BACKGROUND This project was designed as an epidemiological aid-selecting tool for a small country health center with the general objective of screening out possible coronary patients. Peripheral artery function can be non-invasively evaluated by impedance plethysmography. Changes in these vessels appear as good predictors of future coronary behavior. Impedance plethysmography detects volume var...

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 pulse transit time (PTT) because the changed tendencies of the PTT and blood pressure have a negative relationship. In this study, the PPG signal...

— In the clinical set, the evaluation of endotheliumdependent vasodilator response of large vessels is carried out using ultrasound equipment for vascular flow determinations and during administration of vasoactive drugs. This work proposes to use a substantially cheaper technique and a sustained cuff arterial occlusion in order to cause vasodilation. Impedance plethysmography is used to detect...

UNLABELLED Impedance plethysmography is a method for determining changes in body tissue volumes, based on the measurement of electric impedance at the body surface. Because it is a non-invasive and cost-effective method to measure and analyze hemodynamics, it would bring to physiologists very important diagnostic information for the continuous care of critical patients with hemodynamic disorder...

Abstract Foot impedance plethysmography was implemented using two types of electrodes (dry and capacitive) sole force sensors. The latter are commonly used for assessing diabetic foot ulcers (DFU). For plethysmography, a tetrapolar configuration has been with three different plantar setups: four skin contact electrodes, capacitive Force Sensing Resistors (FSRs). In this work, FSRs have consider...

T HE INCREASE of pulse wave velocity with age is well established1-3 and reflects a loss of the elastic properties of the arterial wall.4 The age trends of pulse wave velocity vary for different arteries.2 8 In view of early localization of atherosclerotic changes in the abdominal aorta, we have compared age trends of the aortic pulse wave velocity, measured by impedance plethysmography in norm...
