Abstract
Jansang S, Kietinun S, Sriyakul K, Tungsukruthai P, Krajarng A, Srisuma S. Effects of Pursed-Lip Breathing by Using a Windmill Toy after 12-Week Training on Maximum Oxygen Efficiency in Chronic Obstructive Pulmonary Disease Patients. JEPonline 2021;24(4):96-108. Chronic obstructive pulmonary disease (COPD) is an illness that cannot be cured, but breathing capacity can be restored to function effectively. The purpose of this study was to measure the effects of the pursed-lip breathing exercises by using a windmill toy on the maximum oxygen use before and after the intervention and the exertion conditions during the breathing exercises in COPD patients with mild to moderate severity level. This study was a randomized controlled trial. The sample was COPD patients admitted to the COPD clinic of the Pulmonary Medicine Clinic in Rajavithi Hospital, Bangkok, Thailand. A total number of 46 participants were randomly divided into 2 Groups: (a) the Intervention Group (n = 23); and (b) the Control Group (n = 23). The Intervention Group received pursed-lip breathing exercises using a windmill toy for 45 min·session-1, 1 session·d-1, 3 times·wk-1 for 12 weeks while the Control Group received the standard medical care. The measurement tools included Cardiopulmonary Exercise Testing (CPET) to measure cardiopulmonary endurance and St. George’s Respiratory Questionnaire (SGRQ) to evaluate the quality of life in COPD patients. The descriptive statistics consisted of the student's paired t-test and ANOVA. The results showed that both groups improved significantly in respiratory performance. The cardiopulmonary exercise testing results for variables divided into COPD categories in both groups increased significantly (P<0.05). The results demonstrated the positive effects of the pursed-lip breathing exercises by using a windmill toy, an easy-to-train, effective, and user-friendly method in COPD patients, which helped improve breathing efficiency leading to better quality of life.
