A significant fraction of astronauts experience postflight orthostatic intolerance (POI) during 10-min stand tests conducted on landing day. The average time that nonfinishers can stand is about 7 min. This phenomenon, including the delay in occurrence of presyncope, was studied with a five-compartment model of the cardiovascular system incorporating compartments for the heart/lungs, systemic arteries and cephalic, central, and caudal veins. The model included 28 independent parameters… CONTINUE READING
