The present invention relates to a device and a method for the decomposition of nitrous oxide in a gas stream, in particular for the decomposition of nitrous oxide in the expiration air flow of a patient, wherein the gas stream is passed through a nitrous oxide decomposition reactor containing a nitrous oxide decomposition catalyst, preferably a noble metal catalyst, and the temperature is controlled in said nitrous oxide decomposition reactor.
