Abstract
A pressure controlled inflatable pad for supporting the body of a patient including a source of inflating fluid which provides a flow of fluid to inflate the pad through a fluid supply line. As the fluid flows through the fluid supply line, it passes through a sensor located beneath the pad to reduce fluid flow to an exhaust if the pad is insufficiently inflated to support the patient's body.
