In performing a jaw-thrust maneuver, which action is correct?

The jaw-thrust maneuver is a critical technique used to open a patient's airway, particularly in instances where a spinal injury is suspected. The correct approach involves using the thumbs or fingers as a lever to lift the patient's mandible forward. This technique helps to move the tongue away from the back of the throat, thereby alleviating any obstruction in the airway.

By lifting the mandible forward, the airway is opened without the need to tilt the head, which could potentially exacerbate any spine injuries. This method is particularly useful in trauma cases where spinal alignment must be preserved while ensuring that the airway remains unobstructed. The leverage action provided by the thumbs or fingers is essential to effectively manipulate the jaw without causing undue strain or movement that could worsen a potential cervical spine injury.

Other techniques mentioned, such as pushing down on the chin or pulling the jaw towards the chest, do not provide the needed airway relief and may risk compromising the cervical spine alignment. Tilting the head to one side can also lead to complications in spinal injury scenarios. Therefore, using the thumbs or fingers to lift the mandible forward is the correct, safest, and most effective method for performing a jaw-thrust maneuver.
