Incentive spirometry is designed to mimic natural sighing or yawning maneuvers and to help lung expansion. What is a key clinical purpose of incentive spirometry?

• A. Prevents atelectasis
• B. Improves cough strength
• C. Reduces airway resistance
• D. Delivers bronchodilators

Answer: (A)

The main concept here is using a tool to maximize lung inflation to keep the airways open. Incentive spirometry encourages slow, deep breaths that expand the lungs and recruit or reopen small airways that can collapse when breathing is shallow. By increasing the volume of air drawn into the lungs and maintaining repeated, sustained inflation, it helps prevent atelectasis, the collapse of parts of the lung that can occur after surgery or during periods of reduced breathing effort. This approach supports better ventilation and oxygenation by keeping alveoli from collapsing and improving overall lung compliance. It doesn’t primarily increase cough strength, reduce airway resistance, or deliver bronchodilators. Those effects involve different techniques or medications, whereas the device’s key clinical purpose is to prevent atelectasis through improved lung expansion.
