The incidence of Chronic Obstructive Pulmonary Disease is increasing every year, increasing the economic burden on the healthcare system. High frequency chest wall oscillation device is another airway clearance technique that according to several studies has a positive benefit in the respiratory symptoms experienced in cystic fibrosis and bronchiectasis patients.

Literature search in the Cochrane library, PubMed, Medline, PEDro SPORTDiscus, AMED, and CINAHL with the following keywords: physiotherapy, exercise, rehab, HFCWO, high frequency chest wall oscillation, positive pressure, COPD, Chronic obstructive pulmonary disease.

Four studies met the inclusion criteria. Overall, the studies showed positive results for the use of HFCWO in COPD patients of varying stages and acuteness. Only one study reported adverse effects.

HFCWO could be potentially added to the treatment of patients with COPD, however future studies need to be done using HFCWO in patients with COPD.
