Background: Bronchiectasis is a chronic inflammatory condition characterized by bronchial dilatation. Coughing and sputum development are common in patients, as well as repeated exacerbations. The purpose of this study: wasto evaluate the response of arterial blood gases (PaO2 and PaCO2) to Aerobika oscillating positive expiratory pressure training in patients with bronchiectasis.Methods: The study included sixty diagnosed bronchiectasis patients of both sexes (twenty-four males and thirty-six females) with ages ranging from 45 to 65 years.They were recruited from the Abasseya Chest Hospital.They were able to comprehend and obey verbal instructions. The patients were divided into two categories at random: Group I (study group): Thirty patients received their medications and were trained with the Aerobika (OPEP) device. Group II (control group): Thirty patients received their medications only.The blood gases (PaO2 and PaCO2) were measured before and at the end of the program. Six-minute walk test (6MWT) and percent predicted six-minute walk distance (% predicted 6MWD) were carried out before and after interventions to determine the patient{u2019}s functional capacity, and ST. Georges respiratory questionnaire (STGRQ) was also performed. Results: The study group which used the Aerobika device showed a statistically significant improvement in blood gases (PO2 and PCO2), quality-of-life questionnaire (STGRQ) score, and functional exercise capacity tests 6MWT and % predicted 6-MWD (P<0.5)
