摘要： A process for calibrating a flow sensor in a respiratory system, with final control elements arranged in the respiratory system for influencing the respiration gas stream, is to be improved in terms of the influence of the qualitative gas composition of the respiration gas. To accomplish the task, the final control elements 4, 11 are switched, for calibration, over to a closed respiratory system with directed respiration gas stream. The drive unit 13 feeds the respiration gas present in the respiratory system through the flow sensor 9 according to a predetermined time-volume relationship. A calibration value for the flow sensor 9 is formed by comparison of the time-volume relationship with the measured signal of the flow sensor 9.

摘要： A metering device for a liquid anesthetic that is fed from a reservoir via a supply line into a heatable intermediate container maintained under pressure, from which gaseous anesthetic is fed via a metering valve into a fresh gas line. Accurate metering, which can be better monitored, is provided for low-boiling anesthetics. A supply unit 7 is mounted in the supply line 5, and liquid anesthetic is transported by the supply unit 7 into the intermediate container 6 until it is filled up to a predetermined filling level. A heating device 12 stabilizes the temperature of the liquid bath and ensures a sufficiently high vapor pressure of the gaseous anesthetic above the liquid phase. The anesthetic vapor is sent via the metering valve into the fresh gas line.
