[Modification of arterial blood flow using venous occlusion plethysmography]

Arterial blood flow volume was registered simultaneously by pulsed Doppler and venous occlusion plethysmography in 14 limbs of healthy subjects aged 25 to 36 years. The results were as follows: from the beginning of venous occlusion and during venous filling phase, arterial flow diminishes to 73% of its initial value. This diminution is due to a progressive decrease in arterial systolic flow as well as an increase in diastolic arterial reflux. The results reflect the increase in peripheral resistance as well as the elasticity of the arteries, which, during the diastole, return upstream a part of the arterial systolic flow.
