ABSTRACT:
An alternating pressure pad has two sets of alternately inflatable cells. The alternately inflatable cells overlie additional base cells in a lower layer of the mattress. These base cells are all simultaneously inflated whilst each of the sets of upper cells are repeatedly inflated and deflated in alternation over an inflation and deflation cycle. During a cycle each set of upper cells is deflated at least once while the patient is primarily supported by the other inflated set of cells. During each inflation and deflation cycle, the additional base cells are reduced in pressure at least once. In this way, even if a part of the patient is temporarily supported only on the lower base cells, the support pressure is temporarily reduced each cycle to minimize pressure effects on the patient.
