What is the appropriate method for opening an unconscious person's airway?

The appropriate method for opening an unconscious person's airway is to lift the chin and tilt the head back. This technique is known as the head-tilt, chin-lift maneuver. By tilting the head backward and lifting the chin, you help to align the airway, which opens it and allows for airflow. This is particularly important because an unconscious person may have relaxed muscles in the throat, which can lead to airway obstruction. By using this method, you reduce the risk of the tongue blocking the airway and facilitate easier access for rescue breaths if needed.

In emergency situations, it is critical for first responders to ensure the airway is clear to provide adequate ventilation and oxygenation. The head-tilt, chin-lift maneuver is widely recommended and adopted in various first aid and CPR training programs, making it a fundamental skill for anyone performing these life-saving techniques.
