Study on Time-Effect Relation in Acupuncture of Feishu Point Improving Pulmonary Function

In the present paper, improving effects of different needle-retained periods on pulmonary function in patients of diseasses of the respiratory system were investigated when acupuncture was given at Feishu Point(BL 13). Results indicated that acupuncture of Feishu point could improve markedly pulmonary function. The acupuncture effect was seen when the needle was retained for 20 min and it was the most obvious when the needle was retained for 40 min,but it reduced to some extent when the needle retained for 60 min. It is suggested that different needle-retained periods have different improving effects on pulmonary function.
