[Effects of weightlessness on baroreflex function].

Xian-yun Shen

Abstract

The declination of baroreceptor reflex function is one of the important factor causing orthostatic intolerance after space flight. The change of baroreceptor reflex function during weightlessness and simulated weightlessness is introduced, and the influence of elevatory upper body blood pressure and electrolyte changes caused by weightlessness on baroreflex function are analyzed.
