Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart illustrating a first method for guiding cpr according to an embodiment of the present invention. In the present embodiment, the cardiopulmonary resuscitation guidance method includes, but is not limited to, steps S100, S200, and S300, and the detailed description of steps S100, S200, and S300 is as follows.

S100: obtaining a thoracic impedance oscillogram of the patient during rescue.

Impedance refers to the resistance of a circuit having a resistor, an inductor, and a capacitor to a current in the circuit.

The method for acquiring the thoracic impedance oscillogram of the patient during rescue can be one-time acquisition or multiple-time acquisition. The process of obtaining the chest impedance oscillogram of the patient during rescue can be synchronously carried out with the process of comparing the chest impedance oscillogram with the preset oscillogram, namely, the chest impedance oscillogram of the patient during rescue is obtained, and part of the obtained chest impedance oscillogram is compared with the preset oscillogram, so that the rescuer is guided in real time, the rescuer can quickly respond according to the guidance, the timeliness of rescuing the patient is improved, and the quality of chest compression is ensured.

S200: and comparing the thoracic impedance oscillogram with a preset oscillogram.

The preset oscillogram can be a thoracic impedance oscillogram when a patient is rescued under an ideal condition.

In an embodiment, the preset waveform diagram may be an ideal waveform diagram obtained through multiple tests, where the preset waveform diagram refers to a waveform diagram obtained when the rescuer has sufficient physical strength and focuses attention.

In another embodiment, the preset waveform may also be a waveform downloaded from a database of the authorities, thereby ensuring that the obtained preset waveform is in compliance with the standard specification.

In yet another embodiment, the preset waveform may be a preset waveform obtained after training through a neural network model. The method comprises the steps of obtaining a large number of thoracic impedance oscillograms when a patient is rescued, inputting the obtained thoracic impedance oscillograms into a neural network model, carrying out algorithm processing on the input thoracic impedance oscillograms through data in a database, outputting results, and enabling the output results to be considered as ideal preset oscillograms and to accord with relevant standards.

Further, the preset waveform map may be obtained by downloading in real time, or may be obtained by storing in advance. When the preset oscillogram is acquired in a real-time downloading mode, the acquired preset oscillogram can be the latest released oscillogram, namely the acquired preset oscillogram is the oscillogram which meets the latest specification, so that the cardio-pulmonary resuscitation guidance of a patient can be ensured to meet the latest standard. When the preset oscillogram is obtained by pre-storing, the time consumed in the downloading process can be avoided, and the process of comparing the preset oscillogram with the obtained oscillogram can be quickly completed by adopting the preset oscillogram, so that the timeliness of guiding the rescuer is ensured, and the chest compression quality is further ensured.

The step of "S200: comparing the thoracic impedance profile to a predetermined profile includes, but is not limited to, the following steps.

And comparing the waveform parameters of the thoracic impedance oscillogram with the waveform parameters of a preset oscillogram, wherein the waveform parameters comprise at least one of frequency, amplitude and period.

S300: and sending out prompt information according to the comparison result, wherein the prompt information is used for guiding a rescuer to rescue the patient.

The oscillogram obtained when the patient is rescued is compared with a preset oscillogram, and the comparison indexes can be the conditions of comparing the frequency, the amplitude, the complete period and the like of the two oscillograms. And then feeding back to the rescuer in real time according to the comparison result, and rescuing the patient by the rescuer according to the comparison result. For specific guidance, reference is made to the following description, which is not to be construed as being overly limiting.

The cardiopulmonary resuscitation guidance method comprises the steps of firstly obtaining a thoracic impedance oscillogram of a patient during rescue, then comparing the obtained thoracic impedance oscillogram with a preset oscillogram, wherein the preset oscillogram is the thoracic impedance oscillogram of the patient during rescue under an ideal condition, and finally guiding a rescuer to rescue the patient according to a comparison result. The cardiopulmonary resuscitation guidance method provided by the embodiment of the invention is used for guiding the actual rescue process of cardiopulmonary resuscitation and is beneficial to ensuring the quality of chest compression.

