Prediction of bronchial permeability disturbance from breathing patterns

Abstract

Health subjects (n = 15), patients with bronchial asthma (n = 30), COPD (n = 16), and community-acquired pneumonia (n = 17) have been inspected in the mixed group (40 men, 38 women, 15-64 years old). The results of research of breathing patterns with interruption of air stream have been used to construct Raw, FEV1, FEV1% and FEV1/FVC% mathematical models. High diagnostic importance of FEV1% and FEV1/FVC% models in prediction of bronchial permeability disturbance has been shown.
