Abstract:
A method of determining the amount of skin contact between a biomedical electrode and skin of a patient, comprising the steps of:(a) measuring change of phase angle over change in time (.delta..THETA./.delta.t) of an energized biomedical electrode in contact with a patient's skin;wherein the measuring step uses the equation:.THETA..sub.Total =[.theta..sub.Lossy Dielectric *(Area.sub.Lossy Dielectroc /Area.sub.Total )]+[.THETA..sub.Bare Metal *(Area.sub.Bare Metal /Area.sub.Total)]; and(b) sounding an alarm when .delta..THETA./.delta.t exceeds a predetermined amount; .delta..THETA./.delta.t being indicative of the amount of skin contact between a biomedical electrode and the patient's skin.
