Method and device for automatic determination of a ventilation volume during mechanical breathing taking leakages into consideration

摘要

The method involves determining artificial respiration volume as tidal volume under consideration of parasitic leakages and nominal leakages. Inspiratory and expiratory leakage volumes are determined by a volume measurement for inspiratory and expiratory tidal volume. A measurement of time for inspiratory and expiratory pressure curve is determined by omission of a breathing space and a relative relationship between an inspiratory and an expiratory leakage is calculated. An independent claim is included for a unit with a programmable microprocessor for automatic control of a respirator.
