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 pressure on the reference side of the pressure transducer is equal to the pressure in the hyperbaric chamber. The reference pressure is derived from a pressure source which equals the pressure in the hyperbaric chamber, but which pressure source does not contain the high purity oxygen gas in the hyperbaric chamber.
