8. The cardiopulmonary resuscitation simulation training method using the escape course-based cardiopulmonary resuscitation simulation training system according to claim 7, comprising the steps of:
s1: the cardiopulmonary resuscitation model (10) is placed in a correct position, and is placed on the back and on a firm plane;
s2: pressing the chest, namely forward inclining the upper half body, straightening the two arms, overlapping the palm root positions of the two hands and pressing the position of a pressing pump (101), pressing the chest vertically downwards for a plurality of times at the speed of 100-120 times/minute, wherein the pressing depth is 5-6cm, and the clearance of each pressing action enables the thorax to be fully rebounded;
s3: artificial respiration, comprising:
S31: the palm of one hand presses the forehead of the cardiopulmonary resuscitation model (10), the two fingers of the other hand slightly support the lower forehead, and the chin is lifted by the head, so that the connecting line of the farthest point of the occiput and the central point of the tongue (103) is vertical to the horizontal plane;
s32: keeping the state of lifting the chin by looking up the head, pinching the nasal alar part of the cardiopulmonary resuscitation model (10) by the thumb and the forefinger of the hand pressing the forehead, blowing air inwards for a plurality of times from the mouth part of the cardiopulmonary resuscitation model (10), loosening the nasal alar part at the interval of each blowing action, and pinching the nasal alar part during blowing;
S4: repeating S2 and S3, pressing and blowing in S2 and S3 at a ratio of 30: 2 is repeated.
9. the cardiopulmonary resuscitation simulation training method based on an escape course according to claim 8, wherein during the compression at S2, the distance sensor (12) collects the information of the distance between the chest and back of the cardiopulmonary resuscitation model (10) and feeds back the information to the CPU (2), and the pressure sensor (11) feeds back a signal to the CPU (2) when being triggered, and the light sensor (14) feeds back a resistance signal to the CPU (2).
10. the cardiopulmonary resuscitation simulation training method based on an escape course according to claim 8, wherein in S3, the air pressure sensor (13) collects the air pressure information in the chest cavity of the cardiopulmonary resuscitation model (10) at any time and feeds the information back to the CPU (2).
