Simple breathing tools may speed lung recovery after heart surgery
NCT ID NCT07337746
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether two breathing devices—Acapella and incentive spirometry—can improve lung function and blood oxygen levels in 100 adults recovering from coronary artery bypass surgery. Participants use the devices twice daily before and after surgery. The goal is to see which device works best to help lungs recover and prevent complications.
