Automatic blood pressure measurement in hyperbaric chamber

摘要

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.