Referring to fig. 2, fig. 2 is a flowchart illustrating a second method for guiding cpr according to an embodiment of the present invention. The second cpr coaching method is substantially the same as the first cpr coaching method except that the step "S200: comparing the frequency corresponding to the thoracic impedance oscillogram with the frequency corresponding to the preset oscillogram and the step S300: sending out prompt information according to the comparison result, wherein the prompt information is used for guiding the rescuer to rescue the patient, and the steps include, but are not limited to, steps S210 and S220, and the detailed description about the steps S210 and S220 is as follows.

S210: and comparing the frequency corresponding to the thoracic impedance oscillogram with the frequency corresponding to the preset oscillogram.

Where frequency is the number of times a periodic change is made per unit time and is a quantity describing how frequently the periodic movement is. Generally, for unskilled rescuers, the frequency of chest compression performed on a patient is usually less than the frequency corresponding to the preset waveform diagram, which is usually 100ppm, probably due to fear.

S220: when the frequency corresponding to the thoracic impedance oscillogram is less than the frequency corresponding to the preset oscillogram, prompt information is sent to a rescuer, and the prompt information prompts the rescuer to improve the compression speed when the rescuer performs chest compression on the patient.

The chest impedance oscillogram acquired when the patient is rescued is compared with the preset oscillogram in real time, and when the fact that the frequency corresponding to the acquired chest impedance oscillogram is smaller than the frequency corresponding to the preset oscillogram is detected, the rescuer is prompted to accelerate the pressing speed when chest pressing is carried out on the patient, so that the chest pressing quality of the patient is guaranteed.

It can be understood that, in other embodiments, the thoracic impedance oscillogram acquired when the patient is rescued is compared with the preset oscillogram in real time, and when it is detected that the frequency corresponding to the acquired thoracic impedance oscillogram is greater than the frequency corresponding to the preset oscillogram, the rescuer is prompted to slow down the pressing speed when the chest pressing is performed on the patient, so as to ensure the quality of the chest pressing performed on the patient. When the frequency corresponding to the acquired thoracic impedance oscillogram is detected to be consistent with the frequency corresponding to the preset oscillogram, no prompt message is sent out, or normal pressing is prompted, and the current pressing frequency is continued to be maintained.

Referring to fig. 3, fig. 3 is a flowchart illustrating a third method for guiding cardiopulmonary resuscitation according to an embodiment of the present invention. The third cpr coaching method is substantially the same as the first cpr coaching method except that the step "S200: comparing the frequency corresponding to the thoracic impedance oscillogram with the frequency corresponding to the preset oscillogram and the step S300: sending out prompt information according to the comparison result, wherein the prompt information is used for guiding the rescuer to rescue the patient, including but not limited to steps S230 and S240, and the detailed description about steps S230 and S240 is as follows.

S230: and comparing the amplitude corresponding to the thoracic impedance oscillogram with the amplitude corresponding to the preset oscillogram.

Wherein the amplitude is half the peak to trough distance over a period. Generally, for unskilled rescuers, the amplitude of chest compression is usually less than the frequency corresponding to the preset waveform pattern, which may be a fear of mind when performing chest compression on a patient.

The amplitude of the acquired chest impedance oscillogram is compared with the amplitude of the preset oscillogram, and only the difference value operation needs to be carried out on the amplitude of the preset oscillogram and the amplitude of the acquired chest impedance oscillogram, so that the difference value between the amplitude of the acquired chest impedance oscillogram and the amplitude of the preset oscillogram can be acquired very intuitively, and the chest compression process of a rescuer can be guided in real time according to the difference value, and the chest compression quality is improved.

S240: when the amplitude corresponding to the thoracic impedance oscillogram is smaller than the amplitude corresponding to the preset oscillogram, prompt information is sent to the rescuer, and the prompt information prompts the rescuer to increase the compression depth when the chest compression is carried out on the patient.

The chest impedance oscillogram acquired when the patient is rescued is compared with the preset oscillogram in real time, and when the fact that the amplitude corresponding to the acquired chest impedance oscillogram is smaller than the amplitude corresponding to the preset oscillogram is detected, the rescuer is prompted to increase the pressing depth when chest pressing is carried out on the patient, so that the chest pressing quality of the patient is guaranteed.

