Implantable Impedance Plethysmography [PDF]

open access: yesSensors, 2014
We demonstrate by theory, as well as by ex vivo and in vivo measurements that impedance plethysmography, applied extravascularly directly on large arteries, is a viable method for monitoring various cardiovascular parameters, such as blood pressure, with

A Cuffless Blood Pressure Measurement Based on the Impedance Plethysmography Technique [PDF]

open access: yesSensors, 2017
In the last decade, cuffless blood pressure measurement technology has been widely studied because it could be applied to a wearable apparatus. Electrocardiography (ECG), photo-plethysmography (PPG), and phonocardiography are always used to detect the ...

Toe digit pulsation measurement by impedance plethysmography in miniaturized devices: An early feasibility test [PDF]

open access: yesJournal of Electrical Bioimpedance
This early feasibility test explores impedance plethysmography (IPG) for detecting toe pulse waves using a setup suited for miniaturized devices. Conventional tests often miss micro-circulatory impairment, which is critical for wound healing and limb ...

Differential sensitivity of impedance plethysmography and photoplethysmography sensors to temperature-induced peripheral vasoconstriction [PDF]

open access: yesScientific Reports
Impedance plethysmography (IPG) and photoplethysmography (PPG) are non-invasive techniques for measuring blood volume changes. This study investigated the differential responses of IPG and PPG to temperature-mediated vasoconstriction induced by localized
