On-site cardiopulmonary resuscitation primary life-saving operation procedures include

The main life-saving operation procedures of on-site cardiopulmonary resuscitation include judging whether there is a pulse, chest compressions, clearing the respiratory tract and artificial respiration.

1, judge whether there is a pulse.

Pulse is generally judged by the doctor touching the pulse of radial artery with his finger, or the pulse of femoral artery and carotid artery.

2. Chest compressions

Traditionally, chest compression is a "heart pumping mechanism", that is, when chest compression is performed, the heart is squeezed between the sternum and the spine, which makes the left and right ventricles compressed and the blood is pumped out; After relaxing the compression, the ventricle relaxes and the blood returns to the heart.

Step 3 clean the respiratory tract

The three methods of clearing the respiratory tract refer to the methods of raising the head and lifting the jaw, raising the head and lifting the jaw, and lifting the jaw with both hands. They are mainly used for the treatment of tongue coating, which can effectively clear the airway and avoid the airway patency caused by tongue coating falling off.

4. artificial respiration

Artificial respiration is the first aid method when spontaneous breathing stops. Air enters the lungs rhythmically through bare hands or mechanical devices, and then the gas entering the lungs is exhaled through the elastic retraction force of the chest and lung tissue. This cycle, rather than spontaneous breathing.

Matters needing attention in cardiopulmonary resuscitation

When it is found that the patient is unconscious, stops breathing, the pulse and heart sounds disappear, and the blood pressure cannot be heard, a decision should be made quickly, and chest compressions and artificial respiration should be performed immediately. Don't miss the most precious rescue opportunity by repeatedly measuring blood pressure, changing sphygmomanometer, asking others to check, waiting for other doctors to diagnose, and waiting for ECG examination.
