Abstract
The support and retention includes an upper back supporting portion spaced in part at least from the base providing a clearance opening for insertion of a mechanical compressor platform without requiring movement of the patient. Preferably, the clearance opens to both sides to permit insertion of the platform from either side and the upper portion is also preferably saddle-shaped and inclined upwardly to permit downward sloping of the head to provide patency of the breathing canal.
