Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a first cardiopulmonary resuscitation method 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 detailed description about steps S100, S200, and S300 is as follows.
S100: a chest impedance waveform of the patient during rescue is acquired.
The impedance refers to the resistance of a circuit having a resistor, an inductor, and a capacitor to a current in the circuit.
The chest impedance waveform of the patient during rescue can be acquired once or multiple times. The process of acquiring the chest impedance waveform of the patient during rescue can be synchronously carried out with the process of comparing the chest impedance waveform with the preset waveform, namely, the acquired partial chest impedance waveform is compared with the preset waveform while the chest impedance waveform of the patient during rescue is acquired, so that a rescuer is guided in real time, the rescuer can respond quickly according to the guidance, the timeliness of rescuing the patient is improved, and the quality of external chest compression is ensured.
S200: comparing the chest impedance waveform with a preset waveform.
The preset waveform diagram can be a chest impedance waveform diagram when the patient is rescued under ideal conditions.
In an embodiment, the preset waveform map may be an ideal waveform map obtained through multiple tests, where the preset waveform map is obtained when the rescuer is sufficiently stressed and the attention is focused.
In another embodiment, the preset waveform pattern may also be a waveform pattern downloaded from a database of the authority, so as to ensure that the obtained preset waveform pattern meets the standard specification.
In yet another embodiment, the preset waveform map may be a preset waveform map obtained after training by a neural network model. The chest impedance waveform diagram of the patient is obtained in a large amount, the obtained chest impedance waveform diagram is input into a neural network model, the input chest impedance waveform diagram is subjected to algorithm processing through data in a database, the result is output, the output result can be considered to be an ideal preset waveform diagram, and the correlation standard is met.
Further, the preset waveform diagram may be obtained by downloading in real time or may be obtained by storing in advance. When the preset waveform diagram is obtained in a real-time downloading mode, the obtained preset waveform diagram can be the latest issued waveform diagram, that is, the obtained preset waveform diagram is the waveform diagram conforming to the latest standard, so that the latest standard can be ensured to be met when the patient is subjected to cardiopulmonary resuscitation guidance. When the preset waveform diagram is obtained by pre-storing, the time consumed in the downloading process can be avoided, and the process of comparing the preset waveform diagram with the obtained waveform diagram can be completed quickly, so that timeliness of guiding a rescuer is ensured, and the quality of chest compression is further ensured.
The "S200: comparing the chest impedance waveform with a preset waveform includes, but is not limited to, the following steps.
Comparing the waveform parameters of the chest impedance waveform diagram with the waveform parameters of a preset waveform diagram, 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 comparison is performed between a waveform diagram obtained when the patient is rescued and a preset waveform diagram, and the comparison index can be the frequency, amplitude, complete period and the like of the two waveform diagrams. Then feeding back to the rescuer according to the comparison result, and rescuing the patient according to the comparison result. Specific guidance is provided in the following description, not otherwise provided herein.
According to the cardiopulmonary resuscitation guiding method, firstly, the chest impedance waveform diagram of a patient during rescuing is obtained, then the obtained chest impedance waveform diagram is compared with the preset waveform diagram, wherein the preset waveform diagram is the chest impedance waveform diagram of the patient during rescuing under ideal conditions, and finally, a rescuer is guided to rescue the patient according to the 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.
With continued reference to fig. 2, fig. 2 is a flowchart of a second cardiopulmonary resuscitation method according to an embodiment of the present invention. The second cardiopulmonary resuscitation method is substantially the same as the first cardiopulmonary resuscitation method, except for the steps of "S200: comparing the frequency corresponding to the chest impedance waveform with the frequency corresponding to the preset waveform, and step S300: and sending prompt information according to the comparison result, wherein the prompt information is used for guiding a rescuer to rescue the patient, and comprises, but is not limited to, steps S210 and S220, and the detailed description of the steps S210 and S220 is as follows.
S210: and comparing the frequency corresponding to the chest impedance waveform diagram with the frequency corresponding to the preset waveform diagram.
