Abstract/OtherAbstract:
The volume capacity of the venous system in the calves of 70 normal subjects was determined by passive and active changes in posture, using mercury-in-rubber strain gauges. The mean volume capacity was 1.26% (SD 0.39%) at a venous pressure of 0 kPa (o mm Hg) and 2.05% (SD 0.70%) at 1.60 kPa (12 mm Hg). With this method the blood flow in the calves at rest was measured without venous occlusion: 2.84 ml-100 ml-1/min (SD 1.20). During interpolated venous occlusion the mean blood flow was 2.67 ml-100 ml-1/min (SD 1.21). The pressure-volume relation over the pressure range 0 to 9.31 kPa (0 to 70 mm Hg) was determined in seven normal subjects.
