Errors in four-electrode impedance plethysmography

Medical and Biological Engineering and Computing, 1983
The errors in electrical impedance plethysmography are not well known. In the paper errors due to inadequate instrumentation, improper electrode application, and physiological changes have been analysed. Minimum electrical requirements for a general purpose four-electrode instrument are: (a) input impedance of voltage-sensing circuit+4 kΩ; (b) output ...

Impedance plethysmography

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 ...

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 ...
