Summary

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.

Conditions

Interventions

BEHAVIORAL

Segmental Breathing Exercises

Deep breathing exercises focusing on specific lung segments to improve ventilation, lung expansion, and oxygenation in post open heart surgery patients.

BEHAVIORAL

Active Cycle Breathing Technique

A combination of breathing control, thoracic expansion exercises, and forced expiration technique to improve airway clearance and lung function.

OTHER

Standard postoperative care

Participants will receive routine postoperative care according to institutional protocols following cardiac surgery. This includes standard medical and nursing management such as oxygen therapy, pain control, monitoring of vital signs, and mobilization as tolerated, without additional structured respiratory physiotherapy interventions.
