What is the proper technique to perform rescue breaths?

The correct technique for performing rescue breaths involves sealing the victim's mouth, pinching the nose to prevent air from escaping, and delivering air into the mouth over a period of one second. This approach ensures that the breath enters the lungs effectively while minimizing the risk of air escaping or causing injury.

By pinching the victim's nose, the rescuer helps maintain a closed airway, enhancing the effectiveness of the breaths given. The one-second duration for each breath allows enough time for the air to fill the lungs without causing excessive pressure that could lead to complications. This method is aligned with established guidelines for ensuring that rescue breaths are administered safely and effectively.

In contrast, other techniques mentioned may compromise the rescuer's ability to deliver oxygen to the victim efficiently or could pose risks of aspiration or other complications. For example, covering both the nose and mouth tightly may restrict airflow and create discomfort. Blowing quickly into the mouth without proper sealing can lead to ineffective ventilation, as it does not account for the need to control the airway properly. Delivering breaths every five seconds is generally appropriate for advanced resuscitation but does not pertain to the immediate technique of delivering rescue breaths.
