Abstract

An alternating pressure pad which comprises at least two sets (1, 2) of inflatable cells, an air supply line (7a, 7b) to each set, a pump (8) to circulate pressurised air through a circuit including the sets of cells and to return air from the cells to the pump, valve means (6) for alternately causing inflation and deflation of each set, a sensor pad (3) in said circuit through which pressurised air is passed and detecting means (17) for detecting a reduction in air flow through the sensor pad which is below a predetermined level and for increasing air pressure in said sets of cells to restore the air flow above said predetermined level.
