Section I
Since 1953 applying Carlens catheter and Sanborn's respirometer, the author performed measurement test of broncho-lung's containing capacity on 6 healthy adult males. The results obtained are as follows.
1) The average total lung capacity on the right was 2, 260cc, 2, 155cc for the left lung, and the percentage of the total for both sides was 51.2% for the right lung and 48.8% for the left.
2) The rest situations of both lungs in the area of quantitative and qualitative functions were as follows. (Number in perenthesis indicates percentage of the total)
These figures indicate that the function of both lungs presumed to be identical and inductively and statistically no significant differences were noted.
3) The average total lung capacity was 4, 415cc and showed 9.8% decrease in supine position.
4) The measuring method of bronchial lung's capacity is a simple and safe method to measure pulmonary function.
Section II
In order to determine the correlation between chest X-ray findings and pulmonary function of patients with pulmonary tuberculosis, the measurement of bronchial lung's containing capacity was carried out. And results are 's follows.
1) Percentage of affected lung's vital capacity in unilateral focus group was 44.7% in right lung focus group and 40.9% in left lung focus group, indicating no particular difference of lung function between right and left lungs.
2) Lung capacity parallels oxygen intake among patients with parenchymatous focus. And in fresh focus in spite of noticeable X-ray findings the decrease of lung capacity remained slight, while in sclerosed old focus considerable decrease of lung capacity was noted.
3) In patients with bilateral diseases the roentgenographic location of involvement had no effect on function.
4) In the group with pleural involement the decrease of oxygen intake is slight in comparison with the decrease of lung capacity. The location and degree of pleural reaction has a noticeable effect on pulmonary function.
5) Pulmonary function is maintained in artificial pneumothorax of short duration. However, if collapse is prolonged, it will have an unfavorable effect on function.
6) In the group of artificial pneurnoperitoneum, no unfavorable effect on pulmonary function can be demonstrated.