Here, the compression depth is related to the degree of compression to some extent, and therefore, the compression depth at the time of chest compression on the patient can be increased by increasing the degree of compression.

It can be understood that, in other embodiments, the chest impedance oscillogram acquired when the patient is rescued is compared with the preset oscillogram in real time, and when the amplitude corresponding to the acquired chest impedance oscillogram is detected to be smaller than the amplitude corresponding to the preset oscillogram, the rescuer is prompted to reduce the compression depth when the chest compression is performed on the patient, so as to ensure the quality of the chest compression performed on the patient. When the amplitude corresponding to the acquired thoracic impedance oscillogram is detected to be consistent with the amplitude corresponding to the preset oscillogram, no prompt information is sent out, or normal pressing is prompted, and the current pressing depth is continued to be maintained.

Referring to fig. 4, fig. 4 is a flowchart illustrating a fourth method for guiding cardiopulmonary resuscitation according to an embodiment of the present invention. The fourth cpr coaching method is substantially the same as the first cpr coaching method except that the step "S200: comparing the frequency corresponding to the thoracic impedance oscillogram with the frequency corresponding to the preset oscillogram and the step S300: sending out prompt information according to the comparison result, wherein the prompt information is used for guiding the rescuer to rescue the patient, and the steps include, but are not limited to, steps S250 and S260, and the detailed description about the steps S250 and S260 is as follows.

S250: and comparing the thoracic impedance oscillogram with a preset oscillogram to judge whether the period of the thoracic impedance oscillogram is complete.

Where the period is the time required to complete one complete waveform change. Since there is a correspondence between the period of chest compressions and the frequency of the heart beat, whether the chest compression period is complete will directly affect the beat frequency of the heart. The standard preset oscillogram generally shows obvious periodic variation, and for unskilled rescuers, the acquired thoracic impedance oscillogram for rescuing patients generally has no obvious period, so that whether chest compression meets the standard or not during rescuing patients can be judged according to whether the period of the acquired thoracic impedance oscillogram is complete, and the rescuers are informed to rescue the patients by adopting a corresponding guidance strategy.

S260: when the period of the thoracic impedance oscillogram is incomplete, prompt information is sent to the rescuer, and the prompt information prompts the rescuer to improve the speed of the rescuer that the hands leave the body of the patient when the rescuer performs chest compression on the patient.

The chest impedance oscillogram obtained when the patient is rescued is compared with the preset oscillogram in real time, when the fact that the corresponding period of the obtained chest impedance oscillogram is incomplete is detected, pressing resilience of the patient during chest pressing is insufficient, and when the rescuer is prompted to perform chest pressing on the patient, the speed of the rescuer that the hands leave the body of the patient is improved. In addition, the degree of compression also affects the period corresponding to the acquired thoracic impedance oscillogram, so in some embodiments, the degree of compression during chest compression needs to be synchronously adjusted, and the completeness of the period during chest compression on a patient can be ensured by increasing the degree of compression.

It can be understood that, in other embodiments, the thoracic impedance oscillogram acquired when the patient is rescued is compared with the preset oscillogram in real time, and when the incomplete period corresponding to the acquired thoracic impedance oscillogram is detected, the rescuer is prompted to reduce the speed of the hand leaving the body of the patient, so as to ensure the quality of the chest compression on the patient. When the waveform integrity degree corresponding to the acquired thoracic impedance oscillogram is detected to be consistent with the waveform integrity degree corresponding to the preset oscillogram, no prompt message is sent, or normal pressing is prompted, and a current pressing state is continued to be maintained.

Referring to fig. 5, fig. 5 is a flowchart illustrating a fifth method for guiding cpr according to an embodiment of the present invention. The fifth cpr coaching method is substantially the same as the first cpr coaching method except that, at step "S100: before acquiring the thoracic impedance oscillogram of the patient during rescue, "the cpr guidance method further includes, but is not limited to, steps S80 and S90, and the details of steps S80 and S90 are as follows.

