EXPERIMENT INFORMATION

Blood Pressure Monitoring During Reentry (DSO 441)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Postflight orthostatic hypotension has been noted since the Mercury flights and can be expected after exposures to weightlessness. Orthostatic hypotension arises from fluid shifts, fluid loss, decreased peak physical loads, and from neurological adaptation. Due to concerns related to hypotension during Space Shuttle reentry, crewmembers were provided with antigravity suits (AGSs).

Concerns were expressed over orthostatic problems directly affecting the astronauts during and immediately following reentry.
