The ventilation bag 20 is a type of ventilation medical device that performs positive pressure ventilation for a newborn, and examples thereof include an Ambu bag and a Jackson-Ries bag. Ventilation medical devices are those that manually or automatically (semi-automatically) perform positive pressure ventilation of patients including newborns. The concept also includes a T-piece connected to a pressure source and an artificial respirator as examples of medical equipment for ventilation. In the following description, it is assumed that the ventilation bag 20 is a so-called AMBU bag.

The flexible mask part 21 is a part that contacts the nasal cavity from the oral cavity of a person to be rescued, such as a newborn baby. The bag 23 is an air bag to be pushed by the user (medical worker). The bag 23 is dented by being pushed by the user, and air is sent into the flexible mask portion 21 through the flow path 22 .

The channel 22 is a channel for feeding air from the bag 23 to the flexible mask portion 21 when the bag 23 is pushed. The flow path 22 may be provided with an air supply backflow valve and a bacteria filter.

The flow path 22 is equipped with a sensor 24 (second sensor) and an indicator 25 (first indicator). The sensor 24 acquires information on the fluid (gas) flowing through the channel 22, and corresponds to, for example, a flow sensor or a pressure sensor.

The indicator 25 and the sensor 24 are configured to be able to transmit and receive data (signals) to and from the monitoring device 10 . In this example, ventilation bag 20 transmits and receives data to and from monitoring device 10 via cable 26 . The monitoring device 10 and the ventilation bag 20 may be configured to transmit and receive data by wireless communication. In this case, it is sufficient that the ventilation bag 20 has a battery, a control device (processor, memory, storage device), etc., and has a wireless transmission function. When the monitoring device 10 and the ventilation bag 20 are wired, power may be supplied from the monitoring device 10 to the ventilation bag 20 .

Although the sensor 24 is assumed to be both a flow sensor and a pressure sensor in this example, it may be either one or another type of sensor. The flow sensor acquires the amount of air flowing toward the subject and the amount of air flowing out from the subject. The pressure sensor acquires information on the magnitude of the pressure of inspiration or expiration. The information is input to processor 18 of monitoring device 10 via cable 26 .

The above-described processor 18 uses the information on the amount of air and the information on the magnitude of pressure to obtain measurement information of parameters related to bag ventilation (also referred to as second parameters) or parameters related to respiration of the newborn (also referred to as third parameters). to calculate the measurement information of Parameters related to bag ventilation are, for example, leak rate and ventilation rate. The respiratory parameters are, for example, PIP (Peak Inspiratory Pressure) and PEEP (Positive End-Expiratory Pressure).

The processor 18 calculates, for example, the difference between the amount of air flowing toward the subject and the amount of air flowing out from the side to be inspected, and calculates the leak rate, which is the ratio of the air leaking from the flexible mask portion 21, based on the difference. calculate. Similarly, the processor 18 calculates the ventilation rate and volume from the flow sensor information using techniques commonly used in the field of bag-mask ventilation.

The processor 18 also uses the pressure information to calculate PIP and PEEP. The processor 18 may calculate the PIP value and the PEEP value based on whether it is exhalation or not and the magnitude of the pressure using a known technique.

The sensor 24 may also acquire information for calculating the so-called exhaled carbon dioxide partial pressure. Processor 18 uses this information to calculate a so-called capnogram in a known manner.

The processor 18 may detect airway blockage (a type of condition of a newborn) using the airflow information obtained by the flow sensor and the pressure information obtained by the pressure sensor. For example, the processor 18 may detect airway obstruction from arbitrary comparison processing or the like using both the exhaled volume and the detected pressure.

Note that the sensor 24 does not necessarily have to be provided in the flow path 22 and may be provided in the flexible mask portion 21 .

The indicator 25 is, for example, an LED lamp, and is configured to be lit, blink, and extinguished according to an instruction signal from the monitoring device 10 . The indicator 25 notifies information (second information) about the skill of bag ventilation by the ventilation bag 20 by flashing or lighting.

Next, a specific operation example of the neonatal treatment system 1 will be described with reference to FIG. In the description of FIG. 5, operational control of monitoring device 10 is primarily performed by processor 18 .

