Psychophysiology, 1965
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 ...

Thrombosis Research, 1985 Strain gauge plethysmography and impedance plethysmography are non-invasive diagnostic techniques for deep venous thrombosis. In 145 consecutive out-patients presented with suspected acute deep venous thrombosis we compared these two techniques ...

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 ...

Features of Pulse Plethysmography and a Comparison with Impedance Plethysmography
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992The features of current pulse plethysmography are given. The skin capacitance and resistance are depending upon pulse duration but not the internal resistance. The internal resistance changes depend of arteries volume changes. A comparison between pulsed plethysmography and sine-wave plethysmography is discussed.

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.