Where the frequency is the number of times the periodic change is completed per unit time, and is an amount describing how frequently the periodic movement is. In general, when an unskilled rescuer performs chest compressions on a patient, possibly due to fear psychology, the frequency of the compressions is usually smaller than the frequency corresponding to a preset waveform, and the standard compression frequency corresponding to the preset waveform is usually 100ppm.
S220: when the frequency corresponding to the chest impedance waveform diagram is smaller than the frequency corresponding to the preset waveform diagram, prompt information is sent to the rescuer, and the prompt information prompts the rescuer to improve the pressing speed when the patient is pressed outside the chest.
And comparing the chest impedance waveform diagram obtained when the patient is rescued with a preset waveform diagram in real time, and prompting a rescuer to accelerate the pressing speed when the patient is pressed outside the chest when the frequency corresponding to the obtained chest impedance waveform diagram is detected to be smaller than the frequency corresponding to the preset waveform diagram, so as to ensure the quality of the patient pressed outside the chest.
It can be appreciated that in other embodiments, the chest impedance waveform obtained when the patient is rescued is compared with the preset waveform in real time, and when the frequency corresponding to the obtained chest impedance waveform is detected to be greater than the frequency corresponding to the preset waveform, the rescuer is prompted to slow down the pressing speed when the patient is chest pressed, so as to ensure the quality of chest pressing of the patient. When the frequency corresponding to the acquired chest impedance waveform is detected to be consistent with the frequency corresponding to the preset waveform, no prompt message is sent out, or the normal pressing is prompted, and the current pressing frequency is kept.
With continued reference to fig. 3, fig. 3 is a flowchart of a third cardiopulmonary resuscitation method according to an embodiment of the present invention. The third cardiopulmonary resuscitation method is substantially the same as the first cardiopulmonary resuscitation method, except for step "S200: comparing the frequency corresponding to the chest impedance waveform with the frequency corresponding to the preset waveform, and step S300: and sending prompt information according to the comparison result, wherein the prompt information is used for guiding a rescuer to rescue the patient, and comprises, but is not limited to, steps S230 and S240, and the detailed description of the steps S230 and S240 is as follows.
S230: and comparing the amplitude corresponding to the chest impedance waveform diagram with the amplitude corresponding to the preset waveform diagram.
Wherein the amplitude is half the peak-to-trough distance over a period. In general, for unskilled rescuers, chest compressions may be performed on the patient, possibly due to fear psychology, with the amplitude of the compressions generally being less than the frequency corresponding to the preset waveform pattern.
The amplitude of the acquired chest impedance waveform is compared with the amplitude of the preset waveform, and only the amplitude of the preset waveform is required to be subjected to difference operation, so that the difference between the amplitude of the acquired chest impedance waveform and the amplitude of the preset waveform can be intuitively acquired, and the chest compression process of a rescuer can be guided in real time according to the difference, so that the compression quality of chest compression is improved.
S240: when the amplitude corresponding to the chest impedance waveform diagram is smaller than the amplitude corresponding to the preset waveform diagram, prompt information is sent to the rescuer, and the prompt information prompts the rescuer to increase the pressing depth when the chest compression is performed on the patient.
And comparing the chest impedance waveform diagram obtained when the patient is rescued with a preset waveform diagram in real time, and prompting a rescuer to increase the compression depth when the patient is subjected to chest compression when the amplitude corresponding to the obtained chest impedance waveform diagram is detected to be smaller than the amplitude corresponding to the preset waveform diagram so as to ensure the quality of chest compression on the patient.
Wherein, the compression depth is related to the compression force to a certain extent, and therefore, the compression depth when chest compression is performed on the patient can be increased by increasing the compression force.
It can be appreciated that in other embodiments, the chest impedance waveform obtained when the patient is rescued is compared with the preset waveform in real time, and when the amplitude corresponding to the obtained chest impedance waveform is detected to be smaller than the amplitude corresponding to the preset waveform, the rescuer is prompted to reduce the compression depth when the patient is chest compressed, so as to ensure the quality of chest compression on the patient. When the amplitude corresponding to the acquired chest impedance waveform diagram is detected to be consistent with the amplitude corresponding to the preset waveform diagram, no prompt message is sent out, or the normal pressing is prompted, and the current pressing depth is kept continuously.
