SYSTEM AND METHOD FOR TRACKING ANESTHETIC AGENT IN A VAPORIZER RESERVIOR

Abstract:

A system for tracking anesthetic agent in a vaporizer reservoir can include a mass flow sensor configured to measure a flow rate entering or exiting a vaporizer chamber, a gas pressure sensor configured to measure a pressure of a mixed gas provided from the vaporizer chamber, and a processor to calculate a remaining agent time based on at least the gas flow rate, the pressure of the mixed gas, and an anesthetic concentration in the mixed gas. The processor can also provide the remaining agent time for display to a clinician.
