The Anesthetic Conserving Device Compared with Conventional Circle System Used Under Different Flow Conditions for Inhaled Anesthesia

Abstract
The Anesthetic Conserving Device (ACD) is a high-flow anesthesia system closed to volatile anesthetics only. We compared the ACD with a circle system under different fresh gas flow (FGF) conditions. Eighty-one patients undergoing major surgery were randomly allocated to receive sevoflurane from a ci
