How to perform artificial respiration artificial respiration is to use artificial methods to help patients breathe, the most common artificial respiration method is to take mouth-to-mouth artificial respiration. 1, mouth-to-mouth artificial respiration (1) place one hand on the forehead of the injured patient, press down, so that the head is tilted back, while keeping the airway open, the thumb and index finger of the hand pressing the forehead pinch the bilateral nostrils, and the index finger and thumb of the other hand are placed on the lower jaw, lifting it upward. (2) Take a breath, tightly wrap the patient’s lips around the mouth, blow smoothly, taking care not to leak, and blow the gas into the patient’s mouth to the lungs under the operation of keeping the airway open. If the blowing is effective, the chest of the injured patient will puff up and drop as the gas is expelled. (3) After blowing, the lips of the mouth are left and the fingers pinching the nose are released to allow the gas to be exhaled. At the same time, turn the head sideways to inhale fresh air, and then perform a second blow. (4) blow into the lungs, blowing time: 2 seconds for adults, 1 second to 1½ seconds for children. Each blowing volume: 700-1100ml, average 900ml. frequency: 12 times / min for adults, 20-40 times / min for children, the younger the frequency, the higher the age. 2, mouth-to-mouth nasal artificial respiration infants are small, blowing must be sealed with the mouth of the baby’s mouth and nose for 1-1.5 seconds. 3, mouth-to-nose artificial respiration In severe trauma to the oral cavity, when the teeth are tightly closed, mouth-to-nose artificial respiration can be used. Method: Seal the injured person’s nostrils with the mouth and close his lips tightly with the hand, blow and then release his mouth to make the air exhale. 4, using a mask The chance of infectious disease through artificial respiration is rare, but for hygienic and psychological reasons, plastic masks or mouth and face shields can be used for artificial respiration. If there is no spare mask, do not hesitate to perform artificial respiration immediately.
