It is not feasible to do artificial respiration underwater when drowning. It is recommended to pull the patient to the shore, then artificial respiration, open the airway, remove the mouth and nose foreign body, mouth-to-nose or nasal artificial respiration can be performed. If the rescuer can hold out the drowning head out of the water, in the water that mouth-to-mouth artificial respiration, the patient’s heart, brain and lung resuscitation are of great significance. If the drowning person still has a heartbeat and more rhythmic, you can also simply do artificial respiration. If the heartbeat has also stopped, chest compressions should be done at the same time as artificial respiration. The correct location of chest cardiac compressions should be at the junction of the upper 2/3 and lower 1/3 of the sternum, and the rescuer should place the palm root of the palm on the above compression site, and the other palm should be crossed and overlapped on the back of the palm, and the fingers should not be pressed on the patient’s chest, and the two elbows should be straightened when pressing, and the back of the shoulder should be used to press the sternum vertically downward about 3-4cm, and then relax, but the palm root should not leave the chest wall, and the number of compressions should be 100 times / minute, the ratio of chest compressions to artificial respiration is 15:2, that is, 15 times of continuous compressions, and then 2 times of artificial respiration. During CPR, attention should also be paid to protecting the cervical spine, avoiding neck hyperextension, hyperflexion and rotation activities. Those whose heartbeat and respiration are not restored after short-term resuscitation should not be given up easily, and resuscitation should be continued on the way to the hospital.
