Purpose: The aim of this study is to compare the effects of chest physiotherapy (CPT) and high-frequency chest wall oscillation (HFCWO) on lung function in lung transplant recipients. Background: Chest physiotherapy and HFCWO are routinely used after lung transplant to attenuate dyspnea, increase expiratory flow, and improve secretion clearance. Methods: In a two-group experimental, crossover design with repeated-measures, 45 lung transplant recipients (27 single, 18 bilateral; 64% male; mean age, 57years) were randomized to receive CPT at 10:00 AM and 2:00 PM followed by HFCWO at 6:00 PM and 10:00 PM (n=22) or vice versa (n=23) on postoperative day 3. Dyspnea (modified Borg score), Spo2/FiO2, and peak expiratory flow (PEF) were measured pre-treatment and post-treatment. Data were analyzed using chi-square tests, t tests, and linear mixed effects models. Results: There was no statistically significant treatment effect for dyspnea or PEF in patients who received HFCWO versus CPT. However, there was a significant treatment effect on the Spo2/FiO2 ratio (p<0.0001). Conclusions: Preliminary results suggest that lung function (measured by Spo2/FiO2) improves with HFWCO after lung transplantation. Although dyspnea and PEF did not differ significantly between treatment types, HFCWO may be an effective, feasible alternative to CPT.
