Abstract:
1. A patient support apparatus comprising a frame, a mattress support deck coupled to the frame, the mattress support deck being movable between a horizontal position to support a patient in a lying position and a chair egress position to support the patient in a sitting position, at least one actuator coupled to the mattress support deck and operable to move the mattress support deck between the horizontal position and the chair egress position, and control circuitry coupled to the at least one actuator and operable to command operation of the at least one actuator, the control circuitry being operable to receive a chair lockout signal and, in response to receipt of the chair lockout signal, the control circuitry operating to prevent the at least one actuator from being operated to move the mattress support deck into the chair egress position, wherein the mattress support deck includes a head section and a foot section, the at least one actuator comprises a first actuator operable to move the head section and a second actuator operable to move the foot section, and receipt of the chair lockout signal by the control circuitry results in the control circuitry preventing simultaneous operation of the first and second actuators, wherein the first actuator and the second actuator are each operable individually even if the control circuitry has received the chair lockout signal unless the first and second actuators have been locked out individually.