The neonatal treatment system 1 performs operations for supporting appropriate respiratory management and the like when a newborn is born. It is widely known that manual ventilation is desirable when a newborn baby is born if it does not cry or breathe within about 20 seconds of birth.

At the timing when the newborn baby is born, the user (medical worker) executes the start event (FIG. 5(A)). The start event in this example is assumed to be that the user presses a start button, which is a kind of operation interface 14 . The monitoring device 10 measures a certain period of time (for example, 20 seconds) from execution of the start event.

It is also possible for the user to manually time a certain period of time using a stopwatch or the like. However, since it is preferable to be able to manage the condition of the newborn along with the elapsed time since the birth of the newborn, the form of executing the start event described above is preferable.

The user presses a stop button (a kind of operation interface 14) when the newborn cries or starts breathing (FIG. 5(B)). Pressing the stop button is a kind of input that informs that the newborn is normal. The monitoring device 10 terminates time measurement when the stop button is pressed before a certain period of time elapses.

On the other hand, if the stop button is not pressed even after a certain period of time has passed since the newborn was born, the monitoring device 10 issues a notification prompting measurement of the vital sign parameter (first parameter) derived from the heartbeat of the newborn ( FIG. 5(C)). In the following example, the heartbeat-derived vital signs parameter is assumed to be the pulse rate.

For example, the processor 18 may display on the display 11 prompting the user to attach the electrocardiogram electrodes 30, or illuminate the indicator 12 in blue (the color indicating the attachment of the electrocardiogram electrodes 30) (hatched in FIG. 5C). . The processor 18 may also transmit an instruction signal instructing the indicator 25 to light up in a predetermined color. Furthermore, the processor 18 may output an alarm sound (first alarm sound) prompting the attachment of the electrocardiogram electrodes 30 from the speaker 15 (FIG. 5(C)).

Note that the indicators 12 and 25 are not necessarily lit, but may be blinking, and the lighting/blinking colors are arbitrary.

The user adheres the electrocardiogram electrodes 30 to the newborn according to the notification prompting the pulse rate measurement. The processor 18 measures the pulse rate based on the biological signals acquired from the electrocardiogram electrodes 30 and displays the measured pulse rate on the display 11 . It is desirable to measure the pulse rate over approximately 8 to 13 seconds.

The processor 18 compares the measured pulse rate with a predetermined threshold (60 in the following description), and if the pulse rate is 60 or more (if the pulse rate is normal), the pulse rate is The notification prompting the measurement (for example, the lighting of the indicator 12 or the indicator 25) ends.

On the other hand, if the pulse rate is less than 60, the monitoring device 10 notifies information (first information) prompting bag ventilation using the ventilation bag 20 (Fig. 5(D)). For example, the processor 18 may change the indicator 12 from lighting blue to lighting yellow. The processor 18 may also change the lighting color of the indicator 25 by sending an instruction signal to the ventilation bag 20 to change the lighting of the indicator 25 from blue to yellow. The processor 18 may also display a message on the display 11 such as "please ventilate the bag."

Similarly, the processor 18 may output from the speaker 15 an alarm sound (second alarm sound) for urging bag ventilation (FIG. 5(D)). By differentiating the alarm sound (first alarm sound) for prompting the attachment of the electrocardiogram electrodes 30 and the alarm sound (second alarm sound) for prompting the ventilation of the bag, the situation in which the neonatal needs treatment can be detected. It can clearly communicate that the

Of course, the processor 18 may combine the display on the display 11, the lighting or blinking of the indicators 12/25, and the output from the speaker 15 to notify the information prompting the ventilation of the bag.

The processor 18 acquires the sensing information acquired by the sensor 24 provided in the ventilation bag 20 after the notification prompting the ventilation of the bag. The sensing information is, for example, information (signal) acquired by the pressure sensor or information (signal) acquired by the flow sensor. The processor 18 calculates measurement information (measurement values and measurement waveforms) of parameters related to bag ventilation from these pieces of information. Parameters related to bag ventilation include, for example, ventilation rhythm (number of manual ventilations/minute) and leak rate (ratio of leak amount to air supply amount).

