What technique is recommended for maintaining an open airway in an adult?

The head tilt-chin lift maneuver is recommended for maintaining an open airway in an adult because it effectively lifts the tongue away from the back of the throat, which can obstruct the airway. This technique involves tilting the head back slightly while lifting the chin upward, which helps to reposition the structures in the throat and allows for better airflow. It is particularly useful in cases where the person is unresponsive or unable to maintain their own airway, as it restores patency without needing to apply pressure that might worsen an injury.

This method is commonly taught in basic life support and first aid courses as a standard practice for airway management. It is important in emergency situations to ensure that the airway is clear before proceeding with rescue breaths or other interventions, making the head tilt-chin lift a primary and effective technique.
