Usual ACT HFCWO
Baseline During treatment 30 min after treatment Baseline During treatment 30 min after treatment
FEV1% predicted 39.1 (16.9) NA 38.9 (17.1) 38.9 (16.8) NA 39.2 (16.7)

Data are presented as mean (SD).

ACT, airway clearance technique; FEV1, forced expiratory volume in 1  s; HFCWO, high frequency chest wall oscillation; NA, not applicable; SpO2, pulsed arterial oxygen saturation.
