Final answer:
The preferred method for opening the airway in a patient with a suspected spinal injury is the jaw thrust maneuver, which avoids movement of the spine. For more serious cases, medical professionals may resort to endotracheal intubation.
Step-by-step explanation:
The preferred method for opening the airway in patients suspected of having a spinal injury is the jaw thrust maneuver. Unlike the head-tilt chin-lift method, the jaw thrust does not require movement of the cervical spine, which is crucial for preventing any additional damage to a spinal injury.
The jaw thrust maneuver involves lifting the lower jaw with both hands, one on each side, displacing the jaw forward, and in some cases lifting the tongue as well, which can open up the airway without moving the head or neck. If the person is unresponsive or there is a risk of aspiration, which may be indicated by an obstruction in the respiratory system, more advanced airway management such as endotracheal intubation may be necessary, according to medical professionals.
