Simultaneous Electrical Bio-Impedance Plethysmography at Different Body Parts: Continuous and Non-Invasive Monitoring of Pulse Wave Velocity

IEEE Transactions on Biomedical Circuits and Systems, 2021
A simultaneous and time-synchronized electrical bio-impedance plethysmography (BPG) sensor system is implemented for long-term, continuous, and non-invasive measurement of arterial pulse wave velocity (PWV).

Meaning of Impedance Plethysmography [PDF]

open access: possibleNature, 1967
IMPEDANCE plethysmography is a method of measuring the resistive impedance of a limb segment. Nyboer1 pointed out that the resistive impedance variation ΔR during the heart cycle is proportional to the blood volume ΔV transiently stored in the segment where ρ is the blood ...

Diagnostic efficacy of impedance plethysmography for clinically suspected deep-vein thrombosis. A randomized trial.

Annals of Internal Medicine, 2020
Impedance plethysmography is an accurate noninvasive method to test for proximal vein thrombosis, but it is insensitive to calf-vein thrombi. We randomly assigned patients on referral with clinically suspected deep-vein thrombosis and normal impedance ...

Impedance plethysmography

Equine Veterinary Journal, 1990
SummaryThe 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 inspiration and expiration.

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, 1992
The 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.

Development of multielectrode impedance plethysmography

Medical & Biological Engineering & Computing, 1986
The feasibility of simultaneous independent measurements of impedance variations in the right and left apex and base of the lungs using the technique of multielectrode impedance plethysmography (MIPG) was investigated. To obtain independent impedance measurements in each region, high impedance sensitivity areas must be localised by weighting the ...

Comparison of electrical field plethysmography with electrical impedance plethysmography

Annals of Biomedical Engineering, 1982
As 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

Differential impedance plethysmography for measuring thoracic impedances

Medical & Biological Engineering & Computing, 1982
A critical evaluation of the measurement of the transthoracic basic impedance Zo according to Kubicek's method revealed inhomogeneous electrical field-distributions in the region of the neck and the shoulders and in the region of the mammae in female subjects. These inhornogeneties were found to introduce uncontrollable errors, like position dependency

The Clinical Implications of Bilaterally Abnormal Impedance Plethysmography [PDF]

open access: possibleArchives of Internal Medicine, 1987
Although impedance plethysmography (IPG) is a test of recognized value in the diagnosis of acute proximal deep venous thrombosis (DVT), its meaning in patients with bilaterally abnormal IPGs is unclear. Consequently, we sought to determine the clinical significance of the bilaterally abnormal IPG in hospitalized patients.

Printed Textile-Based Dry Electrodes for Impedance Plethysmography Measurements

2024 IEEE International Flexible Electronics Technology Conference (IFETC)
In this work, we report on the design, fabrication, and characterization of dry electrodes for the measurement of pulse plethysmography signals from distal arteries via electrical impedance.
