Abstract:
1. A method of determining and setting pressures for a patient support including a head section and a seat section, the method comprising the steps of: measuring force exerted upon the patient support, measuring an angle that a head section of the patient support assumes relative to horizontal, calculating patient weight from the force measurement and the head section angle measurement, setting baseline pressures in the sections of the patient support in response to the calculated patient weight, re-measuring the force exerted upon the patient support, selectively adjusting the pressure in at least one of the sections of the patient support based upon the re-measured force, determining if the re-measured force is outside a defined limit, and if the re-measured force is outside the defined limit, re-setting the baseline pressures.
