Abstract
The present invention is a method and system for adaptively detecting a patient trigger threshold. The system and method uses fuzzy-logic control algorithm to detect an appropriate trigger threshold by monitoring the number of patient triggers within a predetermined time frame. The system and method also detects an appropriated trigger threshold by monitoring the complete absence of false triggers over a predetermined time frame, increases in average flow, increases in pressure differential, and pressure drop, in order to lower the trigger threshold. The method and system of the present invention is selectable to the user, and adaptively changes the inspiratory trigger threshold.
