Abstract

Lung functions particular reference to V. C., FEV₁, MVV, AVI, oxygen uptake. minute ventilation etc. was examined mostly as a pre-operative check up for the pulmonary resection who were admitted to National Medical Center during the period from 1960 to 1968. This study was intended to see a tendency of reduction the functions of the patients comparing to predected normal value in relation to some clinical factors of the disease. In the classification the extent of illness, slight group was those who had a cavitary lung lesion occupied less than one-third of lung field, that of moderate group being those of one-third to a half. and that of marked group being those of more than twothird. Vital capacity was within normal limit in many (62.5%) cases, and the wider extent of lesion had the more reduced vital capacity. It had a tendency to be reduced in right lung in marked group but not in slight and moderate groups in regard to left or right lung affected and same in longer duration in regard to duration of illness. One second forced expiratory volume percent was within normal limit in 46% of the cases and it had a similar tendency of reduction in extent of lesion and duration of illness as in vital capacity but no significant difference between left and right lung affected. In classification of ventilatory insufficiency, norma16, restrictive type 9. obstructive type 14, mixed type 3 was seen among the 32 cases. Maximum voluntary ventilation was within normal limit in 78% of the patients. There was no significant difference in the maximum voluntary ventilation to the excent of lesions and between left and right lung affected. Maximum voluntary ventilation had a tendency or reduction in over two years group in regard to duration of iIlness but not in less than one year and one to two year groups. Air velocity index was within normal Iimit in 88% of the cases and it was as simiIar tendency of changes as the maximum voluntary ventilation. Oxygen uptake, minute ventilation and vital capacity by bronchospirometry had no significant difference in the degree of reduction of the functions between left and right lung affected. But in regard to dividing the reduction rates into two categories (Iess than 40% and more than 40%) the severe reduction of the more than 40% was seen much more among the left lung group than in right. Ventilatory equivalent in the affected lung increased than in normal subject.
