When is it appropriate to use a rescue breath during a rescue?

Using a rescue breath is appropriate when the diver is unresponsive and not breathing. This situation indicates that the diver may be in a state of respiratory failure, and immediate action is required to restore oxygen to the body. The primary goal of administering rescue breaths is to provide ventilatory support until normal breathing resumes or emergency medical assistance arrives.

Delivering rescue breaths helps prevent irreversible brain damage and other complications that can occur from lack of oxygen. It is essential to ensure that the airway is clear before administering these breaths, allowing for effective oxygen delivery. In this critical scenario, acting promptly and effectively can be lifesaving.

In contrast, the other situations do not warrant the immediate use of rescue breaths. For instance, if a diver is panicking underwater, the focus should be on calming and assisting them to the surface rather than performing rescue breaths. Similarly, if the rescuer feels the need to breathe or if the diver shows signs of distress but is still breathing, different actions should be taken that prioritize safety and communication rather than administering breaths.
