[The effects of incentive spirometry on pulmonary functions].
The effects of incentive spirometry on pulmonary functions were studied in 46 normal adults of advanced age ('N' group) and 42 patients with chronic pulmonary emphysema ('E' group). Subjects of the both groups carried out deep breathing exercises by using incentive spirometry, 'Souffle', for five minutes, five times daily for four weeks. Pulmonary functions and arterial blood gases were measured at the start of exercise program, and at two and four weeks after the start. Both groups showed significant increases in VC, FEV1.0, peak expiratory flow, the flow at 75 percent VC (V75), maximal voluntary ventilation and PaO2, and a significant decrease in A-aDO2 at both two and four weeks after the start. In addition, V25 increased significantly in 'E' group. It is concluded that 'Souffle' is one of the useful preoperative respiratory managements for elderly patients and those with chronic pulmonary emphysema.
