Closed-loop control for anesthesia breathing systems.

Numerous medical applications of closed-loop control have been developed over the past 40 years. For the patient breathing system, appropriate sensors are available. Feedback controllers have been developed and tested. Gas and vapor delivery devices seem ready for use. With the sensors, controllers, and delivery devices developed and tested, it seems likely that closed-loop control will be an integral part of future anesthesia workstations. The convenience and improved stability and response time will be important advantages in future anesthesia delivery systems.

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.
