Venous occlusion plethysmography with mercury-in-rubber strain gauges.
The Whitney plethysmograph consists of a mercury-in-rubber strain gauge together with a Wheatstone bridge. It can be used to measure, in a non-invasive way, the blood flow in extremities. A simple theoretical and practical study is lined out, showing that the apparatus is fully acceptable for clinical use. (Acta anaesth. belg., 1980, 31, 5-14).
