In order to reduce comsumption of inhalational anaesthetsics during high‐flow anaesthesia, a system open in regard to oxygen, nitrogen and nitrous oxide, but closed to inhalational anaesthetics, was developed. This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. The principle has been developed into the commercially available A nesthetic C onserving D evice ( ACD , AnaConDa ®). The ACD is a modified heat and moisture exchanger containing a bacterial and viral filter as well as a carbon filter. The ACD can be used for administering the inhalational agents isoflurane and sevoflurane as an alternative to low‐flow anaesthesia systems during surgery. It can also be used in intensive care units to administer sedation using isoflurane or sevoflurane to critically ill patients.
