System and method for monitoring anesthetic agent fill level

Abstract:

A system for monitoring anesthetic agents fill level in a vaporizer reservoir includes a camera configured to capture an image containing a sight glass on the vapor reservoir, just like, a processor, and an agent level module. The agent level module is executable to locate a sight glass portion within the image, an agent level edge within the sight glass portion, and minimum and maximum reference points within the image. A fill percentage is calculated based on a position of the agent level edge relative to the minimum and maximum reference points, and the remaining agent information is calculated based on the fill percentage and the known volume of the vaporizer reservoir.
