In the article chronic lung failure method of diagnostics in chronic obstructive pulmonary disease (COPD) patients based on computer pulse oximetry during stress testing (6-walking test and bicycle ergometer test) is given. The sensitivity and the specificity of method of diagnostics with ROC-analisis is assessed. As it's identified, bicycle ergometer test use allows to increase the informativeness of lung failure degree diagnostics due to identification of COPD persons without lung failure. Different degrees of lung failure are identified in 70% COPD patients using developed method of lung failure degree diagnostics. Sever degree of lung failure is revealed in 56% COPD patients. Lung failure degree that can decrease domestic stress testing tolerance and can get worse the quality of life is revealed in 56% COPD patients. The moderate straight relationship between lung failure degrees and severity lung failure classes and COPD exacerbation risk groups is detected.
