How to use a manual incentive spirometer

When you use an incentive spirometer, you'll breathe in air through a tube that is connected to a large air column containing a piston or ball. As you breathe in, the piston or ball inside the column moves up. The height of the piston or ball shows how much air you breathed in. You may feel lightheaded when you breathe in deeply for this exercise. If you feel dizzy or like you're going to pass out, stop the exercise and rest.

Each time you do this exercise, keep track of your progress by writing down how high the piston or ball moves up the column. This will help you and your doctor know how well your lungs are working.

  1. After you've taken the recommended number of breaths, try to cough a few times. This will help loosen any mucus that has built up in your lungs. It will make it easier for you to breathe.

  2. If you just had surgery on your belly or chest, hold a pillow over your incision when you cough. This will support your belly or chest and reduce your pain.

  3. Repeat these steps as many times a day as your doctor tells you to.
