A pneumatically controlled intubation mat includes laryngoscope-mounted controls. A body supporting mat is positioned beneath the patient undergoing endotracheal intubation and is dimensioned to extend beneath the patient's torso and head while in a substantially upward-facing prone position. An inflatable bladder is positioned between the base and the mat board which is adapted to elevate the mat board with respect to the base as the bladder is inflated and thereby expands. An expandable headrest is affixed to a top surface of the mat board and is positioned for placement beneath the patient's head. The headrest further includes a head support air bladder which is operative to elevate the patient's head as the head support bladder is inflated and the headrest thereby expands. A source of compressed air is in fluid communication with the torso support bladder and the head support bladder by way of an air distribution manifold. The valve means on the air distribution manifold selectively conduct pressurized air from the source to the torso support bladder and the head support bladder whereby the patient's torso/head position may be altered to achieve optimal anatomical alignment of the patient's larynx for intubation. The valve means are preferably electromechanical valves which are actuated by thumbswitches located on a housing which is snap-fit to the top of the intubation handle.
