Therefore, CPR should be started without delay.
In real life, once you discover that someone has lost consciousness or their heart has stopped breathing or their heart has stopped beating due to drowning, electric shock, or sudden fainting, you must start cardiopulmonary resuscitation as soon as possible.
The CPR process cannot be interrupted. At the same time, actively seek help from others and contact 120 emergency services. Continue CPR until medical personnel take over.
The three steps of cardiopulmonary resuscitation (CAB) are: chest compressions, airway opening, and rescue breathing.
1. C: refers to chest compression, and the compression area is at the level of the line connecting the two nipples in the middle of the chest.
Overlap the bases of your palms, interlock your fingers, keep your arms taut and vertical, straighten your elbows and do not bend them, lean your upper body forward and press vertically downward with force, keep your waist straight, and the midpoint of the line connecting your shoulders directly above the pressing point.
Do it quickly, forcefully, and rhythmically, ensuring the chest cavity fully recoils.
However, be careful not to let your palms leave the chest wall. The compression depth for adults is 5-6 cm, the compression frequency is 100-120 times/minute, and the compression frequency is 30 times/cycle.
2. A: After opening the airway and clearing oral and nasal secretions, use the forehead-pressing and chin-lifting maneuver to prevent airway obstruction and prevent the tongue from falling back.
3. B: Artificial respiration. While keeping the patient's forehead depressed and chin lifted, the rescuer pinches the patient's nostrils closed with one hand, then takes a deep breath and blows quickly and forcefully into the patient's mouth. Repeat twice per cycle.
Wei Ping pointed at himself with his hands, and sometimes he would lie on the ground to demonstrate in more detail.
