Abstract
A method and apparatus for evaluating the connection between the patient monitor and the patient. The apparatus is a compliance monitoring circuit that generates a constant current output to the isolation transformer of a patient monitoring device. Changes in the impedance of the patient connection cause changes in the output voltage of the constant current generator. This voltage can be measured and compared against a reference to generate a visible or audible compliance alarm.
