METHOD OF ESTIMATING METABOLIC AND CARDIORESPIRATORY ADAPTATION OF CARDIOSURGICAL PATIENTS Russian patent published in 2013 - IPC A61B5/83 A61B5/91 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to anesthesiology and intensive therapy and can be used in case of necessity to estimate degree of patient's metabolic and cardiorespiratory adaptation. For this purpose during operation and intensive therapy successive inhalation of gas mixture with 51% (FiO₂=0.51) and 21% (FiO₂= 0.21) content of oxygen is carried out. After that, consumption of oxygen and release of carbon dioxide at each stage are determined, and power of anaerobic threshold by FiO₂ in gas mixture, corresponding to the moment of anaerobic threshold achievement, is calculated. If power of anaerobic threshold is >0.14, degree of patient's metabolic and cardiorespiratory adaptation is considered to be low. If index value is <0.1, degree of patient's metabolic and cardiorespiratory adaptation is considered to be high. If index value is 0.1-0.14, degree of patient's metabolic and cardiorespiratory adaptation is considered to be medium.

EFFECT: method makes it possible to ensure reduction of probability of development of hypoxic complications in critical patients due to determination of degree of metabolic and cardiorespiratory adaptation during operation and intensive therapy, including mode of monitoring.
