What is the preferred technique for giving rescue breaths to an infant?

The preferred technique for giving rescue breaths to an infant is mouth to mouth and nose. This approach is recommended because an infant's airway is small and more delicate compared to an adult's. By covering both the mouth and nose, the rescuer ensures that air is directed effectively into the lungs without excessive pressure, which could potentially harm the infant. This method allows rescuers to provide the necessary oxygen while being mindful of the infant's anatomical differences, ensuring that breaths are administered gently and effectively.

While other techniques, like bag-mask ventilation, can be used in certain circumstances, it might not be as practical for a lone rescuer without the appropriate equipment or training. Mouth to mouth or mouth to nose alone may not provide adequate ventilation since the mouth of an infant is smaller and might not seal properly, risking air escaping. Therefore, combining both the mouth and nose allows for a more complete and safe delivery of rescue breaths.
