Disclosed is an autoCPAP respirator which comprises a control unit, a respiration blower and a pressure sensor. The control unit comprises a controller for generating a first control signal, which induces the speed of the blower to generate a pressurized breathing gas flow, a controller for generating a periodically variable control signal, which activates the blower such that the speed of the blower varies in an oscillating manner at a frequency in the range of 1-20 Hz, and a sensor device, which ascertains one or more of instantaneous speed, instantaneous electrical current and instantaneous electrical power of the blower to determine the breathing gas flow and/or breathing gas volume generated by the blower while using characteristic data of the blower stored in a memory.
An autoCPAP respirator, wherein the respirator comprises a control unit, a respiration blower, and a pressure sensor, the control unit comprising a first controller for generating a first control signal, which induces a speed of the blower to generate a pressurized breathing gas flow, a second controller for continuously generating a periodically variable control signal, which activates the blower such that the speed of the blower varies in an oscillating manner at a frequency in a range of 1-20 Hz, and a sensor device, which ascertains at least one of an instantaneous speed of the blower, an instantaneous electrical current of the blower, and an instantaneous electrical power of the blower, and wherein characteristic data of the blower stored in a memory, pressure values provided by the pressure sensor, and at least one of the instantaneous speed of the blower, the instantaneous electrical current of the blower, and the instantaneous electrical power of the blower are used to determine a breathing gas flow and/or breathing gas volume generated by the blower.
