ABSTRACTFour plethysmographic techniques‐rheoplethysmography, electrical impedance plethysmography, girth plethysmography, and photoplethysmography–are described and their theoretic bases discussed. Advantages and limitations are noted, and particular emphasis is given to the optical methods and the use of glass fiber light guides in the construction ...

Equine Veterinary Journal, 1990
Summary The technique of impedance plethysmography is described and its application to observation of lung volume changes in the horse at exercise is discussed. The results from horse at rest show that there is a close relationship between rate of lung volume change (flow rate) and the associated impedance changes during both ...

Comparison of electrical field plethysmography with electrical impedance plethysmography
Annals of Biomedical Engineering, 1982As a means for assessing cardiac function, electrical field plethysmography (EFP) has been shown to have some features quite different from electrical impedance plethysmography (EIP). Here the two techniques are compared by using the two systems simultaneously on a subject and also with independent use in different electrode configurations. The results

Venous occlusive RN plethysmography: Comparison with electrical admittance plethysmography
Journal of Biomedical Engineering, 1984A venous occlusion plethysmography using radionuclide (RN) was introduced for the measurement of the limb blood flow. This technique, called RN plethysmography, can be carried out in a subject who has been previously administered RN intravenously for the routine angiographic examination.

Varitest plethysmography is a non-invasive diagnostic method of venous insufficiency based on the study of the emptying of leg veins by flexion movements and their subsequent filling. The Varitest records the curves and measurements of these two stages. The physiological bases of the test and its technique are presented.
