What is the preferred method of rescue breaths for an infant?

The preferred method of rescue breaths for an infant involves using a combination of mouth-to-mouth and covering the nose. This technique is beneficial because it allows for a more effective delivery of air into the infant's lungs while minimizing the loss of air through the mouth. Infants have small airways, and covering both the mouth and nose helps create a seal, ensuring that the breath is delivered efficiently.

This approach also recognizes that infants have different anatomical features compared to older children and adults, necessitating a specialized technique for respiratory support. Ensuring that both the mouth and nose are appropriately covered maximizes the chances of reoxygenating the infant effectively, which is critical in emergency situations.
