Alternating Pressure Mattresses
Alternating pressure mattresses work on a simple, but ingenious principle.
The mattress is composed of several air cells, or bladders. These cells inflate and deflate on a timed schedule, thereby alternating where pressure points occur on the body.
When the cell under the patient deflates, that body part is relieved of any pressure, allowing for increased blood flow. The pressure is transferred to the parts of the body resting on inflated cells. As the cycle of inflation and deflation is carried out, no body part experiences too much pressure for too long.
Relieving that pressure is the key to treating and preventing pressure ulcers, or bedsores. With regular “breaks” from the natural pressure that gravity exerts on the body, the skin has a chance to breathe, blood has a chance to flow, and pressure ulcers are avoided and healed.
