Which of the following indicates an effective airway position in an unresponsive patient?

The head tilt, chin lift maneuver is considered an effective airway position for an unresponsive patient because it helps to open the airway by repositioning the structures of the neck and throat. When a patient is unresponsive, the tongue can fall back and obstruct the airway. By tilting the head back and lifting the chin, the airway is straightened, allowing for better airflow to the lungs.

This position is particularly useful in a situation where spinal injury is unlikely, as it provides a simple and effective way to manage airway obstruction due to the tongue or soft tissue. It is a common maneuver taught in basic life support and emergency response training, making it essential for EMRs to know and apply.

Other positions, such as the jaw thrust, are also appropriate in specific circumstances, particularly if spinal injuries are suspected. However, the head tilt, chin lift is widely recognized for its simplicity and effectiveness in securing the airway of an unresponsive patient. Other options like sitting or side-lying positions may not effectively maintain an open airway in unresponsive individuals.
