The steps of manual CPR include cardiac compression, airway patency, and artificial respiration.
After finding patients with sudden cardiac death, we should quickly assess the condition, by calling out to the patient, touching the carotid artery pulsation, and observing the patient’s breathing to quickly assess the condition, and for the patients with clear cardiogenic sudden death, we should quickly carry out cardiopulmonary resuscitation.
1. Cardiac compression: place the patient on a hardboard bed, put both hands on both sides of the patient, expose the patient’s chest, press the patient’s middle and lower 1/3 of the sternum with both hands vertically, the amplitude of the pressure should reach 5 centimeters, and the frequency of the pressure should not be less than 100 times per minute.
2. Smooth the airway: after 30 times of pressure, smooth the patient’s airway, remove foreign objects in the mouth, press the patient’s forehead, make the airway completely open, cervical spine injury patients should use both hands to lift their jaws, to avoid causing cervical spine injury.
3. Artificial respiration: the rescuer’s mouth is completely wrapped around the patient’s mouth, mouth-to-mouth artificial respiration, blowing the amount of gas mastered in 500 ml or so, to avoid over-ventilation, blowing the nose pinch, and then let go. The ratio of compression to ventilation is 30:2.
Cardiac compression can be performed in cycles, and the patient’s condition is judged after every 5 cycles to understand the effect of cardiac compression.
