Differences in the Peak Inspiratory Flow in Manual Breathing Assist and Rib Springing Techniques

Abstract

Purpose: The present study aimed to compare the tidal volume and the peak inspiratory flow during manual breathing assist and rib springing in the lower chest. Method: Twenty-three healthy adult men were included. The manual breathing assist and rib springing procedures were performed by a physical therapist familiar with respiratory physical therapy. Measurement conditions were as follows: the maximum tidal volume was measured during quiet breathing, and while using manual breathing assist, and during rib springing. The peak inspiratory flow was measured 3 times each during manual breathing assist and rib springing, and the maximum value was used. Results: The tidal volume increased significantly during manual breathing assist and rib springing in comparison to quiet breathing. There was no significant difference in the tidal volume in manual breathing assist and rib springing. The peak inspiratory flow during rib springing was significantly higher compared to that during manual breathing assist. Conclusion: Our results suggest that the rib springing was able to increase the peak inspiratory flow by about 1.6 times in comparison to the manual breathing assist.
