Peak Flows: Measuring your peak flows with an incentive spirometer at home is a great and safe way for you and your doctor to monitor your asthma over time. Occasional pulmonary function testing in the office provides valuable information, but tracking peak flows over times also lets us know how well controlled your asthma is. If you want to improve lung function try exercising 4-5 times per week.
