In an emergency, who should provide rescue breathing?

• A. The individual with the most trained experience
• B. A bystander who arrives first
• C. The coach on site
• D. The least trained assistant

Answer: (A)

Rescue breathing is a skilled task that requires proper technique and airway management. The person with the most training is best equipped to deliver breaths safely and effectively—ensuring the airway is open, applying a correct seal if using a barrier device or mouth-to-mouth, and delivering breaths at the right rate and volume. This rescuer can also monitor ventilation effectiveness and coordinate with others who may be providing chest compressions or calling for help, without delaying care. A bystander or less-trained person may struggle with technique, risking ineffective ventilation or airway issues, while the most trained individual can lead the rescue with confidence.
