The proper steps and procedure for CPR are, in order, chest compressions, opening the airway, and artificial respiration.
In the initial stages of cardiac arrest, oxygen is usually still present in the patient’s lungs and blood. Starting chest compressions as early as possible helps to establish blood circulation as soon as possible and bring oxygen to the brain and heart. Pressure is applied to the intersection of the patient’s chest and the line between the two nipples, 100 to 120 times/minute.
Maintaining the airway is usually a prerequisite for artificial respiration, which needs to be preceded by the removal of foreign bodies from the airway. The simplest and most effective method is the head-back method, and in the case of cervical spine or spinal cord injury, the jaw-support method can be used.
Finally, artificial respiration, mouth-to-mouth artificial respiration is most suitable for pre-hospital resuscitation. One hand to let the patient’s head back, and pinch its nostrils, closed, the other hand on the back of the patient’s neck upward lifting, after a deep inhalation, aimed at the patient’s mouth blowing forcefully, each time the blowing time should be greater than 1 second, blowing immediately after the mouth to move away. While performing artificial respiration, it is also necessary to maintain chest compressions.
These are the correct steps and procedures of CPR.
