If a casualty is unconscious, the tongue may have relaxed, causing an airway blockage. Use the head-tilt chin-lift or jaw-thrust method to open the airway. Important note: If a neck or spinal injury is suspected, use the jaw-thrust method to open the airway.

This is the first “A” of MARCH PAWS.

NOTE: Once the airway has been opened using one of these maneuvers, the casualty may require repeated/continued maneuvers to maintain an open airway.
