What should be done if a patient vomits during rescue breathing?

If a patient vomits during rescue breathing, it is crucial to clear the airway before resuming breaths. This action ensures that the airway is free from any obstruction caused by vomit, which can limit effective ventilation and increase the risk of aspiration. Once the airway is cleared, you can safely continue providing rescue breaths.

Continuing without interruption may risk choking the patient, as vomit can block the airway. Tilting the patient to one side is a common maneuver to help clear secretions or fluids, but it is not sufficient on its own; the airway must also be checked and cleared thoroughly. While calling emergency services is essential in an emergency scenario, it does not directly address the immediate need to manage the airway during rescue breathing. Thus, clearing the airway before resuming breaths is the most appropriate response in this situation.
