BLOOD VOLUME CHANGES IN ALTITUDE EXPOSED RATS RETURNED TO AMBIENT PRESSURE

Total blood volume, plasma volume and red blood cell volume were measured in altitude acclimated rats (380 mm Hg) which were returned to ambient pressure for one and two week periods of deacclimation. The plasma volume was rapidly restored to and never exceeded control levels when rats were returned...

Description
Summary:Total blood volume, plasma volume and red blood cell volume were measured in altitude acclimated rats (380 mm Hg) which were returned to ambient pressure for one and two week periods of deacclimation. The plasma volume was rapidly restored to and never exceeded control levels when rats were returned to ambient pressure. The total red blood cell volume was found to decline at a faster rate in deacclimating animals than could be expected from normal cell destruction alone. The total blood volume reduction during deacclimation paralleled that of the total red cell volume.
