What is the importance of incentive spirometry?

• A. Improves lung function
• B. Helps patients improve the functioning of their lungs
• C. Cures pneumonia
• D. Eliminates the risk of atelectasis

Answer: (B)

Incentive spirometry focuses on training the patient to take slow, deep breaths to expand the lungs and keep airways open. By providing a visual target and feedback, it helps achieve sustained maximal inspirations, which restore lung volumes after surgery or during illness and improve overall lung function. This practice enhances ventilation and helps mobilize secretions, reducing the likelihood of collapsed areas in the lungs. It is not a cure for pneumonia, and it does not eliminate the risk of atelectasis entirely, but it is a key preventive tool to improve how the lungs function.
