When performing mouth-to-nose ventilation on an infant, what is the primary action to create a seal?

In the context of performing mouth-to-nose ventilation on an infant, the primary action to create an effective seal is to place the mouth over both the mouth and the nose of the infant. This technique ensures that air can be delivered effectively to the infant’s lungs without escaping.

Infants have smaller airways, and their facial structures require that both the mouth and nose be covered to ensure proper ventilation. This method maximizes the effectiveness of the rescue breaths by directing the airflow into the lungs rather than allowing it to escape, which might happen if only one area is covered. This is particularly crucial during emergencies when the aim is to provide adequate oxygenation quickly and efficiently.

Additionally, when sealing around both the mouth and the nose, it minimizes the risk of air leaks that could compromise the ventilation process. It’s vital to create a good seal in these situations, as a poor seal can lead to ineffective breaths, which would not support the infant’s respiratory needs.
