Hyperbaria may blunt resting sympathetic outflow without affecting hypovolemic responsiveness; leaves open mechanisms of atmospheric pressure effects on autonomic control.
Does a hyperbaric environment attenuate sympathetic nerve activity and its response to hypovolemic stress in men?
Hyperbaria attenuates baseline sympathetic nerve activity but does not alter its responsiveness to central hypovolemic stress.
Yamauchi et al. (2002) studied this question.
