Impedance Plethysmography - an overview | ScienceDirect Topics
Impedance plethysmography measures the change in blood volume in the calf from the impedance of a blood pressure cuff after rapid deflation. The measurements are determined by electrodes placed on the calf. When performed appropriately, it has high sensitivity (91%) and specificity (96%) for proximal vein thromboses.
Impedance Plethysmography - an overview | ScienceDirect Topics
Impedance plethysmography is a noninvasive test that uses electrical monitoring in the form of impedance changes to measure certain parameters, such as respiration rate, cardiac rate, and water content of the lungs (through the thorax impedance variations).
25. Impedance Plethysmography
Impedance plethysmography is a method of determining changing tissue volumes in the body, based on the measurement of electric impedance at the body surface. This chapter presents the bioelectric basis of impedance plethysmography with emphasis on impedance cardiography - that is, determination of cardiac stroke volume.
Impedance cardiography - Wikipedia
Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the ...

2005年9月1日 · Impedance plethysmography (IPG) is used to measure electrolyte fluid volume through changes in electrical conductivity. The instrument passes a weak (1 mA) alternating current through a limb and measures the electrical resistance to current flow.
Impedance plethysmography: A noninvasive means of …
1970年11月1日 · Impedance plethysmography, through recent technical advances, provides a clinically applicable means for detecting and quantifying acute or chronic changes in intrathoracic fluid by the associated alterations in conduction of a very small electrical current.
We propose impedance plethysmography as a well integrable alternative to PPG for the estimation of absolute respiratory flow and rate. Employing nested cross-validation and wrapper techniques in a model and feature selection framework, we analyzed different polynomial and multilayer perceptron regression models as well as feature sets.
