Method of predicting occupant egress from an occupant support based on perimeter panel status and occupant location, and a related apparatus
A method of evaluating the likelihood that an occupant will exit an occupant support comprises determining if the location of the occupant on the occupant support is displaced relative to a reference location, and if the location of the occupant is so displaced, designating that the occupant is at a risk of exiting the occupant support which is elevated relative to the baseline risk. A support apparatus comprises a framework, a mattress, sensors distributed on the support apparatus to sense occupant weight distribution on the support apparatus, and a processor adapted to designate a risk of occupant egress as a function of the direction of the occupant weight distribution and the elevation status of the perimeter panels.
1. A support apparatus comprising:
a framework having perimeter panels, the panels having an elevation status;
a mattress;
sensors distributed on the support apparatus to sense occupant weight distribution on the support apparatus; and
a processor adapted to determine occupant weight distribution relative to a reference weight distribution and to designate a risk of occupant egress as a function of:
a) occupant weight distribution, and
b) whether or not a second perimeter panel, which is adjacent to a first perimeter panel having an elevation status of DOWN, has an elevation status of UP, wherein the designation of risk also takes into account whether or not a force which is greater than a threshold force is acting on the second perimeter panel.
