Using an incentive spirometer

Many people feel weak and sore after surgery and taking big breaths can be uncomfortable. A device called an incentive spirometer can help you take deep breaths correctly.

By using the incentive spirometer every 1 to 2 hours, or as instructed by your provider, you can take an active role in your recovery and keep your lungs healthy.

To use the spirometer:

• Sit up and hold the device.
• Place the mouthpiece spirometer in your mouth. Make sure you make a good seal over the mouthpiece with your lips.
• Breathe out (exhale) normally.
• Breathe in (inhale) slowly.

A piece in the incentive spirometer will rise as you breathe in.

• Try to get this piece to rise as high as you can.
• Usually, there is a marker placed by your provider that tells you how big of a breath you should take.

A smaller piece in the spirometer looks like a ball or disk.

• Your goal should be to make sure this ball stays in the middle of the chamber while you breathe in.
• If you breathe in too fast, the ball will shoot to the top.
• If you breathe in too slowly, the ball will stay at the bottom.

Hold your breath for 3 to 5 seconds. Then slowly exhale.

Take 10 to 15 breaths with your spirometer every 1 to 2 hours, or as often as instructed by your provider.

These tips may be helpful:

• If you have a surgical cut (incision) in your chest or abdomen, try holding a pillow tightly to your belly while breathing in. This will help ease discomfort.
• If you do not make the number marked for you, do not get discouraged. You will improve with practice and as your body heals.
• If you start to feel dizzy or lightheaded, remove the mouthpiece from your mouth and take some normal breaths. Then continue using the incentive spirometer.
