The prescription value generator PG of the control module CM receives the sensing information BA. The prescription value generating unit PG calculates the prescription value CA based on the sensing information BA. The prescription value generator PG transmits the calculated prescription value CA to the output signal generator SG.

The prescription value CA may be calculated by comparing height information of the patient PT among sensing information with pre-stored Broselow tape information. Broselow tape information may be stored in a storage unit (not shown) of the control module CM. The Broslow tape includes medical instructions, such as the appropriate dosage of medication for the patient (PT), the size of equipment to be used, and the level of shock voltage when using a defibrillator, based on the patient's (PT) height.

The prescription value generation unit PG may generate a prescription value by classifying the patient PT into an adult and an infant based on height information of the patient PT. For example, when the height of the patient PT is included in the height range of the Broselow tape, the prescription value generating unit PG may determine that the patient PT is an infant. In addition, the prescription value generation unit PG may generate a prescription value including information that the depth of chest compression recommended during cardiopulmonary resuscitation is 4 cm. When the height of the patient PT is not included in the height range of the Broselow tape, the prescription value generating unit PG may determine that the patient PT is an adult. In addition, the prescription value generating unit PG may generate a prescription value including content that the depth of chest compression recommended during cardiopulmonary resuscitation is 5 cm or more and 6 cm or less. Therefore, the CPR guide system (CGS) utilizes the height information of the patient (PT) and the Broselow tape information measured through the lidar sensor (LDS, FIG. 2) to inform the user (USR) of the patient ( PT) can provide customized CPR information.

In an embodiment of the present invention, the first output signal DA may be transmitted to the body output module MPO. The second output signal DB may be transmitted to the detachable output module RMO. In another embodiment of the present invention, the second output signal DB may not be transmitted to the detachable output module RMO. That is, the output signal DA can be received only by the body output module MPO.

The CPR recommendation information may include at least one of a recommended compression position, compression depth, and compression speed when performing CPR.

The CPR performance information may include at least one of first sensing information and second sensing information. That is, the CPR performance information may correspond to at least one of a location of compression, a depth of compression, and a speed of compression in CPR performed by the actual user (USR).

The CPR evaluation information may include a comparison result of comparing the CPR recommendation information and CPR performance information.

In an embodiment of the present invention, the body output module (MPO) may output CPR guide information corresponding to the first output signal (DA). The detachable output module (RMO) may output CPR guide information corresponding to the second output signal (DB). In another embodiment of the present invention, the detachable output module (RMO) may not provide CPR guide information. In this case, the user USR may be provided with CPR guide information only through the body output module MPO.

It can be set to zero. That is, the measured value of the inertial sensor at the critical pressure time point TT1 may be set as the zero point of the inertial sensor. The critical pressure time point TT1 may be the first time point when the value measured by the pressure sensor becomes greater than the preset reference value SS. The reference value SS may be set as a minimum pressure value capable of applying effective compression to the chest of the patient PT. Illustratively, the reference value SS is 10

can be However, the present invention is not limited by the reference value SS. The reference value (SS) according to the present invention can be set and changed arbitrarily by the user (USR).

It may be determined that chest compression has started from the critical pressure point (TT1). By adjusting the zero point of the inertial sensor based on the critical pressure time point TT1, errors caused by previous data can be removed.

As described above, according to the present invention, the CPR guide system (CGS) measures the height of the patient (PT) using the lidar sensor (LDS), and provides customized CPR guide information for each patient based on this. can In addition, since the user (USR) can receive feedback on CPR in various forms including Augmented Reality (AR) images, accurate CPR can be performed.

일 수 있다. 그러나 본 발명이 상기 기준값(SS)에 의해 한정되는 것은 아니다. 본 발명에 따른 상기 기준값(SS)은 사용자(USR)의 임의대로 설정 및 변경될 수 있다.In the sensing information generation step (S100), at least one of the main body sensor module (MPS) and the detachable sensor module (RMS) measures body information or CPR performance information of the patient (PT) to generate sensing information. A measured value of the inertial sensor at an initial point in time when a value measured by the pressure sensor becomes greater than a predetermined reference value may be set as a zero point of the inertial sensor. The preset reference value is 10

can be However, the present invention is not limited by the reference value SS. The reference value (SS) according to the present invention can be set and changed arbitrarily by the user (USR).

In the sensing information collection step (S101), the information collection unit (DC) of the control module (CM) collects the first sensing information and the second sensing information. The information collecting unit DC transmits the collected sensing information BA to the prescription value generating unit PG.

In the prescription value calculation step (S102), the prescription value generating unit (PG) of the control module (CM) receives the sensing information. The prescription value generating unit PG calculates a prescription value based on the sensing information. In the prescription value calculation step ( S102 ), the prescription value may be calculated by comparing the patient's height information among the sensing information with previously stored Broselow tape information.

In the output signal generating step (S103), the output signal generating unit (SG) generates a first output signal and a second output signal corresponding to the prescription value.

In the guide information output step (S104), at least one of the body output module (MPO) and the detachable output module (RMO) may output CPR guide information corresponding to the output signal.

In the data transmission step (S105), at least one of the sensing information, prescription value, output signal, and CPR guide information may be transmitted to an external server through a wired or wireless network.
