Abstract
Exacerbations of COPD are often characterized by increased mucus production that is difficult to treat and worsens patients' outcome. This study evaluated the efficacy of a chest physiotherapy technique (expiration with the glottis open in the lateral posture, ELTGOL) during acute exacerbations of COPD using as outcome measures sputum volume, length of hospitalization, reduction in dyspnoea (Borg score), improvement in quality of life (assessed by the St George Respiratory Questionnaire) and incidence of COPD exacerbations during follow up.
