Abstract: The feasibility of real-time monitoring of the inhalational anesthetic (sevoflurane) concentration in the respiratory circuit of an apparatus for inhalational anesthesia using mass spectrometry is considered. It is shown that the absolute anesthetic concentration can be monitored in real time if low-flow ventilation is provided during general anesthesia. The time dependences of the anesthetic concentration are taken at different stages of anesthesia in the inspiration-expiration regime.
