Correct cardiopulmonary resuscitation (CPR) techniques include chest compressions, opening the airway, artificial respiration, electric defibrillation, assessment and other steps.
1. Chest compressions: let the patient lie on a hard board or on the floor, the operator kneels on the patient’s right side, and presses the middle and lower third of the patient’s sternum with the root of the palm, the depth of the compression is 5-6cm, and the frequency of the compression is 100-120 times/minute. During compression, the operator should straighten both arms and press vertically with the help of gravity.
2. Open the airway: after 30 chest compressions, ventilation should be performed twice, and the secretions or dirt in the patient’s airway should be cleared before ventilation, then the administrator should press the forehead and pinch the patient’s nose with one hand, and lift the patient’s jaw with the other hand to open the airway.
3. Artificial respiration: the administrator inhales deeply and then exhales forcefully after his mouth is completely wrapped around the patient’s mouth, and the delivery time should be more than 1 second to ensure that the chest is seen to rise and fall.
4. Defibrillation: If there is an AED nearby or in the hospital, defibrillate as soon as possible. Resume chest compressions as soon as possible after defibrillation.
5. Assessment: After five cycles of CPR (30 compressions + 2 artificial respirations = one cycle), determine whether the heart rhythm and respiration are restored.
The above operation process should be standardized to avoid ineffective CPR and other accidents.
