Patient support apparatus with cpr features

A patient support apparatus comprising:

• an inflatable cushion formed from a plurality of inflatable bladders;
• a pneumatic system for controlling the pressure in the plurality of inflatable bladders, the pneumatic system including a valve manifold in fluid communication with the plurality of inflatable bladders, wherein, when opened, the valve manifold allows air to quickly exhaust from the plurality of inflatable bladders to allow the inflatable cushion to deflate quickly;
• and
• a control system configured to electrically couple to a first DC power supply and to electrically couple to and disconnect from an AC power supply and further to rely on the first DC power supply when disconnected from the AC power supply, the control system further including an electrical actuator to selectively open the valve manifold, the control system configured to electrically couple a second DC power supply wherein the control system selectively powers the valve manifold actuator using the second DC power supply independent of the first DC power supply at least when the control system is disconnected from the AC power supply.

A patient support apparatus comprising:

• an articulatable deck with a pivotal back section;
• an inflatable cushion formed from a plurality of inflatable bladders;
• a deck actuator to raise or lower the back section of the deck;
• a control system for powering and controlling the deck actuator;
• a pneumatic system for inflating and/or deflating the inflatable bladders of the plurality of inflatable bladders, the pneumatic system including a valve manifold to allow air to exhaust from the inflatable bladders of the plurality of inflatable bladders to allow the patient to be supported on the deck, and the valve manifold including a valve manifold actuator selectively powered to open the valve manifold;
• and
• wherein the control system is configured to electrically couple to a first DC power supply and is configured to electrically couple to and disconnect from an AC power supply and to use the first DC power supply when disconnected from the AC power supply, and the control system being further configured to electrically couple to a second dedicated DC power supply to selectively power the valve manifold actuator independent of the first DC power supply for a predetermined time period.
