The operator of the low air loss bed defines the pressures in individual air bags corresponding to each of three positions to which the patient is rotated. The pressures are maintained by a feedback control system which actuates valves connecting the gas source to separate sets of air bags. The three positions to be sequentially attained thereby causing controlled oscillation of the patient from one side of the bed frame to the other. Because each rotation position corresponds to operator defined pressures, the oscillation is customized for individuals of different body weights.