The processor 18 also calculates measurement information (measurement values and measurement waveforms) of parameters related to respiration of the subject from the sensing information of the sensor 24 . Parameters related to respiration include, for example, the above-mentioned PIP, PEEP, presence or absence of airway obstruction, exhaled carbon dioxide partial pressure, and the like.

The processor 18 detects information (second information) on how well the ventilation bag 20 performs bag ventilation based on the measurement information of parameters (second parameters) related to bag ventilation. For example, processor 18 computes information about bag ventilation proficiency from measurements of mask leak, ventilation rhythm measurements, and the like. The simplest information that indicates the proficiency of bag ventilation is a binary value of "normal bag ventilation technique" and "improvement in bag ventilation technique". For example, if at least one of the ventilation rhythm and the amount of leakage is abnormal, the processor 18 calculates that "improvement of the technique of bag ventilation is necessary" as information indicating skill of bag ventilation. Abnormalities in ventilation rhythm and leak volume may be detected by, for example, comparing measured values with threshold values.

The processor 18 notifies information (second information) indicating the skill of bag ventilation. Specifically, the processor 18 notifies the information (second information) by displaying it on the display 11, lighting or blinking of the indicator 12 or the indicator 25, sound output by the speaker 15, or a combination thereof. For example, the processor 18 may notify by lighting the indicator 25 in a color indicating normality (for example, white) or by lighting it in a color indicating abnormality (for example, yellow). Also, the characters "Leak" are displayed on the display 11 as shown in FIG. 5(E). A detailed example of display on the display 11 will be described with reference to FIG.

Next, the operation of the neonatal treatment system 1 will be described again with reference to the flowchart of FIG. When a newborn baby is born, the monitoring device 10 starts timing in response to pressing of the start button (S1).

If the stop button is pressed before a certain period of time (for example, 20 seconds) has elapsed (S2: No), the monitoring device 10 determines that the newborn is in a normal respiratory condition and terminates the process (S3).

On the other hand, if the stop button is not pressed after a certain period of time has passed (S2: Yes), the monitoring device 10 issues a notification prompting the attachment of the electrocardiogram electrodes 30 (a notification prompting measurement of the pulse rate), A pulse rate is measured (S4). If the pulse rate is not abnormal (S4: No), the monitoring device 10 determines that the newborn is in a normal state, and terminates the process (S5).

If the pulse rate is abnormal (S4: Yes), the monitoring device 10 notifies information (first information) for prompting bag ventilation with the ventilation bag 20 (S6). The notification may be, for example, by displaying a message such as "please ventilate the bag" on the display 11, or by lighting (or blinking) the indicators 12 and 25 in a predetermined color.

The monitoring device 10 detects an abnormality in the bag ventilation procedure based on the signal acquired by the sensor 24 attached to the ventilation bag 20 (S6). If no abnormality in the bag ventilation technique is detected (S6: No), the monitoring device 10 displays on the display 11 the measured value of the pulse rate (an example of the first parameter), the measured value of the PIP (an example of the third parameter), the ventilation The measured value of the rate (an example of the second parameter) and the like are displayed (S7). Note that the measured values displayed on the display 11 are not limited to those described above. The monitoring device 10 may also light or flash the indicator 12 in a color indicating that bag ventilation is normal.

On the other hand, if an abnormality in the bag ventilation technique is detected (S6: Yes), the monitoring device 10 displays the measured values of pulse rate/PIP/ventilation rate on the display 11 (S7). In addition to this, the monitoring device 10 notifies information on skillfulness of bag ventilation (second information, in this case, information notifying that improvement of technique for bag ventilation is required). Information indicating how well the bag is ventilated may be notified by lighting/blinking/color change of the indicator 12 or the indicator 25, or may be displayed on the display 11 to that effect.

Next, an example of display on the display 11 will be described with reference to FIG. FIG. 7A is a diagram showing a display example of the display 11 20 seconds after the birth of a newborn baby (after a certain period of time has passed). As shown in the figure, an elapsed time d1 (00:20) from the start event is displayed, and an indication d2 prompting attachment of the electrocardiogram electrodes 30 is displayed.

