Abstract
A device, for dispensing an anesthetic into a gas stream, has a gas inlet, via which gas to be enriched with anesthetic and coming from a gas source flows in and with a gas outlet, via which gas enriched with anesthetic flows out to a patient port. A heating element, for heating the gas stream, is arranged upstream of an evaporation chamber, for dispensing an anesthetic into the gas stream, between the gas inlet and the gas outlet. The heating element is actuated by a control unit such that heat is fed to the gas to be enriched with anesthetic for evaporation of the anesthetic located in the evaporation chamber as a function of at least one status parameter of the gas to be enriched with the anesthetic and/or of the gas at least partially enriched with the anesthetic.
