ABSTRACT:
An anaesthetic system, which can be switched between an open system and a rebreathing system, includes a breathing circuit, a setting unit and a switching unit. When the breathing circuit is connected as a rebreathing system and a change in anaesthetic concentration or a change of anaesthetic type is initiated via the setting unit, the switching unit automatically sets the breathing circuit as an open system for a predetermined period of time, at the end of which the breathing circuit is automatically reset as a rebreathing system.