FIG. 7B is a diagram showing a display example after pulse rate measurement. As shown in the figure, an elapsed time d1 (00:32) from the start event, a pulse rate d3 (HR=52 bpm), and a display d4 (PPV) prompting ventilation with the ventilation bag 20 are displayed.

FIG. 7C is a diagram showing a first display example during bag ventilation. Elapsed time from the start event d1 (00:51), pulse rate d3 (HR = 59 bpm), ventilation rhythm d5 (Rtythm = 53/min), PIP measurement d6 (PIP = 20 cmH2O) is displayed. In addition to this, d7 is displayed, which indicates that there is a lot of leakage during bag ventilation.

FIG. 7D is a diagram showing a second display example during bag ventilation. Elapsed time from the start event d1 (01:08), pulse rate d3 (HR = 58 bpm), ventilation rhythm d5 (Rtythm = 48/min), PIP measurement d6 (PIP = 22 cmH2O) is displayed. In addition, d8 indicating airway obstruction is displayed.

Next, effects of the neonatal treatment system 1 according to this embodiment will be described. When the pulse rate (an example of the first parameter) is abnormal, the monitoring device 10 notifies the user to perform bag ventilation. As a result, bag ventilation can be started at an appropriate timing, and the respiratory condition of the newborn can be improved quickly.

In addition, the monitoring device 10 notifies information (second information) about the skill of bag ventilation after the start of bag ventilation. This allows proper bag ventilation.

The monitoring device 10 notifies information about the skill of bag ventilation by lighting or blinking of the indicator 25 (first indicator). An indicator 25 provided on the ventilation bag 20 notifies the skill of bag ventilation, so that the skill of the bag ventilation can be grasped only by looking at the technique of bag ventilation.

In addition, the monitoring device 10 may report information on the skill of bag ventilation by lighting or blinking the indicator 12 . As a result, just by looking at the monitoring device 10, the skill of bag ventilation can be grasped while referring to the display 11 displaying information on other vital signs.

Also, if there is no input notifying that the newborn is normal after a certain period of time has passed since the start event, the monitoring device 10 issues a notification prompting measurement of the pulse rate (first parameter). As a result, rapid pulse rate measurement can be started, and rapid neonatal treatment can be performed.

(Modification 1)
Next, modified examples of lighting and blinking of the indicator 25 will be described. In the above example, after the bag is ventilated, only the bag ventilation skill (second information) is notified by lighting or blinking of the indicator 12 and the indicator 25, but this is not necessarily the case. For example, the processor 18 determines whether or not the indicator 25 lights up or blinks depending on the combination of whether the measurement information of the second parameter is abnormal and whether the measurement information of the respiratory parameter (third parameter) is abnormal. An instruction signal for changing at least one of lighting color/blinking color/blinking speed may be sent to the ventilation bag 20 . This example will be described with reference to FIG.

In the example of FIG. 8, when the pulse rate (first parameter) is normal, the processor 18 does not blink or light the indicator 25 (Case 1).

If the pulse rate (first parameter) is abnormal and the other parameters (second/third parameters) are normal, processor 18 turns indicator 25 blue (indicating continued need for bag ventilation). light up (Case 2).

If the pulse rate (first parameter) and respiratory parameter (third parameter) are abnormal, processor 18 turns indicator 25 orange (indicating continued need for bag ventilation and indicating poor respiratory status). ) is turned on (Case 3).

If the pulse rate (first parameter) and the parameter related to bag ventilation (second parameter) are abnormal, the processor 18 turns the indicator 25 yellow (indicating that bag ventilation is still required and that the bag ventilation technique needs to be improved). (Case 4).

If all parameters are abnormal, processor 18 illuminates indicator 25 red (a color signaling that the neonatal condition is critical and that bag ventilation maneuvers need improvement) (Case 5).

By combining the measurement information of each parameter and changing the lighting pattern of the indicator 25 in this way, the user can grasp both the physical condition of the newborn and the skillfulness of bag ventilation just by looking at the hand where the bag is being ventilated. can be done.

(Modification 2)
The processor 18 may also inform the indicator 25 of information regarding the skillfulness of bag ventilation and the ideal ventilation speed from the indicator 25 . For example, the processor designates information (second information) indicating the skillfulness of bag ventilation by means of the color of light emitted from the indicator 25, and transmits to the ventilation bag 20 an instruction signal designating the ideal timing of bag ventilation by blinking timing. . In response to this, the indicator 25 blinks with the designated light emission color and light emission timing. The ideal bag ventilation timing may be set by default, or may be set via the operation interface 14 .

