Alternating-pressure bed mattress overlay, single-use
Definition
A pad or thin mattress, usually full-body length, which is placed on top of a bed mattress and designed with parallel chambers that are alternately filled with forced-air to actively change an occupant's bed contact points, typically to relieve pressure points for comfort and to prevent pressure sores. It is commonly used for elderly immobilized (especially in cases of decubitus ulcers), patients with disabilities, or patients with low body fat. This is a single-use device.
