Which emergency technique involves mouth-to-mouth resuscitation?

Rescue breathing is the technique that specifically involves providing oxygen to an individual who is not breathing. This method entails performing mouth-to-mouth resuscitation, where one person breathes into the mouth of another to supply air directly into the lungs. The primary goal of rescue breathing is to restore normal breathing and ensure oxygen reaches the body's vital organs.

While other techniques mention components of emergency response, they do not focus exclusively on the mouth-to-mouth aspect. Airway clearance is about removing any obstructions in the airway, which might be a precursor to performing rescue breathing. Cricothyrotomy is a more advanced procedure involving an incision in the throat to secure an airway when it is otherwise obstructed, and cardiopulmonary resuscitation (CPR) combines chest compressions with rescue breaths but is not solely focused on mouth-to-mouth resuscitation. Thus, rescue breathing is the correct description of the technique involving mouth-to-mouth resuscitation.
