ELECTRIC FIELD PLETHYSMOGRAPHY FOR MONITORING OF CARDIAC AND RESPIRATORY ACTIVITY

H. Pfützner, K. Futschik

Abstract

A project is reviewed which applies Electric Field Plethysmography to both respiratory and cardiac components in an equal way. Electrode positioning and signal processing are optimized in order to produce a sum-signal which finally is separated into a respiratory and a cardiac signal by means of adaptive filtering, Neural Networks, weighted subtraction or Fourier analysis, respectively. For the first time, the test system offers a simple tool for a precise determination of the exact synchronism between respiratory and cardiac activity.
