ABSTRACT:
A pressure sensing device includes a sensor for continuously measuring the pressure on a patient's skin at the interface between the skin and a surface exerting pressure on the skin. A monitoring device monitors the pressure exerted on the skin and the elapsed time period during which the skin has been exposed to the measured pressure. An alarm then indicates when the combination of the pressure and the elapsed time is approaching a previously determined level in order to prevent damage to the patient's skin.
