The steps to do CPR and artificial respiration are as follows: 1. clear the airway and lay the patient flat on a hard surface. 2. kneel next to the patient’s neck and shoulders. 3. open the patient’s airway using the head-up chin-lift method. 4. check whether the patient is breathing, and if there is no normal breathing, artificial respiration should be performed mouth-to-mouth immediately. If the patient’s mouth is dirty or not convenient for artificial respiration, it can be performed with a gauze pad. Continuous chest compressions can be very beneficial to improve the patient’s heartbeat, especially if two people are working together, one for artificial respiration and one for chest compressions. The general number of compressions is about 100 times/minute, which can make it possible to restore the patient’s vital signs in a short period of time.
