概要

論文の詳細を見る
Volume of isoflow, closing volume, spirometory, maximal expiratory flow volume curve, respiratory resistance and arterial blood gases were obtained in 100 cases of obstructive pulmonary diseases (52 men and 48 women). The volume of isoflow was measured after 3 vital capacity inspiration, continuous resting breathing and 2 vital capacity inspiration of 80% helium and 20% oxygen continuously. The closing volume was measured by the resident method. In 22 cases, most of which were pulmonary emphysema, the closing volume was not obtained. There was a linear correlation relationship between the closing volume and volume of isoflow (r=0.62) and not any correlation relationships between _ΔV_<50> and FEV_<1.0>, Rr, V_<50> and V_<50>/v_<25> respectively. It had a tendency that A-aDO_2 increased with increasing closing volume and volume of isoflow. The results suggest that the volume of isoflow is likely to contribute to the detection of small airway disease.
