ABSTRACT:
A process and device to determine the image of the nasal and/or buccal respiratory flow of a user, in which a respiratory gas at at least one pressure level is administered by means of at least one blower driven by a motor. The current consumed by the blower motor is continuously measured and a consumed current signal is generated. The consumed current signal is processed and an image of the nasal and/or buccal respiratory flow of the user is determined from the processed current signal.
