What is the correct technique for giving rescue breaths?

The correct technique for giving rescue breaths involves pinching the nose shut, sealing the lips around the victim's mouth, and blowing gently into the mouth. This method ensures that air is effectively delivered into the lungs while minimizing the risk of air escaping through the nose, which could happen if the nostrils are not pinched.

By sealing the lips, the rescuer creates a complete seal that allows for effective ventilation. The gentle nature of the breaths is crucial, as it helps prevent barotrauma, which is a condition that can occur if air is forced into the lungs too rapidly or with too much pressure. This approach is designed for maximum effectiveness and safety, and it helps ensure that the breaths taken are appropriately delivered to assist the victim.

The other options compromise the effectiveness of the breaths or introduce potential risks, such as air leakage or inadequate delivery of oxygen.
