Abstract
Automated pressure relief mattress support system including method and apparatus for supporting a bed patient comprising an air mattress construction having a plurality of longitudinally extending flexible air compartments or tubes which are connected to a pressurized air source and uniformly pressurized to an optimum air pressure to minimize interface surface pressure between a patient and the mattress. The system is of simplified economical construction and can be operated both passively and actively to minimize patient/mattress interface pressures and to roll a patient to right and left side positions, typically to selected angles of up to about 30 degrees for preselected times, with roll position air pressure set points in the mattress air tubes for particular roll angles of the patient being automatically established, based on patient body weight.
