Central volume expansion may blunt carotid baroreflex sensitivity; hypothesis-generating for autonomic effects in volume-overload states.
Does lower body positive pressure-induced increase in central venous pressure diminish carotid baroreflex responsiveness?
Increases in central venous pressure and/or central blood volume diminish the sensitivity of the carotid baroreflex control of heart rate and mean arterial pressure.
