Abstract (en)

[origin: FR2767466A1] Uses variation in turbine supply current supplying a respiratory mask to produce a respiratory image. The method administers a respiratory gas to a pressure level by a turbine driven by a motor and permanently measures the current taken by the turbine motor so as to deduce the current used. It processes the current used signal, and determines a nasal or buccal respiratory image from the processed current signal. The current processing includes stages of filtering, integration and/or amplification and a memory stage.
