How reproducible is bilateral forearm plethysmography?

Forearm plethysmography: does the right arm know what the left is doing?

We read with interest the recent Comment by ChinDusting et al. [1] entitled ‘Human forearm plethysmography: methodology, presentation and analysis ’ which addresses some important issues in the interpretation of studies using this technique. As the authors acknowledge, even when experimental conditions are carefully controlled, forearm blood flow (FBF) varies constantly in response to changes i...

Human 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...

Platelet Refractoriness and how it is formed

Abstract Background and Objectives Transfusion of platelet has become one of the main treatments for thrombocytopenic patients to reduce the severity and frequency of bleeding consequences. Failure to attain the desired level of platelets in a patient following platelet transfusion is defined as platelet refractoriness. The purpose of present paper is to review and study the mechanisms involve...

Comparison of two plethysmography systems in assessment of forearm blood flow.

Venous occlusion plethysmography is widely used to assess forearm blood flow (FBF). We compared the established Hokanson system (HEC4) with a newly developed Filtrass 2001 system (F2001). The HEC4 uses mercury-in-Silastic strain gauges, whereas F2001 detects volume changes with a nonmercury linear displacement device. The aim of this study was to evaluate the new F2001 against the HEC4 in terms...
