Effect of Different Breathing Techniques on Dyspnea and Cardiopulmonary Parameters Among Patients After Open Heart Surgery
Effect of Segmental Breathing Versus Active Cycle Breathing Techniques on Dyspnea and Cardiopulmonary Parameters Among Patients After Open Heart Surgery: Randomized Controlled Trial.
Source: ClinicalTrials.gov · Last updated 18 May 2026
Brief summary (registry, in English)
Open heart surgery is often associated with postoperative pulmonary complications, reduced lung expansion, dyspnea, and impaired cardiopulmonary function. Breathing exercises are commonly used after surgery to improve lung ventilation, enhance oxygenation, and support respiratory recovery. However, limited evidence is available comparing the effectiveness of segmental breathing exercises and active cycle breathing technique (ACBT) in patients after open heart surgery. This randomized controlled trial will compare the effects of segmental breathing exercises and ACBT on dyspnea and cardiopulmonary parameters in adults undergoing open heart surgery. Participants will be randomly assigned to either the segmental breathing exercise group, the ACBT group, or the standard care group during the postoperative period following extubation. Cardiopulmonary parameters, including oxygen saturation, respiratory rate, heart rate, and blood pressure, as well as dyspnea severity and postoperative pulmonary complications, will be assessed before and after the interventions. The findings of this study may help identify the most effective breathing exercise technique for improving respiratory outcomes, reducing postoperative pulmonary complications, and supporting evidence-based postoperative rehabilitation after cardiac surgery.
