Artificial respiration and cardiopulmonary resuscitation

CPR is very important for patients with sudden cardiac arrest. CPR is usually performed within 4 minutes to reduce irreversible damage to the patient's brain and other human organs. CPR mainly includes two links: one is continuous chest compression, and the other is artificial respiration. The chest compression is located at the middle and lower 1/3 of the sternum. The compression frequency is 100 beats/minute, and the compression depth is 5 cm. Breathing can be done with a simple respirator or mouth-to-mouth breathing, which is 30:2 to chest compressions, which means 30 compressions and 2 breaths. CPR is one of the rescue methods that every citizen needs to master.
