摘要： PROBLEM TO BE SOLVED: To alleviate closing of an upper airway during sleeping by supplying pressure that varies against the atmosphere into the upper airway of a patient and developing the dilation muscle of the airway. SOLUTION: A treating device 10 supplies air to a patient 12 alternately at relatively low and high pressures. The treating device 10 has a pressure bottle 16 and a gaseous stream producer 14. A gaseous stream from the gaseous stream producer 14 is supplied via a delivering tube 20 to a mask 22 mounted on the patient 12. The mask 22 has an exhausting aperture 24 for exhaustion of a breathing gas. A pressure controller 26 controls pressure of the gaseous stream within the delivering tube 26, that is, within the airway of the patient 12. A flow amount converter 28 is arranged in downflow of the pressure controller 26. An output signal 29 of the flow amount converter 28 is supplied to a flow amount signal adjusting circuit 30. The circuit produces a signal in proportion to a spontaneous flow amount of a breathing gas to the patient within the delivering tube 20. The spontaneous flow amount signal 32 from the signal adjusting circuit 30 is supplied to a determining circuit 34. An output of the determining circuit 34 controls a pressure controller 26 as a driving signal 42. A pressure value of the breathing gas corresponds to natural breathing of the patient 12.

摘要： The invention relates to a method of detecting changes in the respiratory state of a patient between inspiration and expiration. The method is of use in the control of obstructive sleep apnea using apparatus for administering a continuous positive airway pressure (CPAP) to the patient, and involves the continuous monitoring of the respiratory gas flow of the patient. From the monitoring, a respiratory gas flow characteristic is determined repeatedly at selected time intervals. Pairs of gas flow characteristics are determined at each selected time. One of each pair is the patient's actual respiratory gas flow rate at the selected time. The other is a prediction of the patient's gas flow rate at that selected time, obtained for example from the actual patient respiratory flow rate obtained at an earlier time. The characteristics of each pair are compared, and from the comparison changes in the patient's respiratory state between inspiration and expiration are identified.

摘要： A method of determining the leak component of gas flow in a system for delivery of breathing gas, such as for the treatment of obstructive sleep apnea through application of alternating high and low level positive airway pressure within the airway of the patient. The high and low airway pressure is coordinated with the spontaneous respiration of the patient.
