Why is the head tilt chin lift procedure performed in cpr?

To open the airway

In CPR, the head tilt chin lift procedure is performed to open the airway of an unresponsive person. When a person is unresponsive, the muscles that control the jaw and tongue relax, allowing the tongue to fall back and block the airway. This can make it difficult or impossible for air to enter the lungs, leading to respiratory arrest.

The head tilt chin lift procedure opens the airway by lifting the chin and tilting the head back, which moves the tongue out of the way and allows air to flow into the lungs.

To perform the head tilt chin lift, follow these steps:

1. Place one hand on the person's forehead and the other hand under the chin.

2. Gently tilt the head back until the chin is pointing upwards.

3. Pinch the nose shut.

4. Give two rescue breaths, each lasting about one second.

Repeat the head tilt chin lift procedure and rescue breaths until the person begins breathing again or until medical help arrives.
