EXPERIMENT INFORMATION

Noninvasive Estimation of Central Venous Pressure During Space Flight (DSO 462)
Principal Investigator
Research Area:
Cardiovascular physiology
Renal, fluid and electrolyte physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Evidence suggests that cephalad fluid shifts during weightlessness stimulate arterial and cardiopulmonary baroreceptors, leading to cardiovascular readaptation syndrome. Central venous pressure (CVP) is one variable used to monitor fluid shifts. A noninvasive Doppler technique was used to document CVP during weightlessness.
