In what situation should you not perform rescue breaths during CPR?

Performing rescue breaths during CPR is not necessary if the person is breathing. In any resuscitation scenario, CPR is indicated for someone who is unresponsive and not breathing or not breathing normally. If the individual is breathing, it suggests that their respiratory function is intact, and they do not require artificial ventilation. Maintaining an open airway and monitoring their breathing is the priority in this situation, rather than initiating rescue breaths.

The other options highlight scenarios where rescue breaths would be relevant or necessary. For instance, if a person is choking, they may need assistance to clear the airway instead of rescue breaths. Similarly, different protocols exist for infants versus adults, and unconscious individuals who are breathing still require careful monitoring and can benefit from rescue breaths, particularly if they also exhibit signs of ineffective breathing.
