| Research Abstract |
[Experiment 1] In this study we examined the potential benefits of incentive spirometry respiratory training on the ventilatory function of healthy women. Participants did 4 sets of breathing exercises a day, with half the participants doing 10 repetitions per set and the other half doing 30. Each group was further subdivided into training periods of 2, 4, 6, 8, or 10 days. We found that when pre- and post-training breathing capacity and vital capacity as percent of predicted were compared, a significant increase was seen in both the 10 reps/set/10-day group and the 30 reps/set/10-day group, but that the increase was significantly larger in the 30 reps/set/10-day group. In addition, peak expiratory flow rate for the 30 reps/set/10-day group significantly increased. These results suggest that, for incentive spirometry breathing exercises, more than 10 reps per set are necessary to significantly improve ventilatory function, and that an improvement in breathing capacity does not necessar

[Experiment 2] The purpose of this study was to determine the efficacy of incentive spirometry in improving postoperative ventilatory function. The intervention group performed 4 sets of breathing exercises in one day, and the exercise was repeated 10 times per set. The intervention period was from the day before surgery to 10 days after surgery, and ventilatory function was measured 1, 5, and 10 days postoperatively using an electronic spirometer. We found that breathing capacity and percent breathing capacity significantly decreased one day postoperatively compared to before surgery in the control group. Furthermore, values for these parameters were significantly lower in the control group compared to the intervention group. These findings suggest that postoperative incentive spirometry can improve ventilatory function and that if sustained maximum inspiration can be maintained, 4 sets of breathing exercises at 10 repetitions per set daily may improve ventilatory function.
