A method for calibrating a stroemungssensors in a respiratory system

摘要

a method for calibration of a flow sensor in a respiratory system and in the respiratory system and results to influence the atemgasstromes is with respect to the influence of gasartzusammensetzung of atemgases are improved.to resolve the task provided that, for calibration of the actuators (4)11) to a closed respiratory system with 1 atemgasstrom be switched and the drive unit (13) with a pre-set time - volume relationship in the respiratory system (1) on the breaththe flow sensor (9) supports and by comparison of the time - volume relationship with the measurement signal of the flow sensor (9), a kalibrierwert for the flow sensor (9) is formed.
