Adaptive REM Monitoring

Force 2 User’s Guide

Adaptive REM Monitoring

After the patient return electrode is applied and the initial impedance is 
between 5 ohms and 135 ohms, the “adaptive” REM system measures the 
contact impedance and uses it as a reference value.  If the patient-to-pad 
impedance increases 40% above this reference value or above 135 ohms, 
the REM alarm sounds and the monopolar output is disabled.  The 
adaptive REM system is designed to calibrate itself with respect to each 
patient.
