説明

It was mentioned that characteristic of interstitial pneumonia during exercise is high respiratory frequency and high ratio of tidal volume to inspiratory capacity (VTsuneo/IC). We investigated the change in respiratory frequence and tidal volume in patients with interstitial pneumonia during exercise compared to those of pulmonary emphysema.<br>The results showed that respiratory frequency and VT/IC increased in patients with interstitial pneumonia compared to pulmonary emphysema, but thera were no significant difference in VT/IC between interstitial pneumonia and pulmonary emphysema.<br>Frequency/tidal volume (f/VT) ratio, rapid shallow index, was elevated in interstitial pneumonia compared to that in pulmonary emphysema (p=0.0041). We thought that high value was due to low pulmonary compliance and the accelation of sympathetic nerve by intestitial edema.<br>We thought characteristic finding of interstitial pneumonia during exercise was high value of f/VT and high respiratory frequency.
