Artificial respiration and chest compressions each play an important role in cardiopulmonary resuscitation (CPR). They complement each other rather than replace each other.

The main function of artificial respiration is to help people with respiratory arrest get enough oxygen to sustain life. By utilizing the principle of the pressure difference between intrapulmonary pressure and atmospheric pressure, artificial respiration can maintain the most basic life conditions of respiratory arrest victims, relieve suffocation, respiratory muscle paralysis, and correct cardiac arrest. Artificial respiration is an important part of cardiopulmonary resuscitation operations, which can maintain normal respiratory function and avoid respiratory arrest.

The main function of chest compressions is to increase the pressure on the chest, directly compress the heart to generate blood flow, make the heart contract and relax, and pump more blood into the heart. In addition, chest compressions can also cause the lungs to contract, promote repeated ventilation of the lungs, and help gradually recover from shock. In emergency situations of cardiac arrest or respiratory arrest, chest compressions can save lives.

However, purely from the perspective of first aid success rate, chest compressions may be slightly higher than artificial respiration in some cases. But this does not mean that artificial respiration is not important. Both are indispensable in CPR.

Therefore, which is more effective is not a simple answer but depends on the patient's specific condition and the first responder's skills and experience. In an emergency, the correct approach is to perform CPR as soon as possible, including artificial respiration and chest compressions, and at the same time call the emergency phone to seek help from professional medical staff. In daily life, the public should receive professional first aid training so that they can provide correct and effective treatment in emergencie
