Technical conception for an anesthesia system with electronic metering of gases and vapors.

The technical conception for an anesthesia system will be presented, which is designed to measure and to meter anesthetic gases and anesthetic vapor under computer control. By these means the oxygen supply and anesthetic vapor supply to the patient can be automated, which should allow to improve the patient's safety during anesthesia. In order to meet these objectives novel systems for measurement and metering of gases and anesthetic vapors have to be developed. Prototypes of these components will be described and a first design proposal for the anesthesia system will be presented.
