Support surface

Support surface is a specialized device for pressure redistribution designed for management of tissue loads, micro-climate, and other therapeutic functions (i.e., any medical device that a person lies or sits on for therapeutic purposes). The term is often used in the context of pressure ulcer prevention and treatment.

Types of Support Surfaces

There are three main types of support surfaces: reactive support surfaces, active support surfaces, and integrated bed systems.

Reactive Support Surfaces

Reactive support surfaces are non-powered and respond to the patient's movement. They include foam mattresses, air-filled mattresses, and gel-filled mattresses. These surfaces are designed to redistribute pressure by increasing the surface area over which the patient's weight is distributed.

Active Support Surfaces

Active support surfaces, also known as powered surfaces, have an external source of energy and can change their load distribution properties with or without the patient's movement. They include alternating pressure mattresses, low air loss mattresses, and air fluidized beds.

Integrated Bed Systems

Integrated bed systems are bed frames and support surfaces that are combined into a single unit. They are designed to reduce the risk of pressure ulcers and to provide other therapeutic features such as patient turning and percussion and vibration for pulmonary therapy.

Clinical Applications

Support surfaces are used in a variety of clinical settings, including hospitals, long-term care facilities, and home care. They are used for patients who are at risk of developing pressure ulcers, as well as for patients who already have pressure ulcers. The choice of support surface depends on the patient's clinical condition, the type and stage of the pressure ulcer, and the care setting.
