SYSTEM AND METHOD OF IDENTIFYING RESPIRATORY INSUFFICIENCY OF SUBJECT'S RESPIRATION

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to systems and methods of identifying respiratory insufficiency. System contains processors, obtaining information related to subject's respiration, and executive modules. Modules include parametric module, key parameter module, and classification module. Parametric module determines parameters of subject's respiration on the basis of information obtained by processor, with parameters being determined for each preliminary inhalation-exhalation, and said preliminary inhalation-exhalation relates to separate inhalations-exhalations, and not to quality of inhalations-exhalations but only to the level of analysis in respiration identification. Module of key parameter determines values for key parameter of subject's respiration for each preliminary inhalation-exhalation from parameters, determined by parametric module, with key parameter representing parameter, which cannot be directly obtained from information, obtained by processor. Module of key parameter includes artificial neuron network, which models ratio between preliminarily determined set of respiration parameters and key parameter in response to inputs of respiration parameters of specified preliminary inhalation-exhalation, as well as determines value for key parameter for said specified preliminary inhalation-exhalation. Module of classification determines subject's respiratory insufficiency by comparison if determined value of key parameter for specified preliminary inhalation-exhalation with preliminarily determined threshold, classification, in response to comparison of separate preliminary inhalations-exhalations as real, productive, inhalations-exhalations or artifact, insufficient, inhalations-exhalations, respectively, and in response to classification of separate preliminary inhalations-exhalations. Parameters, determined by parametric module, include values, determined by aggregation of preliminarily determined sets of selections of CO₂ levels during specified preliminary inhalation-exhalation, with first parameter being determined from first set, which contains first quantity of selections of CO₂ levels during said preliminary inhalation-exhalation, other parameter being determined from the following set, which contains the following quantity of selections of CO₂ levels during the same specified preliminary inhalation-exhalation, and in response to said specified preliminary inhalation-exhalation, which is short inhalation-exhalation, not providing sufficient number of elements of selections for providing data, from which each of parameter values can be determined. Parametric module automatically prescribes preliminarily determined values to those elements of selections, which are not provided because of short inhalation-exhalation, and determines respective parameter with application of said prescribed values. Method includes stages of system work in order to identify respiratory insufficiency.;EFFECT: application of invention ensures improved determination of respiration parameters due to taking into account short inhalation-exhalation.;13 cl, 6 dwg
