![]() This simple device measures what’s called your “peak expiratory flow,” or PEF. To monitor how well your asthma is controlled, your doctor may suggest you use a peak flow meter. For more information about the Asthma Monitor, talk to your doctor, pharmacist, or a Certified Respiratory Educator. It is important that you perform these measures with your healthcare provider before your self monitoring begins to ensure you are doing the measures correctly. On the other hand, an increase in measured values will indicate increased asthma control or response to controller medications. If monitoring shows a decrease in these values over time, this may show that your asthma is worsening, meaning a loss of asthma control. Using the Asthma Monitor for these measurements allows you to monitor your asthma on a day to day basis and will help determine the effectiveness of prescribed anti-inflammatory (controller) medications. These results can be shared with your health care provider by sending the obtained measurements by e-mail or by bringing the results to your next appointment. The measurements are made and recorded once or twice daily and can be easily downloaded using special computer software. ![]() These tests may be similar to ones you perform at your physicians’ office. If asthma is present with airway inflammation or bronchoconstriction, the peak flow and/or FEV1 levels will be lower as there is airway narrowing.
