RESULTS: The three motions of <Respiratory rehabilitation Exercise for Pulmonary Fibrosis >were decomposited into six motions and were measured by VRI QLD value (%). It is concluded that when whole lung motion with deep breath, QLD average of both lower lung was obviously higher, unilateral lung was higher, bilateral lung was higher than that of quiet breathing. After one times exercise, heart rate of normal persons had a significant change from the previous, no significant changes in pulse oxygen saturation. After one minute rest, there was no significant difference in heart rate from previous data, no serious arrhythmia accured during exercise. We followed 19 cases of IPF (10 cases of exercise group, 9 cases of control group) without acute aggravating for 3 months. The FVC of lung function were measured and reveal that exercise training group were increased than before exercise, QLD visible image contrast before and after exercise, the SGRQ scores after exercise had obvious drop and had significance difference between before and after exercise (p=0.017), 6MWT walking distance of exercise group were increased, DLCO falling slower in exercise group than control group. Breathing exercise during exercise had lead to cough, chest tightness could be tolerated.
