Leg vascular conductance and peripheral pressure measurements during 2 min of passive limb movement in the supine and upright positions. Values are means ± SE for leg vascular conductance, mean arterial pressure, mean venous pressure, and perfusion pressure. Invasive measures of pressure were determined in 6 subjects. One minute of baseline data were collected before passive movement. The transition from baseline to passive movement occurred at time 0 on the x-axis.
