A method for monitoring the impedance in a circuit coupling a radio frequency electrode to a radio frequency generator to control the power supplied by the generator to the electrode during a treatment procedure. In the method, the impedance in the circuit is monitored over a length of time. An expected impedance at the end of the treatment procedure is calculated from the monitored impedance and compared to a predetermined maximum impedance. The power supplied to the circuit is reduced if the expected impedance is greater than the predetermined maximum impedance. A computer-readable memory and apparatus utilizing the method are provided.
