What technique is recommended if head or neck trauma is suspected during CPR?

The use of a jaw-thrust maneuver is the recommended technique when head or neck trauma is suspected during CPR. This method is crucial because it helps to open the airway without moving the cervical spine, which could potentially exacerbate any existing injuries. By moving the jaw forward, it maintains airway patency while minimizing the risk of further injury to the spinal cord.

In contrast, a chin-lift maneuver involves tilting the head back, which can lead to possible movement of the cervical spine and is therefore not appropriate in the presence of suspected spinal injuries. Abdominal thrusts, while essential for clearing a blocked airway in some situations, are not related to managing potential spinal injuries and should be approached with caution when trauma is involved. Immediate intubation may be necessary in severe situations, but it typically requires advanced skills and is not the first line when initial airway management is needed in the context of potential trauma. Hence, the jaw-thrust maneuver is the most appropriate and safest technique in this scenario.
