A true to life simulation of electrosurgery.

A laboratory simulation has been devised for use in developing and testing physiologic monitoring systems' performance in the presence of electrosurgical interference. This facilitated the development through iterative optimization of an EEG based parameter whose performance is improved during electrosurgery. The system was found to have an improvement of 94% in response to electrosurgery interference in the laboratory simulation. It was found to be improved 78% from all interference sources when tested clinically during actual surgery. This demonstrates the efficacy of the simulation.
