Abstract
Blood pressure measurements are performed on subjects disposed in hyperbaric chambers. The measurements are made by an automatic blood pressure monitoring instrument having a differential pressure transducer component. The reference side of the pressure transducer is open to the pressure in the hyperbaric chamber. A rotary vane pump is used to inflate the cuff with the inflation fluid supply from within the hyperbaric chamber, and exhaust from deflating the cuff is vented back into the hyperbaric chamber.