With continued reference to fig. 4, fig. 4 is a flowchart of a fourth cardiopulmonary resuscitation method according to an embodiment of the present invention. The fourth cardiopulmonary resuscitation guidance method is substantially the same as the first cardiopulmonary resuscitation guidance method, except for step "S200: comparing the frequency corresponding to the chest impedance waveform with the frequency corresponding to the preset waveform, and step S300: and sending prompt information according to the comparison result, wherein the prompt information is used for guiding a rescuer to rescue the patient and comprises, but is not limited to, steps S250 and S260, and the detailed description of the steps S250 and S260 is as follows.
S250: comparing the chest impedance waveform diagram with a preset waveform diagram to judge whether the cycle of the chest impedance waveform diagram is complete.
Where a cycle is the time required to complete a complete waveform change. Since there is a correspondence between the period of chest compressions and the frequency of heart beats, whether the chest compression period is complete will directly affect the heart's beat frequency. The standard preset waveform chart generally shows obvious periodic variation, but for unskilled rescuers, the acquired chest impedance waveform chart for rescuing patients usually has no obvious period, so whether the chest compressions of the patients for rescuing accord with the standard can be judged according to whether the period of the acquired chest impedance waveform chart is complete, and the rescuers are informed of adopting corresponding guiding strategies for rescuing the patients.
S260: when the cycle of the chest impedance waveform diagram is incomplete, prompt information is sent to the rescuer, and the prompt information prompts the rescuer to increase the speed of the hands of the rescuer leaving the body of the patient when the rescuer presses the chest of the patient.
The chest impedance waveform diagram obtained when the patient is rescued is compared with the preset waveform diagram in real time, when the period corresponding to the obtained chest impedance waveform diagram is detected to be incomplete, the fact that the rebound of the chest compression is insufficient when the patient is subjected to the chest compression is indicated, and when the patient is subjected to the chest compression by a rescuer is prompted, the speed of the hands of the rescuer leaving the body of the patient is improved. In addition, the compression force also affects the period corresponding to the acquired chest impedance waveform, so in some embodiments, the compression force during chest compression needs to be adjusted synchronously, and the integrity of the period during chest compression on the patient can be ensured by increasing the compression force.
It can be appreciated that in other embodiments, the chest impedance waveform obtained when rescuing the patient is compared with the preset waveform in real time, and when the period corresponding to the obtained chest impedance waveform is detected to be incomplete, the rescuer is prompted to reduce the speed of leaving the hands of the patient, so as to ensure the quality of chest compressions performed on the patient. When the waveform integrity corresponding to the acquired chest impedance waveform diagram is detected to be consistent with the waveform integrity corresponding to the preset waveform diagram, no prompt message is sent out, or the normal pressing is prompted, and the current pressing state is kept continuously.
With continued reference to fig. 5, fig. 5 is a flowchart of a fifth cardiopulmonary resuscitation method according to an embodiment of the present invention. The fifth cardiopulmonary resuscitation method is substantially the same as the first cardiopulmonary resuscitation method, except for the steps of "S100: prior to acquiring the chest impedance waveform "of the patient at the time of rescue, the cardiopulmonary resuscitation guidance method further includes, but is not limited to, steps S80 and S90, and the detailed description of steps S80 and S90 is as follows.
S80: the electrode plate is adhered to a preset part of the body of the patient, and an initial impedance value of the patient when not being rescued is obtained.
Whether the electrode plate is normally attached to the preset part of the patient body directly influences the pressing quality during chest compression, so that the attachment of the electrode plate is equivalent to the preprocessing process of chest compression.
The initial impedance corresponds to the impedance value of the patient's body in the quiescent state. And judging whether the electrode slice is attached or not by measuring an initial impedance value when chest compression is not carried out on the patient. If the electrode plate is normally attached to the preset part of the patient body, the subsequent chest compression process can be started on the patient, and if the electrode plate is not normally attached to the preset part of the patient body, the position of the electrode plate on the patient body needs to be adjusted so that the electrode plate is in a normally attached state.
