First Claim
1. A method for performing impedance measurements on a subject, the method including, in a processing system:
- a) causing at least one electrical signal to be applied to the subject via first leads operatively connected to first electrodes provided on the subject;
b) determining a first indication indicative of at least one first electrical signal measured via second leads operatively disconnected from second electrodes positioned on the subject while the at least one electrical signal is applied to the subject via first leads;
c) determining a second indication indicative of at least one second electrical signal measured via second leads operatively connected to second electrodes positioned on the subject while the at least one electrical signal is applied to the subject via first leads; and
,d) determining from the indications and the at least one applied signal, at least one instantaneous impedance value.

Abstract
A method for performing impedance measurements on a subject. The method includes, in a processing system, causing at least one electrical signal to be applied to the subject via first leads operatively connected to first electrodes provided on the subject, determining a first indication indicative of at least one first electrical signal measured via second leads operatively disconnected from second electrodes positioned on the subject, determining a second indication indicative of at least one second electrical signal measured via second leads operatively connected to second electrodes positioned on the subject, and determining from the indications and the at least one applied signal, at least one instantaneous impedance value.
