The correct technique when applying compressions mainly involves grasping the correct site of compression, the amplitude of compression, and the frequency of compression.
Cardiopulmonary resuscitation, abbreviated as CPR, is a life-saving technique for cardiac and respiratory arrest, which aims to restore the patient’s voluntary circulation and breathing.
After determining that the patient has lost consciousness and voluntary heartbeat, assess whether the scene environment is safe and call for an ambulance. Prepare for chest compressions by placing the patient in the prone position on a hard board bed.
The correct technique is to attach the root of the palm of one hand to the middle and lower 1/3 of the patient’s sternum, the root of the palm of the other hand is superimposed on the root of the palm of the patient’s sternum, the arms are perpendicular, and vertical downward pressure is applied with the weight of the body, the frequency of the compression is 100~120 times/minute, and the depth of the compression is 5~6 cm. After each compression, the root of the palm cannot leave the thorax, and the thorax is allowed to rebound automatically, and the time between compression and relaxation is 1:1.
In the case of pediatric patients, press the sternum with one or both hands at the level of the nipple line. In infants, press the sternum horizontally with two fingers immediately below the nipple line.
After compression, open the airway, clear the mouth of foreign objects and dentures, and perform artificial respiration using a compression ventilation ratio of 30:2. Cycle through the above operations until professional rescuers arrive.
Cardiopulmonary resuscitation (CPR) is an effective way to save a patient’s life before the arrival of 120 and specialized emergency equipment. If treated promptly, cardiac arrest patients may be saved and recover. First aid professionals need to be systematically learned to avoid serious consequences.
