1. An apparatus for supporting a patient, the apparatus comprising:
- a frame, a mattress supported by the frame, and a patient position detection system including an alarm and at least one sensor, the patient position detection system being configured to detect a position of the patient relative to the mattress, the patient position detection system having at least first, second, and third alarm modes of operation, the patient position detection system being configured to provide for selection of one of the first, second, and third modes as a selected mode, the first mode of operation resulting in an alarm being activated in the event the first mode is the selected mode and the patient moves by a first amount, the second mode of operation resulting in the alarm being activated in the event the second mode is the selected mode and the patient moves by a second amount greater than the first amount, and the third mode of operation resulting in the alarm hem activated in the event the third mode is the selected mode and the patient moves a third amount greater than the second amount.

20. An apparatus for supporting a patient, the apparatus comprising:
-
a frame, a mattress supported by the frame, and a patient position detection system including an alarm and the patient position detector having first, second, and third modes of operation, the first, second, and third modes being selectable to permit adjustment of a sensitivity of the patient position detection system, in the event the first mode is selected, the alarm is activated in response to the patient moving a first distance, in the event the second mode is selected, the alarm is activated in response to the patient moving a second distance greater than the first distance, and in the event the third mode is selected, the alarm is activated in response to the patient moving a third distance greater than the second distance. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A patient support comprising:
-
a frame, a mattress supported by the frame, and a patient position detection system including a controller, an alarm, and a plurality of sensors, the controller being configured to receive data from the plurality of sensors indicative of the position of the patient relative to the mattress, the patient position detection system having a first mode of operation in which the controller activates the alarm to indicate that the patient is in a first position relative to the mattress, the patient position detection system having a second mode of operation in which the controller activates the alarm to indicate that the patient is in a second position relative to the mattress, the patient position detection system having a third mode of operation in which the controller activates the alarm to indicate that the patient is in a third position relative to the mattress, the data received by the controller from the plurality of sensors also being used by the controller to determine a weight of the patient resting on the mattress. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42)

43. A patient support comprising:
-
a frame, a deck positioned above the frame, a mattress positioned above the deck, and a patient position detection system including a controller, an alarm, and a plurality of sensors, the controller being configured to receive data from the plurality of sensors indicative of the position of the patient relative to the mattress, the patient position detection system having a first mode of operation in which the controller activates the alarm to indicate that the patient has moved a first distance from a location on the mattress, the patient position detection system having a second mode of operation in which the controller activates the alarm to indicate that the patient has moved a second distance from the location on the mattress, the patient position detection system having a third mode of operation in which the controller activates the alarm to indicate the patient has moved a third distance from the location on the mattress, the second distance being greater than the first distance, the third distance being greater than the second distance, the patient position detection system being configured to permit selection of the mode of operation to permit adjustment of a sensitivity of the system before the alarm is activated, the plurality of sensors including a plurality of load cells supporting the weight of the deck and providing data to the controller to determine the position of the patient and a weight of the patient resting on the mattress. - View Dependent Claims (44, 45)
