We present an algorithm that permits automated acquisition, display, and disk storage of single or dual channel sensory evoked potential waveforms using a Pathfinder II evoked response monitor. Once initiated, data acquisition and storage continue at user-specified intervals without additional user input. A cascade screen display provides trend monitoring. The file for data storage is established and searched using standard Pathfinder commands. The algorithm is written in MECOL, the Pathfinder specific programming language. This programming code imposed a number of limitations that had to be overcome to create a versatile and user friendly algorithm. During clinical use in our operating rooms, the program has been found effective and easy to use by both veteran and novice Pathfinder operators. The "handsoff" trend monitoring permitted by this algorithm has reduced the labor-intensive aspect of sensory evoked potential monitoring.
