Method and arrangement for the tiration of physiological measuring signals in conjunction with the observation of a patient in terms of sleep-related respiratory problems
First Claim
1. A method of generating an evaluation result which is specific in respect of the physiological state of a person, on the basis of measurement signals which are in a relationship with the respiration of the person, wherein evaluation features are generated from said measurement signals, using a plurality of evaluation systems, and at least one evaluation result is generated in the context of a result-generation step based thereon, by the evaluation features being subjected to interlinking consideration, and the measurement signals are detected in titration sequences which are different in respect of the respiratory gas pressure level applied to the patient and the generation of at least a part of the evaluation features or the evaluation result is effected having regard to the respective titration sequence pressure.

Abstract
The invention concerns a method and an arrangement for the titration of physiological measurement signals. In particular the invention concerns a method and an arrangement for detection and evaluation of a measurement signal indicative in respect of the respiratory gas flow of a sleeping person, in conjunction with the observation of sleep-related breathing disorders. The object of the invention is that of providing solutions which make it possible to detect physiological properties which are relevant in respect of respiration during a sleeping phase, in a manner which makes it possible to assess the physiological state of the person being investigated with a high level of reliability and correctly match any therapy boundary conditions that are required. In accordance with a first aspect of the present invention that object is attained by a method of providing an evaluation result indicative in respect of the physiological state on the basis of measurement signals which are related to the respiration of a person, wherein evaluation features are generated from said measurement signals using a plurality of evaluation systems, and in the framework of a result-generation step based thereon at least one evaluation result is generated, by the evaluation features being subjected to interlinking consideration, wherein the measurement signals are detected in titration sequences which are different in respect of the respiratory gas pressure level applied to the patient and the generation of at least a part of the evaluation features or the evaluation result is effected having regard to the respective titration sequence pressure.

63. Apparatus for generating an evaluation result which is specific in respect of the physiological state of a breathing person, on the basis of measurement signals which are related to the respiration of the person, comprising a measurement signal input device and a computing device for providing a plurality of evaluation systems, wherein the computing device is configured in such a way that it generates evaluation features from said measurement signals by the evaluation systems and said evaluation features are subjected in the context of a result-generation step based thereon to interlinking consideration and an output signal or an output data set which contains the evaluation result is generated on the basis of the interlinking consideration, and the measurement signals are detected in titration sequences which are different in respect of the respiratory gas pressure level applied to the patient and the generation of at least a part of the evaluation features or the evaluation result is effected having regard to the respective titration sequence pressure.
- 64. A method of patient-specific configuration of a CPAP-apparatus in which in the context of a titration period in respect of the physiological state of a person specific evaluation results are obtained on the basis of measurement signals which are in a relationship with the respiration of the person, wherein evaluation features are generated from said measurement signals, using a plurality of evaluation procedures, and said patient-specific setting of the CPAP-apparatus is effected in dependence on said evaluation features, and following the titration period operation of the CPAP-apparatus is effected under therapy conditions which are ascertained as suitable, wherein in the context of the titration mode control of the respiratory gas pressure is effected in accordance with a pressure regulating concept which under program control causes the setting of different respiration gas pressure levels in such a way that the measurement signals are detected in titration sequences which are different in respect of the respiratory gas pressure level applied to the patient, wherein the generation of at least a part of the evaluation features is effected having regard to the respective titration sequence pressure.
