What technique is used to open the airway in an unresponsive patient without a spinal injury?

The head-tilt, chin-lift maneuver is the preferred technique for opening the airway in an unresponsive patient when there is no suspicion of a spinal injury. This technique involves tilting the patient’s head back slightly while lifting the chin up and forward, which helps to move the tongue away from the back of the throat and clear the airway.

In cases where a patient is unresponsive, maintaining a clear airway is crucial for ensuring effective ventilation and oxygenation. The head-tilt, chin-lift is a practical and effective method, especially in situations where you can safely manipulate the airway without the risk of exacerbating a spinal injury.

Other techniques, such as the jaw-thrust maneuver, are more appropriate in cases where spinal injury is suspected. The neck extension and chest thrusts serve different purposes, primarily addressing issues like airway obstruction or different types of rescue breathing, rather than simply opening the airway. Therefore, the head-tilt, chin-lift maneuver is the most suitable approach for this scenario when spinal precautions aren't necessary.
