ABSTRACT:
A transducer for medical monitoring comprises a box (73) which contains a floating section, a non-floating section and a transformer or optical coupler for converting a floating signal into a non-floating signal. The box (73) provides a non-floating signal to an associated monitor. The common-mode rejection ratio is drastically improved, so that electrode gel between the reference electrode and the patient, and possibly even the reference electrode itself, may be omitted.
