Alternating Pressure Mattresses are designed to be used by bed ridden patients who have lost the ability to move in bed, change their resting position or with lowered mental awareness level. Alternating Pressure Mattresses consist of individual air tubes that automatically inflate and deflate on a set schedule which changes the pressures on a given point on the body, enhancing tissue perfusion by increasing blood flow through capillaries as pressure is applied and released. Alternating Pressure Mattresses greatly lower the risk of pressure sores or bed sores. Alternating Pressure Mattresses can prevent or help heal decubitus ulcers, commonly called 'bedsores' or 'pressure sores' and provide comfort to patients with burns, Multiple Sclerosis, Lou Gehrig's disease, Fibromyalgia, etc.
