Zusammenfassung:	A supply arrangement (100) and a process supply a medical device (50, 90) with a supply gas mixture. The supply gas mixture includes a carrier gas and an anesthetic and is generated by an anesthetic dispenser (3). A carrier gas mixing unit (9) generates the carrier gas from at least two carrier gas components. A carrier gas switch having a regular outlet and a discharge outlet selectively directs carrier gas components to the carrier gas mixing unit or to a discharge line (35). A gas mixture switch (6), having a regular outlet (41) and a discharge outlet (42) selectively directs the supply gas mixture to the medical device or to the discharge line (35). An anesthetic concentration sensor (5.1, 5.2) measures a concentration of anesthetic in the generated gas mixture. A control unit (2) controls the gas mixture switch based on measured concentration within or outside a predefined range.
