MACHINE D'ANESTHÉSIE, PROCÉDÉ, SYSTÈME ET DISPOSITIF DE SURVEILLANCE DE CONCENTRATION DE SORTIE D'ANESTHÉSIQUE ET SUPPORT DE STOCKAGE

摘要

An anesthesia machine, an anesthetic output concentration monitoring method, system, and device, and a storage medium. The method includes: respectively monitoring a flow of a fresh gas flowing into a breathing circuit and a flow of an inhaled gas of an anesthetized object (S11); when the inhaled gas flow is greater than a fresh gas flow, respectively monitoring a concentration of anesthetic in the inhaled gas and an exhaled gas of the anesthetized object (S12); using the exhaled gas anesthetic concentration and a concentration of carbon dioxide in the exhaled gas to calculate a concentration of anesthetic in a gas, reflowing into an inspiratory branch, in the exhaled gas, thereby obtaining a re-inhaled gas anesthetic concentration; and using the fresh gas flow, the inhaled gas flow, the inhaled gas anesthetic concentration, and the re-inhaled gas anesthetic concentration to calculate a concentration of output anesthetic of an anesthetic output device, thereby obtaining an anesthetic output concentration.
