Medline's Aero-Pulse  and pad effectively cushion the body against pressure with a multitude of air tubes that alternately fill and empty. The pad, made of extra durable 16-gauge vinyl, lasts longer than standard APP pads on the market. Special embossing helps prevent the Aero-Pulse pad from sliding off the bed during use and gives your patients more air circulation to minimize heat build-up. A vital system component, is engineered for reliable, trouble-free use. It operates quietly so patients are not disturbed; a lighted on/off switch signals the nurse that the unit is operating.
