PurposeThe 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.BackgroundChest physiotherapy and HFCWO are routinely used after lung transplant to attenuate dyspnea, increase expiratory flow, and improve secretion clearance.MethodsIn a two-group experimental, crossover design with repeated-measures, 45 lung transplant recipients (27 single, 18 bilateral; 64% male; mean age, 57 years) 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.ResultsThere 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).ConclusionsPreliminary 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.Copyright © 2014 Elsevier Inc. All rights reserved.
