Incentive Spirometer - What is it?

Taught patient / caregiver that an incentive spirometer (IS) is a device that measures how deeply you can inhale (breathe in). It helps you take slow, deep breaths to expand and fill your lungs with air. This helps prevent lung problems, such as pneumonia. The IS is made up of a breathing tube, an air chamber, and an indicator. The breathing tube is connected to the air chamber and has a mouthpiece at the end. The indicator is found inside the device.
