In order to compare divers with non-divers and to evaluate the Navy divers' pulmonary function, 101 divers and 99 non-divers have been tested for our study.
At least, pulmonary function test based on forced expiratory volume curve have been tried 3 times, and the best results were used for evaluating FVC, FEV0.5, FEV1, %FEV0.5, %FEV1, FEF200-1200ml, FEF25-75%, and FEF25-75%. After the comparison of
general
characteristics and pulmonary function between diving and non-diving group, we check out the differences by smoking and diving career. @ES And we find out the correlation among the study variables and the results were as follows:
@EN 1. The value of FEF200-1200ml was significantly higher in diving group than in non-diving group.
2. The values of FVC, FEV0.5, FEV1, %FEV0.5, %FEV1 and FEF24-75% had no significant differences between diving and non-diving group.
3. Smoking divers had higer FEF200-1200ml than non-smoking ones.
4. 1-2 year diving group had high %FEV0.5 and %FEV1 values (p<0.05, p<0.01), and significant differences were not found in FVC, FEV0.5, FEV1, FEF200-1200 and FEF25-75%.
5. There were significant correlations between pulmonary function and age and height.
