Rationale 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 کاملVenous 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 کاملReproducibility of blood flow and post-occlusive reactive hyperaemia as measured by venous occlusion plethysmography.
Venous occlusion plethysmography is commonly used as a tool to assess BF (blood flow) and VR (vascular resistance) at baseline and during PORH (post-occlusive reactive hyperaemia). However, little is known about the reproducibility of this method. The purpose of the present study was to investigate short- (hours) and medium (week)-term reproducibility of forearm, calf and thigh BF and VR at bas...
متن کاملCerebral venous outflow resistance and interpretation of cervical plethysmography data with respect to the diagnosis of chronic cerebrospinal venous insufficiency.
OBJECTIVE While chronic cerebrospinal venous insufficiency (CCSVI) can be characterized using cervical plethysmography, much remains unknown about the haemodynamics associated with this procedure. The aim of the study was therefore to gain a deeper understanding of the observed haemodynamics. METHOD Forty healthy controls and 44 CCSVI patients underwent cervical plethysmography, which involve...
