You just gave 30 compressions to an unconscious choking adult. you checked the mouth and didn't see any obvious object that could be swept clear. you opened the airway and attempted a breath. no air went in. what should you do next?

reposition the airway and attempt another breath.

Explanation:

Breathing is a fundamental action for the survival of the organism, so its maintenance is a fundamental point in any first aid procedure. After six minutes of breathing interruption, the brain can have irreversible lesions, and with ten minutes of interruption, brain death will certainly occur. For this reason it is necessary to act fast when a person has a respiratory arrest.

If a breathing arrest situation gives you 30 compressions to a choked unconscious adult and has not worked, and you have not found any object in your mouth that may have prevented breathing, you should open the patient's airway and try to blow. If air has not entered it is likely that the patient is in an inadequate position, in which case you should reposition the airway and try another breath.
