Use of CPR

CPR can maintain the patient's vital signs through simple first aid measures and enable the patient to receive better treatment when professional medical rescue is not available and first aid is provided in a short time. General situations where CPR is appropriate include:

Cardiac arrest: refers to the heart stopping beating and being unable to deliver oxygen and nutrients to various tissues and organs of the body. At this time, CPR should be performed immediately.

Sudden cardiac death: refers to the sudden interruption of the blood supply to the heart, causing cardiac arrest. Symptoms include sudden collapse, no pulse and no breathing.

Drowning: Water flowing into the lungs can prevent the inhalation of oxygen, causing loss of consciousness and cardiac arrest.

Asphyxia: mainly caused by airway obstruction or lack of oxygen, which may lead to cardiac arrest

Electric shock or electrocution accident: may cause cardiac arrest

In short, various causes of cardiac arrest require timely CPR.

For cardiac arrest, call an ambulance or medical personnel first. At the same time, when it is determined that the patient is not breathing, unconscious and has no pulse or heartbeat, CPR should be started immediately.

Lie the patient flat on a hard, stable surface, use a CPR mouthpiece/mask to provide oxygen, and then perform chest compressions. The basic steps of CPR are to first perform 30 chest compressions, then take 2 breaths (mouth to mouth or mouth to nose, blowing to open the airway), then continue to perform 30 chest compressions, and then take 2 breaths , and so on.

Note that when performing chest compressions, you need to master the correct technique and rhythm, use enough force to press the sternum to about 5 cm, and maintain the frequency at about 100 times/minute. During the breathing process, the patient needs to stretch and exhale before performing emergency breathing. If the patient also has trauma or possible cervical spine fractures, a C-cervical vertebrae needs to be used to fix the position of the cervical spine to prevent the cervical spine fracture from worsening.

CPR is a high-risk first aid measure that requires certain professional knowledge and skills. If you are not sure whether you can do it correctly, call emergency services and seek professional help.
