This randomized clinical trial aims to compare the effectiveness of Active Cycle of Breathing Techniques combined with Incentive Spirometry (ACBT + IS) versus High-Frequency Chest Wall Oscillation (HFCWO) in patients undergoing thoracic surgery. Postoperative pulmonary complications such as reduced lung function, ineffective cough, and sputum retention are common after thoracic procedures and can delay recovery. A total of 42 participants will be randomly allocated into two groups: one receiving ACBT with Incentive Spirometry and the other receiving HFCWO, along with standard postoperative care. Outcomes including cough effectiveness, sputum clearance, pulmonary function tests, and patient satisfaction will be assessed at baseline, postoperative day 3, and day 5. The study aims to determine the more effective airway clearance technique to improve respiratory outcomes and enhance patient recovery following thoracic surgery.
Adults aged 18-40 years
Patients scheduled for elective thoracic surgery (e.g., lobectomy, pneumonectomy, thoracotomy, or VATS)
Hemodynamically stable in the postoperative period
Cognitively and physically able to perform breathing exercises and use devices (incentive spirometer/HFCWO vest)
Pre-existing severe pulmonary diseases (e.g., COPD, cystic fibrosis, bronchiectasis)
Contraindications to HFCWO (e.g., recent rib fractures, chest wall trauma, unstable cardiovascular status)
Cognitive, neuromuscular, or musculoskeletal impairments limiting participation in interventions
Prolonged mechanical ventilation (>24 hours postoperatively)
