Encountered in critically ill patients, the first four points in accordance with the foregoing order to observe if there should be awareness of barriers to emergency treatment immediately.

At this point, the most horrible thing is that back off the base of the tongue respiratory obstruction (blocked nose from the air channel ) and lead to asphyxiation.

In order to prevent the occurrence of such deaths, must be addressed without delay so that the problem is the base of the tongue that do not obstruct the respiratory tract, to ensure smooth breathing. In other words, to carry out the treatment to prevent suffocation. If the patient or injured on their ear despite calling his name, but can not “hold my hand,” the sort of simple reaction time instructions, it should determine the sense of loss, should be immediately dealt with the following:

First of all, loss of consciousness, breathing, the patient should be lying-fu, head to the back.

In addition, the disappearance of consciousness and breathing all the time, do not rush to carry out artificial respiration. If the airway obstruction, and even though they carry out artificial respiration, the air also could not enter the lungs, artificial respiration is invalid.

In short, when the patient supine, patients with hand on back of the neck, the other hand (the best right-handed) according to the amount of the Department, make every effort to back plate, so that the first moment to the back.

When physicians see many patients with loss of consciousness, conditioned reflex will be to carry out such a deal.
