What purpose does the head tilt chin lift maneuver serve?

The head tilt-chin lift maneuver is specifically designed to open the airway by aligning the anatomical structures of the airway, which can often become obstructed due to the position of the tongue or soft tissues in unconscious or unresponsive individuals. When performed correctly, this technique helps to ensure that air can flow freely into the lungs, making it essential for basic life support and rescue breathing.

In situations where a person is unable to breathe or is experiencing airway obstruction, this maneuver is a first and crucial step in restoring an adequate airway. It is an important skill for anyone involved in first aid or emergency response, as it allows for effective ventilation and oxygenation of the patient. Other options, such as increasing heart rate or assessing consciousness, do not relate to the direct purpose of this specific maneuver.
