Venous occlusion pressure plethysmography in the human upper limb.
Two techniques of venous occlusion pressure plethysmography were examined experimentally in the human upper limb. The first was the classical method, in which external pressure is applied to the limb solely by way of the plethysmograph. In the second, the entire upper limb including the plethysmograph and venous occlusion cuff was enclosed in a box within which the air pressure could be raised....
متن کاملRationale of venous occlusion plethysmography.
The experimental evidence reported here supports the validity of venous occlusion plethysmog-raphy. 1 modified the technic of Brodie, 2 venous occlusion plethysmography has been widely employed to estimate blood flow in fingers, toes, and limbs. Several excellent comprehensive reviews of the technical pitfalls of the method are available. 3-4 The validity of the venous occlusion technic of plet...
متن کاملHuman forearm venous occlusion plethysmography: methodology, presentation and analysis.
Forearm venous occlusion plethysmography is widely used for the study of arterial function in vivo in humans. In their timely paper on the effect of the angiotensinconverting enzyme inhibitor lisinopril on endothelial function in hyperlipidaemic patients, Lee et al. [1] raised several points of methodology relating to the correct analysis and presentation of data. Blood flow was measured in bot...
متن کاملAssessment of the human splanchnic venous volume-pressure relation using radionuclide plethysmography. Effect of nitroglycerin.
BACKGROUND No method exists to assess human splanchnic venous function, the most important region in terms of vascular capacity. METHODS AND RESULTS We studied 25 stable patients without heart failure or hypertension to develop a method to assess the splanchnic venous volume-pressure (V-P) relation and to determine the effect of nitroglycerin (GTN). We used blood pool scintigraphy to assess c...
متن کاملMeasurement by venous occlusion plethysmography of blood flow through surgically created arteriovenous fistulae in the human forearm.
1. Plethysmographs containing the hand plus forearm were used to measure blood flow in patients with a srugically created arteriovenous fistula in one forearm. 2. Apparent flow rate was stable over a limited range of collecting pressures; the absolute value of these pressures varied from patient to patient. 3. After arterial occlusion, blood flow increased by a similar amount on the normal side...
