  • Process for the calibration of a flow sensor in a respiratory system
    Patent number: 5253640
    Abstract: 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.
