A peak flow meter (PFM) is a device that a person blows into as hard as possible to get a reading called the “peak flow rate.” This number can indicate how well or how poorly air is moving through your airways. This is helpful because people usually get used to their own breathing patterns and can’t always tell when they are getting worse. A low peak flow rate can be an early warning sign of an upcoming asthma attack, giving you an opportunity to take preventive steps to regain control of your asthma.
Already have a peak flow meter?
If you haven’t been using your PFM regularly, we encourage you to try taking regular peak flow readings for one month as you track your symptoms using your asthma diary. This may provide you with useful insight into your own breathing patterns, which may prove to be helpful as you research and observe your current asthma management routine.
Don’t have a peak flow meter?
If you don’t currently use a PFM, that’s okay! You can still manage your asthma effectively by paying close attention to other early warning signs, tracking your symptoms using your asthma diary, and understanding your asthma triggers.If you are interested in learning more about how you can get a PFM, you should check the benefit guide of your health insurance plan or call the company’s customer service department. Often, PFMs are categorized as durable medical equipment (DME), and coverage varies by insurance company and individual health insurance plan.
