An anaesthetic system, which can be switched between an open system and a rebreathing system, is described. The anaesthetic system comprises a breathing circuit (2), a setting unit (18) and a switching unit (16, 20, 22, 30). When the breathing circuit (2) is connected as a rebreathing system and a change in anaesthetic concentration or anaesthetic is initiated on the setting unit (18), the switching unit (16, 20, 22, 30) automatically sets the breathing circuit (2) as an open system for a predetermined period of time, the rebreathing system being reset thereafter. <IMAGE> |
