Which device is commonly used to promote lung expansion and airway clearance after surgery?

• A. Incentive spirometer.
• B. Nebulizer with bronchodilator.
• C. Chest drainage unit.
• D. Pulse oximeter.

Answer: (A)

Promoting lung expansion after surgery is crucial to prevent atelectasis and help clear secretions. The incentive spirometer directly encourages deep, sustained breaths, which increases lung volumes, expands collapsed alveoli, and stimulates diaphragmatic movement. This positive-pressure, feedback-guided breathing trains patients to take larger inspiratory efforts, aiding airway clearance and overall ventilation during the recovery period. Other devices have different primary roles: a nebulizer with bronchodilator delivers medication to open airways but isn’t specifically used to promote lung expansion; a chest drainage unit removes air or fluid from the pleural space after thoracic surgery or trauma; a pulse oximeter monitors oxygen saturation without actively expanding the lungs.
