Respiration device control method adjusts revs of rotary feed device during next inhalation phase dependent on detected position of bypass valve

摘要

The control method uses a control unit (6) coupled to the rotary feed device (1) supplying respiration gas to the inlet line (2) if the respiration device during the inhalation phase and to a bypass valve (5) inserted in a bypass line (4) between the inlet line and an outlet line (3). The feed device is operated a given rotation rate and the closure of the bypass valve during the inhalation phase is checked with the rotation rate of the feed device increased at the next inhalation phase when the bypass valve is closed and reduced at the next inhalation phase when the bypass valve is opened.
