One of the tests we perform at Sheboygan Internal Medicine Associates is spirometry. When you are experiencing shortness of breath, are a smoker, or there is concern you may have asthma, emphysema, or lung disease, a spirometry test measures the amount and speed of air that is inhaled and exhaled. During the test, you will inhale a deep breath and exhale as hard and long as you are able into a special mouthpiece. The test results allow us to properly diagnose your breathing issue.
