  • Respiration system
    Patent number: 9802016
    Abstract: Respiration system for non-invasive positive-pressure respiration, with a pressure source providing respiratory gas, with a control and evaluation unit connected to sensors detecting a leakage volume, spontaneous respiration frequency, tidal volume and the inspiration time. The control and evaluation unit I) checks the leakage volume and reduces the inspiratory pressure assistance proceeding to ii) or triggers an alarm and returns to I), ii) checks the frequency and triggers an alarm and returns to I) or reduces or increases the inspiratory pressure and returns to I) or proceeds to step iii), iii) checks the volume and reduces or increases the inspiratory pressure and returns to I) or leaves the pressure assistance unchanged proceeding to step iv), iv) adjusts the time period of the pressure assistance, depending on the inspiration time, the time period being left unchanged if the inspiration time lies in the predefined inspiration time interval, and returns to I).