Specifically, when the bag ventilation technique does not require improvement, the processor 18 causes the indicator 25 to emit light in white (a color indicating that the bag ventilation technique is normal), and at the ideal ventilation speed. 25 is blinking. On the other hand, if the bag ventilation technique needs to be improved, the processor 18 causes the indicator 25 to emit yellow light (a color indicating that the bag ventilation technique is abnormal), and blinks the indicator 25 at the ideal ventilation speed. Let

This allows the user to grasp the ideal ventilation speed as well as the technique of bag ventilation.

(Modification 3)
Also, a modification regarding lighting/blinking control of the indicator 12 and the indicator 25 will be described. In this modified example, the information notified by the indicator 12 and the indicator 25 are different.

In this modified example, the indicator 25 is used only to report information (second information) indicating the skill of bag ventilation. Processor 18 calculates information indicative of bag ventilation proficiency in the manner described above. Processor 18 causes indicator 25 not to illuminate or flash (or to illuminate white, which is the normal color) if the bag ventilation technique does not require improvement. On the other hand, processor 18 causes indicator 25 to illuminate yellow, for example, if the bag ventilation procedure needs improvement.

On the other hand, the indicator 12 is used to inform vital sign measurement information (measurement value, measurement waveform). Vital signs include a pulse rate (measurement information of the first parameter) and respiratory parameters (third parameter) such as PIP. The processor 18 lights or blinks in an attention-grabbing color such as red when the vital sign measurement information is abnormal.

With the above configuration, it is possible to distinguish and accurately report information on the skillfulness of bag ventilation and the condition of the newborn. The above notification pattern (lighting color) is merely an example, and the processor 18 changes at least one of the presence or absence of lighting or blinking of the indicator 25/lighting color/blinking color/blinking speed to determine the skillfulness of bag ventilation. The information and the condition of the newborn can be notified separately.

The invention made by the present inventor has been specifically described above based on the embodiments, but the present invention is not limited to the embodiments already described, and various modifications can be made without departing from the scope of the invention. It goes without saying that this is possible.

For example, in the above description, the pulse rate is detected based on the biosignal acquired from the electrocardiogram electrode 30, but it is not necessarily limited to this, and any sensor (first sensor) that acquires measurement information of parameters derived from the heartbeat and the monitoring device 10 should be connected. For example, an SpO2 probe may be connected to the monitoring device 10 and the pulse rate may be calculated based on the pulse waveform. In addition to the pulse rate, the monitoring device 10 may issue a notification to encourage ventilation with the ventilation bag 20 based on measurement information (measured values and measured waveforms) of other parameters derived from the heartbeat (for example, heart sounds). good.

As described above, the ventilation bag 20 is an example of a ventilation medical device, and may be a T-piece connected to an air supply pressure source. When a T-piece is used instead of the ventilation bag 20, the T-piece has a configuration similar to the sensor 24 and the indicator 25, and has a knob for adjusting the air (gas) to be sent to the newborn. Even in this case, the T-piece and monitoring device 10 may operate in the same manner as described above.

For example, the monitoring device 10 issues a notification prompting the user to measure the pulse rate after a certain period of time has elapsed from the start event, and issues a notification prompting ventilation using the T-piece when an abnormality in the pulse rate is detected. In addition, the skill of ventilation by the T-piece (for example, the ventilation volume is abnormal because the ventilation volume setting set on the dial is not appropriate) can also be notified from the indicator 25 provided on the T-piece. Even in this case (in the case of ventilation by the T-piece instead of bag ventilation), the user can grasp the adequacy of the ventilation performed by using the T-piece by performing such notification.

In the above description, the neonatal treatment system 1 is mainly described as dealing with newborn infants, but it may be applied to condition management of infants, for example. Thus, the neonatal care system 1 is one aspect of a patient care system. Even in the case of infants, the monitoring device 10 and the ventilation bag 20 may operate in substantially the same manner as described above.
