Alternating / Air-Flow Mattresses (Active Surface) Also known as air-flow mattresses, alternating pressure mattresses relieve and redistribute pressure through a dynamic lying surface. The inflated air cells provide pressure to support the user whilst the deflated cells provide relief for the skin above them.
A low air loss mattress has tiny laser made air holes in its top surface which continually blow out air causing the patient to float. This reduces skin interface pressure at the mattress surface. As a result, moisture is wicked away and the patient stays dry.
