Control of hospital bed chair egress configuration based on patient physiology
First Claim
1. A patient support apparatus comprisinga frame including a patient support deck, the patient 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,a lift system operable to support the patient support deck relative to an underlying floor at different heights,a control system to command operation of the lift system, the control system receiving data indicative of a height of the patient supported on the patient support deck, the control system determining an elevation at which the lift system is to support the patient support deck when the patient support deck is in the chair egress position based on the height of the patient, anda mattress supported on the patient support deck, the mattress having at least one inflatable bladder in a region of the mattress that supports the patient'"'"'s buttocks when the patient support deck is in the chair egress position supporting the patient in the sitting position, the control system including a pneumatic control system portion operable to inflate and deflate the at least one inflatable bladder, and the control system determining whether to deflate the at least one inflatable bladder when the patient support deck is in the chair egress position based on a weight of the patient.

Abstract
A patient support apparatus includes a frame having a patient support deck that is 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. Depending upon a height of the patient, a lift system is operated to support the patient support deck relative to an underlying floor at different heights when the patient support deck is moved to the chair egress position. Depending upon a weight of the patient, at least one bladder of a mattress is either deflated or further inflated when the patient support deck is moved to the chair egress position and the patient is in the process of egressing from the patient support apparatus.

17. A patient support apparatus comprising
a frame including a patient support deck, the patient 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, a mattress supported on the patient support deck, the mattress having at least one inflatable bladder in a region of the mattress that supports the patient'"'"'s buttocks when the patient support deck is in the chair egress position supporting the patient in the sitting position, and a control system operable to control the inflation and deflation of the at least one inflatable bladder, the control system receiving data indicative of a weight of the patient supported on the patient support deck, the control system operating to further inflate the at least one inflatable bladder when the patient support deck is in the chair egress position and the weight of the patient is above a threshold weight, and the control system operating to deflate the at least one inflatable bladder when the patient support deck is in the chair egress position and the weight of the patient is below the threshold weight.
