METHOD FOR DETECTING THE PORTION OF BRONCHOSPASM IN BRONCHIAL OBSTRUCTION Russian patent published in 2002 - IPC

FIELD: medicine, functional diagnostics. SUBSTANCE: one should detect the forced expiratory volume per 1 sec (FEV₁) before and after the intake of broncholytic preparation. Based upon the data obtained one should determine the gain of FEV₁ after the intake of broncholytic preparation and the difference of FEV₁ deviation against the lower standard limit before the intake of broncholytic preparation. The portion of bronchospasm in bronchial obstruction is determined by the percentage of FEV₁ gain after the intake of broncholytic preparation and the difference for FEV₁ and VC deviations against the lower standard limit. EFFECT: higher accuracy of diagnostics. 1 ex
