  1. Measurements were taken at inclusion and at the end of the first intrapulmonary percussive ventilation session (post IPV session; in the thirtieth minute). aOxygen flow was not changed between both periods and was 2.0 ± 0.5 l/min. IPV, intrapulmonary percussive ventilation; RR, respiratory rate; NS, not statistically significant.
