 Incentive Spirometer exercises help keep lungs open and may prevent post-operative breathing complications. By using the Incentive Spirometer, you take an active role in your recovery. The first time you use your Incentive Spirometer, you'll need to expand the tubing and connect it to the outlet on the outside of the base. Slowly position yourself in an upright, seated position. Place the mouthpiece in your mouth and seal your lips tightly around it. Breathe in slowly and as deeply as possible. Notice the piston rising toward the top of the column. The indicator will rise and should remain between the two arrows. Hold your breath as long as possible. Then, exhale slowly and allow the piston to fall to the bottom of the column. Rest for a few seconds and repeat. After surgery, do these exercises at least 10 times every hour while you are away or as directed by your physician. Position the marker on the left side of the spirometer to show your best effort. Use the marker as a goal to work toward during each slow, deep breath. Do not get discouraged if you do not reach the same number as you did before surgery. You will improve as you heal. After each set of 10 deep breaths, cough to be sure your lungs are clear. If you have an incision, support your incision when coughing by placing a pillow firmly against it.