S80: and adhering the electrode slice to a preset part of the body of the patient, and acquiring an initial impedance value of the patient when the patient is not rescued.

Whether the electrode plates are normally attached to preset parts of the body of a patient directly influences the compression quality during chest compression, and therefore the attachment of the electrode plates is equivalent to the pretreatment process of chest compression.

The initial impedance corresponds to the impedance value of the patient's body at rest. Whether the electrode plate is attached or not is judged by measuring an initial impedance value when chest compression is not performed on a patient. If the electrode slice is normally attached to the preset part of the body of the patient, the subsequent external chest compression process can be started for the patient, and on the contrary, if the electrode slice is not normally attached to the preset part of the body of the patient, the position of the electrode slice on the body of the patient needs to be adjusted, so that the electrode slice is in a normally attached state.

S90: and judging whether the electrode plate is in a normal attaching state or not according to the initial impedance value.

Specifically, the resistance value corresponding to the electrode sheet in the normal attaching state should be in a range of 100 ohms to 600 ohms. When the resistance measured according to the electrode sheet is greater than 600 ohms, it may be because the electrode sheet is not completely attached to the body of the patient, so that the circuit of the detection resistor on the electrode sheet has an open circuit effect. When the resistance measured according to the electrode sheets is less than 100 ohms, it may be because the distance between the two electrode sheets is too close, and thus, the distance between the two electrode sheets needs to be adaptively adjusted so that the resistance measured according to the electrode sheets is within a preset range. The resistance value and the impedance have a corresponding relation, and when the resistance value is within a preset range, the impedance also accords with a normal value.

Further, with continued reference to FIG. 6, for the measurement of the patient's body impedance values, a circuit schematic as in FIG. 6 may be employed. When the electrode pad is attached to a human body, the equivalent impedance is as shown in fig. 6. Wherein Z1 and Z2 are equivalent impedance models of the electrode sheet contacting with the human body. When an alternating current carrier signal with a certain frequency is driven to a human body, a certain signal amplitude can be obtained on a chest resistance Z3 of the human body, and a corresponding impedance value can be obtained by sampling the signal amplitudes at two ends of Z3 and calculating through a certain algorithm. When the electrode plate is well connected with a human body, a stable impedance value can be measured by an alternating current small signal method.

Referring to fig. 7, fig. 7 is a flowchart illustrating a sixth method for guiding cpr according to an embodiment of the present invention. The sixth cpr coaching method is substantially the same as the fifth cpr coaching method except that the step "S90: the "determination of whether or not the electrode sheet is in the normal attached state based on the initial resistance value" includes, but is not limited to, steps S91, S92, and S93, and the following is introduced with respect to steps S91, S92, and S93.

S91: and judging whether the initial impedance value is between a first threshold value and a second threshold value, wherein the first threshold value is smaller than the second threshold value.

The first threshold may be an impedance value corresponding to a resistance of 100 ohms, and the second threshold may be an impedance value corresponding to a resistance of 600 ohms.

S92: and when the initial impedance value is between the first threshold value and the second threshold value, judging that the electrode plate is in a normal attaching state.

When the electrode slice is in a normal attaching state, the external chest compression operation can be performed on the patient.

S93: when the initial impedance value is smaller than the first threshold value or the initial impedance value is larger than the second threshold value, the electrode plate is judged to be in an abnormal attaching state, and prompt information is sent to a rescuer to guide the rescuer to attach the electrode plate again.

When the electrode slice is in the abnormal attaching state, the rescuers need to be reminded to attach the electrode slice again, and when the electrode slice is in the normal attaching state, the external chest pressing operation is carried out on the patient again.

Referring to fig. 8, fig. 8 is a flowchart illustrating a seventh cpr guidance method according to an embodiment of the present invention. The seventh cpr coaching method is substantially the same as the first cpr coaching method except that, at step "S92: after determining that the electrode pads are in the normal fit state "when the initial impedance value is between the first threshold and the second threshold, the cpr guidance method further includes, but is not limited to, steps S921, S922, S923, and S924, which are described below with respect to steps S921, S922, S923, and S924.

S921: an electrocardiogram signal of the patient is acquired.

