Therapeutic Support Surface

Advanced powered mattress replacement systems and overlays offer innovative features for the ultimate in pressure relief.

Patients immobilized and unable to move can suffer serious destruction of the skin and soft body tissue in as little as one hour. This often results in the formation of a pressure ulcer. A pressure ulcer is defined as any lesion caused by unrelieved pressure resulting in underlying tissue damage. Complications related to pressure ulcers cause an estimated 60,000 deaths and cost over $1.3 billion annually. However, most pressure ulcers are treatable and even preventable. Therapeutic Support Surfaces are a proven way to help prevent and treat pressure ulcers.

Therapeutic Support Surfaces prevent and treat pressure ulcers by molding to the body to maximize contact, redistributing weight as uniformly as possible, and reducing pressure to below capillary closure.

Hospital Mattress Overlays and Therapeutic Support Surfaces:

Group I designed to aid in the prevention and treatment of pressure ulcers.
  • Gel Overlay - Uniformly distributes pressure and reduces friction and shear with gel bladders inside a foam core. Designed to be placed directly of an existing mattress.
  • Foam Mattress - Multiple layers of foam for maximum pressure reduction. Designed to be placed directly on the existing bed frame.
  • Alternating Pressure Pad - Alternates inflation and deflation of cells to constantly change pressure points. Designed to be placed directly on top of existing mattress.
Group II for pressure ulcer therapy. Provides the therapeutic benefit of pressure relief and skin moisture management.
  • Non-Powered Pressure Reduction Mattress - Channels air through cells for maximum patient immersion.
  • Alternating Pressure Mattress - Alternates inflation and deflation of cells to constantly change pressure points and promote circulation.
  • Low Air Loss Therapy -Floats the patient on air-filled cells while circulating air across the skin to reduce moisture and help maintain a constant skin interface pressure "True Air Loss" utilizes 100-150 liters of air per minute to maintain normal skin temperature and moisture levels, yet will not dry out therapeutic dressings.
  • Lateral Rotation Mattress - Constantly rotates the patient from side to side cyclically change pressure points. Reduces risk of pulmonary complications, stimulates gastrointestinal tract, improves circulation and provides pressure relief without disturbing the patient.

In-Home Style for finding support surfaces for Full-size, Queen-size beds. This is a small category of mattress systems that fit beds other than twin-size hospital beds.

Full-framed products or specialty beds are the high end of the specialty-surface spectrum. Some require an electric pump and are used as treatment products. The three basic groups are high air loss, low air loss, and kinetic therapy. Whereas kinetic therapy beds were originally created as a skin treatment product, they are now used in the acute care setting for the treatment of pulmonary conditions and spinal fractures (ex: ROHO Dry Floatation, MATTSYSC). High and low air-loss beds have been designed to provide pressure relief for patients who may not be turned or who have Stage 3 or 4 pressure ulcers on more than one turning surface.
