Which maneuver is used to open the airway in an unconscious patient?

The head-tilt/chin-lift maneuver is the recommended technique for opening the airway in an unconscious patient, particularly when there is no suspicion of spinal injury. This technique involves tilting the patient's head back slightly and lifting the chin upwards, which helps to reposition the airway and allows for better airflow. It works by removing any potential obstructions that may be blocking the airway, such as the tongue, which can fall back into the throat when a person is unconscious.

In situations where the airway needs to be secured quickly, this maneuver is effective and straightforward for individuals who are trained in first aid or emergency response. It is important to note that this method is not suitable for patients who may have a spinal injury, as it can exacerbate any existing damage. For such cases, the jaw thrust maneuver is preferred, as it does not require any head movement.

Additionally, other options mentioned, like the scoop and roll maneuver and logroll maneuver, are generally techniques for moving patients safely rather than specifically for opening the airway. Thus, the head-tilt/chin-lift remains the primary choice in most scenarios involving unconscious patients without spinal concerns.