Among them, Electrocardiogram (ECG) is a technique of recording a pattern of change in electrical activity generated every cardiac cycle of a heart from a body surface using an electrocardiograph.

S922: whether the patient is in a shockable rhythm is determined from the electrocardiogram signal.

A shockable rhythm refers to a state that satisfies electrical defibrillation, among other things. Electrical defibrillation, which is a method of stopping ventricular fibrillation by striking the heart with a certain amount of current, is an effective method of treating ventricular fibrillation. At present, except that the in vivo defibrillation (ventricular fibrillation) is carried out by using alternating current in the heart operation process, the defibrillation is generally carried out by using direct current.

S923: when the patient is in a shockable rhythm, the charging circuit is turned on.

S924: after the charging circuit finishes charging, the rescuer is prompted to start the discharging circuit to perform discharging treatment on the patient.

The discharge therapy is electrical defibrillation therapy. In an embodiment, precharge charging circuit in advance to make energy storage unit store sufficient electric quantity, when detecting that the patient is in the rhythm state of can shocking by electricity, direct suggestion rescuer carries out the treatment of discharging to the patient, thereby can save the time of charging storage, the timeliness when helping improving the patient to salvage, and then ensure to carry out the quality of pressing outside the chest to the patient, this kind of rescue mode is the rescue mode of a semi-automatic formula, needs the rescuer to participate in the discharge treatment of defibrillating.

Referring to fig. 9, fig. 9 is a flowchart illustrating an eighth method for guiding cardiopulmonary resuscitation according to an embodiment of the present invention. The eighth cpr coaching method is substantially the same as the first cpr coaching method except that, at step "S92: after determining that the electrode pad is in the normal fit state "when the initial impedance value is between the first threshold and the second threshold, the cpr guidance method further includes, but is not limited to, steps S925, S926, and S927, which are described below with respect to steps S925, S926, and S927.

S925: an electrocardiogram signal of the patient is acquired.

S926: whether the patient is in a shockable rhythm is determined from the electrocardiogram signal.

S927: when the patient is in the shockable rhythm state, after a preset time period, the patient is automatically subjected to discharge treatment.

Specifically, automatic external defibrillation equipment has timing circuit, and when the patient satisfied the condition of shock defibrillation, timing circuit opened immediately, and timing circuit has the countdown function, and after the length of time of predetermineeing, the automatic treatment of defibrillating of shocking to the patient to the time of control rescue that can be more accurate. The rescue mode is a full-automatic rescue mode, and is automatically completed by automatic external defibrillation equipment without a rescuer participating in defibrillation discharge treatment.

Referring to fig. 10, fig. 10 is a flowchart illustrating a ninth method for guiding cardiopulmonary resuscitation according to an embodiment of the present invention. The ninth cpr coaching method is substantially the same as the first cpr coaching method except that the "S925: acquiring an electrocardiogram signal of the patient "includes, but is not limited to, steps S9251, S9252 and S9253, and detailed descriptions about steps S9251, S9252 and S9253 are as follows.

S9251: a first signal is detected when the electrode patch is attached to the patient's body.

S9252: it is determined whether a second signal characteristic of the pacemaker is present in the first signal.

Among them, pacemakers are important components of pacing systems. The pacing system consists of a pacemaker, a pacing electrode lead and a program controller. Wherein the pacemaker and the pacing electrode lead are implanted in a human body. The pacemaker consists of a circuit and a battery mounted in a metal case.

The pacemaker sends tiny electric pulses to the heart when needed, and the pacing electrode lead consists of insulated leads and is responsible for transmitting the tiny electric pulses to the heart to stimulate the heart to beat.

S9253: when the second signal which is characterized by the pacemaker exists in the first signal, the electrocardiogram signal is obtained by subtracting the second signal from the first signal, and when the second signal which is characterized by the pacemaker does not exist in the first signal, the first signal is set as the electrocardiogram signal.

When the patient wears the pacemaker, the pacemaker can interfere with the judgment of whether the patient meets the electric shock condition, so that the interference of the pacemaker can be removed in the embodiment to avoid misjudgment.
