CPR does not press on the breasts. Cardiopulmonary resuscitation compression site is the location of the middle and lower 1/3 of the sternum, but there is no clear line of demarcation in the location of the middle and lower 1/3 of the body surface, generally to the line between the two nipples and the junction of the sternum in the middle of the sternum as the compression point, the compressor puts the palm of the hand between the two nipples and the sternum in the middle of the sternum on the sternum. Usually, the root of the palm of the left hand is placed in the position of the pressure point, then the two hands are crossed, the fingers are interlocked, the fingers are lifted upward, and the process of pressure is kept in the vertical state of the upper limbs, and the pressure is pressed vertically downward with the pressure of the upper body. Cardiopulmonary resuscitation (CPR) is a life-saving technique for cardiac and respiratory arrest. If correct and effective resuscitation measures are taken in a timely manner, it is possible to save the patient’s life.
