Calf venous compliance measured by venous occlusion plethysmography: methodological aspects

摘要

Calf venous compliance (C (calf)) is commonly evaluated with venous occlusion plethysmography (VOP) during a standard cuff deflation protocol. However, the technique relies on two not previously validated assumptions concerning thigh cuff pressure (P (cuff)) transmission and the impact of net fluid filtration (F (filt)) on C (calf). The aim was to validate VOP in the lower limb and to develop a model to correct for F (filt) during VOP.
