Claim 6:
7. The method according to claim 1, wherein:
said mattress includes a zone with a plurality of bladders, the plurality of bladders including the bladder, and said method of testing includes testing the zone with the plurality of bladders;
said pressurizing includes pressuring the zone with the plurality of bladders to a first pressure with the control system of the patient support;
said sensing includes sensing, with the sensor, when the zone with the plurality of bladders has reached the first pressure;
said measuring a second pressure includes measuring, with the sensor, a second pressure of the zone with the plurality of bladders;
said measuring a third pressure includes measuring a third pressure with the sensor at the end of the fourth time period, the third pressure representing a reduced pressure from the second pressure of the zone with the plurality of bladders;
said determining includes determining a rate of change between the second pressure and the third pressure in the zone with the plurality of bladders over the fourth time period;
said comparing includes comparing the rate of change to a stored value to determine whether there is a leak in the zone with the plurality of bladders; and
said generating includes generating the second signal when the rate of change is greater than the stored value indicating a leak in the zone with the plurality of bladders.