S90: judging whether the electrode plate is in a normal attaching state according to the initial impedance value.
Specifically, the resistance corresponding to the electrode sheet in the normal bonding state should be in the range of 100 ohms to 600 ohms. When the resistance value measured according to the electrode sheet is greater than 600 ohms, it may be because the electrode sheet is not completely attached to the patient's body, so that the circuit for detecting the resistance on the electrode sheet exhibits an open circuit effect. When the resistance measured from the electrode sheets is less than 100 ohms, it may be because the distance between the two electrode sheets is too close, and thus, it is necessary to adaptively adjust the distance between the two electrode sheets so that the resistance measured from the electrode sheets is within a preset range. The impedance and the resistance have a corresponding relation, and when the resistance 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 sheet is attached to the human body, the equivalent impedance is as shown in fig. 6. Wherein Z1 and Z2 are equivalent impedance models of the electrode plate contacted with a 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 the chest impedance Z3 of the human body, and a corresponding impedance value can be obtained after the signal amplitudes at two ends of the Z3 are sampled and calculated 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.
With continued reference to fig. 7, fig. 7 is a flowchart of a sixth cardiopulmonary resuscitation method according to an embodiment of the present invention. The sixth cardiopulmonary resuscitation method is substantially the same as the fifth cardiopulmonary resuscitation method, except for the step of "S90: judging whether the electrode sheet is in the normal bonding state "according to the initial impedance value includes, but is not limited to, steps S91, S92 and S93, and is described below 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: when the initial impedance value is between the first threshold value and the second threshold value, the electrode plate is judged to be in a normal attaching state.
When the electrode slice is in a normal fitting state, the chest compression operation can be carried out on a 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, judging that the electrode plate is in an abnormal fitting state, and sending prompt information to a rescuer to guide the rescuer to re-fit the electrode plate.
When the electrode plate is in an abnormal attaching state, a rescuer needs to be reminded of attaching the electrode plate again, and when the electrode plate is in a normal attaching state, the chest compression operation is performed on the patient.
With continued reference to fig. 8, fig. 8 is a flowchart of a seventh cardiopulmonary resuscitation method according to an embodiment of the present invention. The seventh cardiopulmonary resuscitation method is substantially the same as the first cardiopulmonary resuscitation method, except for the steps of "S92: after determining that the electrode pad is in the normal fit state "when the initial impedance value is between the first threshold value and the second threshold value, the cardiopulmonary resuscitation guidance method further includes, but is not limited to, steps S921, S922, S923, and S924, and the following description is given with respect to steps S921, S922, S923, and S924.
S921: an electrocardiogram signal of the patient is acquired.
Among them, an Electrocardiogram (ECG) is a technique of recording an electrical activity change pattern generated by the heart every cardiac cycle from a body surface using an electrocardiograph.
S922: whether the patient is in a shockable rhythm state is judged according to the electrocardiogram signal.
Where shockable rhythm refers to a state that satisfies electrical defibrillation. Electrical defibrillation is a method of striking the heart with a certain amount of current to terminate ventricular fibrillation, and is an effective method of treating ventricular fibrillation. In addition to internal defibrillation (ventricular fibrillation) by using alternating current in the current heart operation process, direct current defibrillation is generally used.
S923: when the patient is in a shockable rhythm state, the charging circuit is turned on.
S924: after the charging circuit finishes charging, the rescuer is prompted to start the discharging circuit so as to discharge the patient for treatment.
Wherein the discharge therapy is electric defibrillation therapy. In an embodiment, the charging circuit is pre-charged in advance, so that the energy storage unit stores enough electric quantity, when the patient is detected to be in the shockable rhythm state, the rescuer is directly prompted to perform discharge treatment on the patient, so that the time for charging and storing can be saved, the timeliness of rescuing the patient is improved, the quality of chest compression on the patient is ensured, and the rescuing mode is a semi-automatic rescuing mode, and the rescuer is required to participate in defibrillation discharge treatment.
With continued reference to fig. 9, fig. 9 is a flowchart of an eighth cardiopulmonary resuscitation method according to an embodiment of the present invention.
