About Alternating Pressure Wheelchair Cushion Support Surfaces - Prevent and Treat Skin Breakdown.


alternating pressure therapyAlternating pressure therapy is used in wheelchair seating, mattresses, and mattress overlay to redistribute pressure and improve comfort for the prevention of pressure ulcers and the treatment of Stage I -IV pressure ulcers.
Alternating Pressure is a dynamic air-powered therapy that redistributes pressure by use of an alternating air pump through a series of air bladders within a wheelchair cushion or mattress. There are two series of air bladders in every cushion, odd series, and even series. The bladders are inflated via an adjustable alternating air pump that varies the pressure in one of the two series in a timed cycle (typically 10 minutes). This leaves one series of bladders firm and the other series soft. At the end of the time cycle, the firm bladders become soft and the soft bladders become firm. The alternating pressure cycles continue. 
There are many benefits of alternating pressure therapy in a wheelchair cushion. However, the primary benefits are: pressure redistribution and improving blood flow to the skin.

Continued pressure between the body and the seating surface closes off the vascular structures in the skin impeding blood flow. A constant supply of blood brings oxygen and nutrients to the skin and is essential for keeping the skin healthy. By impeding blood flow the skin will breakdown and eventually die, leavng a wound, The series of firm bladders that support the body change every 10 minutes. Therefore, 

To ensure the quality, durability, health, and safety of the alternating pressure support surfaces we offer, all are manufactured in the US by Blue Chip Medical Products or Crown Medical Products. from materials sourced from US manufacturers. This ensures adherence to the strictest US medical standards.
