Cardiopulmonary resuscitation (CPR) consists of three parts: chest compressions, opening the airway, and artificial respiration. These three parts of cardiopulmonary resuscitation are indispensable and are the most important part of accomplishing cardiopulmonary resuscitation.

There are a lot of precautions to be taken during CPR, the amount of air blown in mouth-to-mouth resuscitation should not be too large, the position of chest compressions should not be wrong, the frequency of compressions should be accurate, and the ratio of chest compressions to artificial respiration should be correct.

The operation steps of CPR are as follows:

1. Judgement of consciousness; check breathing; call the emergency number and prepare first aid items; loosen the collar and trouser belt, and put them on a hard board bed or flat ground.

2, thoracic cardiac compression, the site of the two nipple line in the middle of the lower 1/3 of the sternum, the frequency of 100-120 times / min, the depth of at least 5-6 cm.

3, open the airway: tilt the head to lift the jaw method to open the airway, to remove the oral cavity of foreign bodies and dentures.

4, artificial respiration: the rescuer pinches the patient's nostrils closed with one hand, inhales y and quickly blows into the patient's mouth.

5, continued for 2 minutes of efficient CPR to cardiac compression and artificial respiration ratio of 30:2 operation.

6. Judge whether resuscitation is effective, organize the patient, and further life support.

Cardiopulmonary resuscitation, or CPR for short, is a life-saving technique adopted for cardiac and respiratory arrest. It is designed to restore a patient's voluntary breathing and voluntary circulation.In August 2020, the Red Cross Society of China and the Ministry of Education jointly issued the Circular on Further Strengthening and Improving Red Cross Work in Schools in the New Era, which incorporates students' knowledge of health and first aid, especially cardiopulmonary resuscitation (CPR), into the content of education.

Disease introduction:

Cardiac arrest refers to the sudden cessation of heartbeat caused by various reasons and in an unanticipated situation and time, which leads to the sudden suspension of the effective heart pumping function and the effective circulation, and causes severe ischemia, hypoxia, and metabolic disorders in the whole body tissues and cells, and cardiac arrest is different from the cardiac arrest of the end-stage of any chronic disease, and if correct and effective resuscitation measures are taken in time, the patient may be saved.

Once a cardiac arrest occurs, if it is not resuscitated immediately, it will cause irreversible damage to the patient's brain and other vital organs and tissues in 4 to 6 minutes, therefore, cardiopulmonary resuscitation after cardiac arrest must be carried out immediately at the scene, in order to further save the life of the patient until the cardiac arrest to save the life of the patient and to win the most precious time.
