Abstract

Two different forms of plethysmograph are commonly used to estimate limb blood flow noninvasively in humans: 1) the 'Whitney' mercuryin-silastic strain gauge, and 2) the 'Dohn' air-filled, double-walled, latex cuff. We tested the hypothesis that both techniques provide equal estimates of both absolute and relative blood flow. Bilateral calf blood flows were measured at rest and during reactive hyperemia (immediately after 10 min bilateral femoral occlusion) in 8 subjects (ages 21-40) in two sessions on the same day. Whitney and Dohn cuffs were (Figure Presented) placed on opposite legs for one session, and were g . reversed for the second session. Simultaneously
