The finger volume pulse and assessment of arterial properties.
Introduction The non-invasive assessment of cardiovascular function by means of the peripheral arterial pulse has gained substantial interest in recent years due to the integration of sensor technology and the ubiquitous application of microprocessors. In its most basic use, the peripheral pulse provides a signal that establishes the presence of a beating heart and quantifies the cardiac rhythm...
متن کاملVenous flow velocity, venous volume and arterial blood flow.
The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...

متن کاملAtrial natriuretic peptide regulates regional vascular volume and venous tone in humans.
OBJECTIVE To date, the contribution of basal atrial natriuretic peptide (ANP) levels to resting vascular function in humans is unknown. In the present study we sought to investigate the role of ANP in regulating regional vascular volume and venous tone in healthy subjects. METHODS AND RESULTS We used radionuclide plethysmography to examine the effects of ANP and the ANP-receptor antagonist A7...
متن کاملThe relationship between pulse volume and blood flow in the finger.
Accurate measurement of digital blood flow by plethysmography requires considerable attention to technical detail. Determination of digital pulse volume, on the other hand, is less difficult, and there are many sensing and recording devices available for this.1-5 In order to use pulse volume measurement as a routine laboratory procedure in the differential diagnosis of digital ischemia, however...
