Final answer:
To open an airway with suspected trauma, the Jaw-Thrust Maneuver should be used to avoid further injury, especially to the spine, by moving the jaw forward without moving the neck.
Step-by-step explanation:
When opening an airway with suspected trauma, you would use the Jaw-Thrust Maneuver technique. This method involves moving the jaw forward without moving the neck, as moving the neck could potentially cause further injury if a spinal injury is suspected. The Jaw-Thrust Maneuver is preferable to the Head-Tilt-Chin-Lift Maneuver, which is used when there is no suspicion of spinal injury. It's essential to remember that maintaining an open airway is critical, but must be done with great care to avoid exacerbation of any potential spinal injuries.
