Responses to graded lower body negative pressure after space flightLower body negative pressure tests (0 to -60 mm Hg) were administered 2-3 times preflight and 4 times postflight (L0 to L7), to evaluate the effect of space flight on orthostatic responses. This paper presents preliminary findings from the first 4 crew members who have completed this protocol. Overall the results suggest a greater orthostatic strain lasting approximately two days postflight, that may have been due to enhanced pooling of blood in body regions other than the calf.
