How should rescue breaths be administered to an infant?

To administer rescue breaths to an infant, it is essential to provide effective ventilation in a safe and controlled manner. The correct method involves using your mouth to cover both the infant’s mouth and nose. This technique ensures that an adequate seal is created, allowing for proper delivery of air into the lungs.

When performing this procedure, it’s crucial to blow gently into the infant’s mouth and nose to avoid causing injury or excessive air pressure. The infant's chest should visibly rise with each breath. The other methods listed do not facilitate the appropriate delivery of rescue breaths. Using a breathing mask may not provide the correct fit for an infant, and puffing air from a distance can lead to ineffective ventilation, as it does not create the necessary seal. Additionally, administering breaths through a tube is not standard in basic life support for infants, as this approach would typically be reserved for more advanced medical care in a hospital setting.
