What is the primary objective of rescue breathing in a lifeguard situation?

The primary objective of rescue breathing in a lifeguard situation is to increase the oxygen supply to the lungs. When a person is not breathing or is breathing inadequately, their body is deprived of essential oxygen, which is crucial for sustaining life and preventing brain damage. By providing rescue breaths, the lifeguard is effectively delivering oxygen directly into the person's lungs, which helps to restore oxygen flow to the bloodstream and, subsequently, the vital organs.

This process is critical in cases of drowning or respiratory failure, where maintaining adequate oxygen levels is necessary for the person to survive until more advanced medical care can be administered. Focusing on increasing the oxygen supply ensures that the person has the best chance of recovery and avoids severe complications arising from hypoxia (lack of oxygen).
