Principles of Measurement of Anaesthetic Agent Concentrations in Closed-Circuit Systems

Abstract

The measurement of concentrations of anaesthetic agent and nitrous oxide in the breathing circuit may be carried out at three sites in the system: measurement in the inspiratory limb allows at least control of the gas actually led to the patient, while measurement between Y-piece and patient or in the expiratory limb of the circuit will give important information on expiratory concentration values. Ideally, the end-expiratory value is measured.
