Venous occlusion plethysmography is a useful tool to investigate the effect of a vaso-active medication on the venous circulation in man. However, room temperature can be very critical when small changes have to be detected. ⋯ It is likely that by lowering room temperature the response would be exaggerated. Taking these restrictions in mind, venous occlusion plethysmography can be a very valuable, non-invasive tool to study the effect of vaso-active treatment on the veins in men.
