In plain words

What the trial is, and whether it could suit you

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,
