What should be the focus when performing rescue breaths in any victim?

The focus when performing rescue breaths is to ensure the airway is clear. This is crucial because an obstructed airway can prevent the delivery of effective breaths. If the airway is blocked by the tongue, foreign objects, or other hindrances, the breaths will not reach the lungs, rendering the rescue effort ineffective.

Clearing the airway allows for the delivery of oxygen directly into the lungs, which is essential for reviving someone who is not breathing or is in respiratory distress. Without a clear airway, the other factors related to the delivery of breaths, such as their forcefulness or rhythm, become irrelevant since the breaths will not be able to provide any benefit. Thus, ensuring the airway is clear is the foundational step that must be prioritized in providing rescue breaths.
