Classification: CPC A  G | IPC A  G

Claim 19:
20. The anesthesia machine according to claim 13, wherein to use the fresh gas flow rate, the inhaled gas flow rate, the inhaled gas anesthetic concentration, and the re-inhaled gas anesthetic concentration to calculate the concentration of output anesthetic of the anesthetic output device to obtain the anesthetic output concentration, the processor is further configured to:
use the fresh gas flow rate, the inhaled gas flow rate, the inhaled gas anesthetic concentration, the re-inhaled gas anesthetic concentration, and a first output concentration calculation model to calculate the concentration of output anesthetic of the anesthetic output device to obtain the anesthetic output concentration, wherein the first output concentration calculation model is a model created based on a premise that a process of changes in the inhaled gas anesthetic concentration in the inspiratory branch is ignored; or
use the fresh gas flow rate, the inhaled gas flow rate, the inhaled gas anesthetic concentration, the re-inhaled gas anesthetic concentration, a predetermined change rate for the inhaled gas anesthetic concentration, and a second output concentration calculation model to calculate the concentration of output anesthetic of the anesthetic output device to obtain the anesthetic output concentration, wherein the second output concentration calculation model is a model created based on a premise that a process of changes in the inhaled gas anesthetic concentration in the inspiratory branch is considered.
