  • Patent number: 6155256
    Abstract: In a fresh gas system and a method for vaporizing a liquid anaesthetic in an anaesthetic machine, a gas preparation unit prepares a flow of fresh gas having a gas mixture from at least two sources of gas, the gas mixture is passed through a vaporizer where it picks up a quantity of anaesthetic related to the viscosity of the gas mixture. A control device controls the gas preparation unit. An arrangement is connected upstream from the vaporizer and is connected to the control device, for determining the composition of the gas mixture. The control device compensates the fresh gas system for the gas mixture's composition so that a specific amount of anaesthetic is always picked up by the gas mixture, regardless of the mixture's composition.
