What is the primary purpose of incentive spirometry after thoracic surgery?

• A. To prevent atelectasis by promoting deep breathing
• B. To measure lung volume changes
• C. To evaluate chest wall mobility
• D. To determine patient's pain level

Answer: (A)

Incentive spirometry after thoracic surgery is used to prevent atelectasis by promoting deep, slow breaths that achieve sustained maximal inspiration. The deep breaths expand the alveoli, reopen any collapsed areas of the lungs, and improve overall ventilation, which helps reduce postoperative pulmonary complications. While the device provides feedback on volume, the main purpose is therapeutic—to keep the lungs expanded and oxygenation better as the patient recovers. It isn’t primarily meant to measure lung volumes, evaluate chest wall mobility, or gauge pain—those are not the primary goals of this device. Use it with adequate pain control, and perform several deep-breath sessions per hour while awake to maximize lung expansion and clearance of secretions.
