Abstract (en)
[origin: WO2005068004A1] The invention relates to a respiration device for the treatment of sleep apnea, with which a measurement of the airway resistance ROS of the person is possible using a measurement of the alternating pressure in the breathing mask, in particular, during breathing therapy. Neither an additional valveless pump for generation of a reference flow nor an additional supply tube for supply of the reference flow into the face mask are used. According to the invention, a respiration device for the therapy of sleep apnea is provided, comprising a breathing mask (6), fitted to a breathing tube (5), an electric fan (1), driven at varying speed for generation of a speed-dependent therapeutic pressure, a controller, in particular, a computer (3), for control of the fan speed and a pressure sensor (10), for determination of a pressure in the breathing mask (6), said pressure sensor (10), providing an electrical pressure measuring signal (uM), characterised in that the controller is embodied for a periodical change in the speed of the fan (1) with a constant, preferably inaudible frequency and for analysis of the alternating voltage components in the electrical pressure measuring signal (uM) due to the pressure variations generated at the outlet of the fan (1) caused by the periodic changes in speed thereof and for controlling the therapy, in particular for setting the therapeutic pressure.
