LUNG VOLUMES OF NORMAL AND ASTHMATIC CHILDREN

[摘要] Measurements of the various lung volumes were carried out with 27 normal children, 21 asthmatic children and 4 with allergic rhinitis. The asthmatic children had increases in functional residual capacity and residual volume.There was a significant increase in the time required for intrapulmonary mixing of gas in the asthmatic subjects.A biphasic character to the "wash-out" curves in both normal and asthmatic subjects was shown.It was considered, though not proved, that the increases in lung volume were due to the presence of bronchial obstruction.
