Patient support surface index control
First Claim
1. A person support surface comprisingat least one inflatable bladder,a cover including a portion above the at least one inflatable bladder, anda control system including a plurality of sensors that generate data signals indicative of a characteristic of the at least one inflatable bladder and a person'"'"'s tissue contacting the cover, a processor operatively coupled to the plurality of sensors, the processor being configured to execute operating logic to determine a surface performance index as a function of the data signals, and a fluid supply coupled to the at least one inflatable bladder, the processor controlling the operation of the fluid supply as a function of the surface performance index by adjusting at least two of a temperature, humidity, and flow rate of the fluid supplied by the fluid supply.

Abstract
A control system of a patient support surface calculates a surface performance index as a function of pressure and shear. The control system also receives information from an electronic medical record (EMR) corresponding to a person'"'"'s susceptibility of developing at least one of a pressure ulcer and a superficial lesion and adjusts at least one of a component and a characteristic of the person support surface based on the information.
