What technique is used to clear the airway in CPR?

The chin lift technique is used to open the airway during CPR and is essential for ensuring that air can flow into the lungs effectively. In a situation where a person is unresponsive or needs assistance with breathing, the chin lift involves tilting the head back gently while elevating the chin, which helps to lift the tongue and clear any obstruction that may block the airway.

This technique is particularly effective because it helps to create a straight line from the mouth to the lungs, facilitating easier ventilation. It's a standard approach in basic life support training and is recommended because it minimizes the risk of further airway obstruction compared to other techniques.

The other methods listed serve different purposes or are used in different contexts. For example, the jaw thrust is another airway management technique used specifically when a spinal injury is suspected. The Heimlich maneuver is used for choking situations to expel a foreign object from the airway, and a nose pinch can be applied for different medical scenarios, such as controlling nosebleeds, but is not relevant to clearing the airway during CPR.
