Claim 13:
14. The anesthesia machine according to claim 13, wherein to use the exhaled gas anesthetic concentration and the concentration of carbon dioxide in the exhaled gas to calculate the concentration of anesthetic in the gas reflowing into the inspiratory branch, in the exhaled gas, to obtain the re-inhaled gas anesthetic concentration, the processor is further configured to:
use the exhaled gas anesthetic concentration, the concentration of carbon dioxide in the exhaled gas, and a calculation model for the re-inhaled gas anesthetic concentration to calculate the concentration of anesthetic in the gas reflowing into the inspiratory branch, in the exhaled gas, to obtain the re-inhaled gas anesthetic concentration,
wherein the calculation model for the re-inhaled gas anesthetic concentration is a model created based on a process of changes in a first anesthetic concentration caused by a carbon dioxide absorption canister, the first anesthetic concentration being in a gas flowing through the carbon dioxide absorption canister.
