The procedure and the apparatus serve for the control of a respirator device which is used for the supply of breathable gas to a patient. At least one sensor for the capture of the time-wise evolution of at least one respirator-treatment parameter is provided. The sensor can be arranged in the area of an air delivery which encompasses a respirator device as well as a connecting installation. The sensor is connected to an analyzer which carries out a pattern recognition and which is connected to a control for the modification of at least one respirator-treatment parameter. In order to implement the pattern recognition, one captures&#x2014;at least at intervals&#x2014;the time-wise evolution of at least one of the respirator-treatment parameters.

Procedure for the control of a respirator device as well as apparatus for monitoring

A method of controlling a respirator for therapeutic treatment of sleep aa includes the step of continuously measuring a) a phase angle of a time difference between respiratory flow and respiratory pressure of a patient and b) a pressure amplitude of the patient. The individual respiratory resistance is determined based on the measured pressure amplitude by oscilloresistometry. The respiratory gas pressure is controlled based on the phase angle, the pressure amplitude, and the respiratory resistance. Significant changes of the phase angle are filtered from the signal of the phase angle. A control signal is produced based on the significant changes for controlling the respiratory gas pressure.

Method and device for controlling a respirator for therapeutic treatment

For controlling a respirator for treatment of sleep apnea, a patient's oscillatory pressure amplitude, which corresponds to a patient's breathing resistance is continuously measured, and the individual breathing resistance value (base value) of a patient's pressure amplitude is determined, by oscilloresistometry (oscillatory resistance measuring=ORM). If deviations from this base value occur, the patient is supplied with respiratory gas under pressure and the gas supply is terminated or minimized as soon as the base value is again reached or almost reached.
