How many initial rescue breaths should be given to an adult upon contact with an unresponsive drowning victim?

In the case of an unresponsive drowning victim, the recommended number of initial rescue breaths is 2. When a rescuer arrives at the scene and identifies that an adult is unresponsive due to drowning, they should administer 2 rescue breaths before proceeding with chest compressions or further resuscitation efforts. This approach is grounded in the importance of providing oxygen to the victim, as drowning often leads to a lack of oxygen, necessitating immediate ventilation.

In emergency response protocols, giving these initial breaths quickly helps to establish a minimal level of circulation and oxygenation, which is crucial for the chances of recovery. The focus is on rapid assessment and intervention, rather than administering an excessive number of breaths, which could be less effective and delay essential chest compressions. Therefore, 2 breaths is the appropriate and crucial action in this life-saving scenario.
