Abstract
A person support apparatus, such as a bed, cot, stretcher, or the like, for a supporting an occupant includes an exit detection system that has, in some embodiments, multiple user-selectable zones. An alert is triggered when the occupant crosses a boundary of the selected zone. A first zone has a boundary that is adjusted based on a condition of the person support apparatus, such as the width of the support deck or other characteristic. A second zone has a boundary that is not adjusted based on the condition of the person support apparatus, but which may have a boundary that is dependent on an initial location of the occupant when the exit detection system is armed. The initial location of the occupant may correspond to a center of gravity of the occupant.
