A respirator device for use in treating obstructive sleep apnea is described, with a pressure generator for generating an artificial atmosphere having a treatment pressure, with a pressure regulating device for controlling the pressure generator, and with a respiratory tube with a breathing mask for supplying the artificial atmosphere generated by the pressure generator to a patient, which is characterized in that it has a control mechanism for the continuous determination of a pressure loss occurring over an airway resistance in the airways of the patient, and for the essentially proportional adjustment of the pattern of treatment pressure to the pattern of the determined pressure loss. The use of a respiratory device of this type for the treatment of sleep apnea substantially decreases the strain on the respiratory musculature of the patient, makes the course of treatment more pleasant, and decreases potential secondary effects of the treatment.
A respiratory device for treating obstructive sleep apnea comprising a pressure generator for generating an artificial atmosphere at a treatment pressure, a pressure regulating device for controlling said pressure generator, a respiratory tube with a breathing mask for supplying the artificial atmosphere generated by the pressure generator to a patient, and a control mechanism for continuously determining a pressure loss that results from an airway resistance of the patient and for the essentially proportional adjustment of the treatment pressure pattern to the pattern of the determined pressure loss.
A method for controlling a respiratory device controlling a pressure generator for generating the treatment pressure by a control mechanism such that the treatment pressure of the artificial atmosphere is adjusted based upon a predetermined basic pressure, changing said treatment pressure by a portion of the actually determined pressure consumed at an airway resistance in the airway of the patient.
