What is the proper sequence to use an incentive spirometer?

• A. Sit upright; Exhale; Insert mouthpiece; Inhale for 3 seconds and hold for 10 seconds
• B. Sit upright; Inhale; Insert mouthpiece; Exhale
• C. Exhale; Sit upright; Inhale; Hold breath
• D. Insert mouthpiece; Sit upright; Exhale; Inhale

Answer: (A)

The main idea is to promote a slow, deep breath to maximize lung expansion and keep the small airways open, which helps prevent atelectasis after surgery or periods of limited activity. The sequence starts with sitting upright so the chest and diaphragmatic mechanics can expand fully. Exhaling first prepares the lungs for a deeper inhalation by bringing the lungs to a ready volume. Placing the mouthpiece ensures a proper seal so all air goes through the device and you can gauge your effort accurately. Then inhale slowly through the mouthpiece for a controlled breath, raising the device’s indicator, and hold the breath for several seconds to give the expanded air time to open alveoli and improve gas exchange. After that, exhale normally and repeat as prescribed. This order supports effective use of the incentive spirometer and maximizes the lung-expansion goal.
