First aid for an unconscious adult who has choked includes the following:
The chest compressions of CPR can cause vomiting, injuries to internal organs, or broken ribs. Vomiting can be a problem if the vomit is caught in the airway and inhaled into the lungs. There is a possibility that none of the procedures may work, and the person may still choke, remain unconscious, or even die.
It is important to obtain medical care from a healthcare professional. Occasionally, an object will enter the lung instead of being expelled. This can cause coughing, wheezing, or aspiration pneumonia.
