Do you suffer from asthma? Do you often experience a shortness of breath and feel uncomfortable after a walk or run? Have you spoken to your doctor about it and want to monitor the functioning of your lungs? If you can relate to the above situations, maybe you need a peak flow meter. Read on to know all about the use of a peak flow meter and how it can help you.
What Is A Peak Flow Meter?
A peak flow meter is a device used by asthma patients or those with breathing problems to measure how well the air is moving in and out of their lungs. It is an inexpensive and portable device that is also very user-friendly. Measuring the air flow using the peak flow meter can help you manage your asthma symptoms better and avoid the possible onset of an asthma attack.
How Does A Peak Flow Meter Work?
Before you use the peak flow meter, you have to inhale deeply and fill up your lungs with air. A peak flow meter measures the ‘peak expiratory flow’ or the PEF that is the speed at which the air comes out of your lungs when you exhale into it. By monitoring your peak expiratory flow, you can find out if there is any improvement in your lung functioning or not.

Why Should You Use A Peak Flow Meter?
Using a peak flow meter to monitor the functioning of your lungs is a sure-shot way of managing your asthma. If your PEF improves, you will know that the symptoms of your asthma are under control. On the other hand, if your reading deteriorates, you will know when your symptoms are worsening, and you need to schedule a visit to your doctor.
When you have an asthma attack, your airways tighten and narrow making the air flow difficult. If you use the peak flow meter to track your breathing, the readings will alert you if your airways are becoming narrow. It can happen hours or even days before other symptoms of asthma strike. Thus, using the peak flow meter will help to alert you to watch out for a possible asthma attack.
It is always a good idea to use your peak flow meter along with your regular asthma medication. It will help you stay prepared and know exactly when you need to use your inhaler to prevent an asthma attack. It can also alert you to take any precautionary asthma medicine. Using both the medication and the peak flow meter together will help you take preventive action in time and avoid an asthma attack.
Using the peak flow meter can help you in the following ways:
- It can help you identify all the elements that trigger an asthmatic reaction in you.
- The peak flow meter can also help you understand if your medications and asthma management plan are working the way they should.
- By reading the results on the peak flow meter, you will know when it is time for you to change your medication in case they are not as effective as they are supposed to be.
- The readings from the peak flow meter will also alert you when you should take your preventive medicine.
- One of the biggest ways in which the peak flow meter can help you is by alerting you to a possible health scare. You will know in advance when your symptoms are indicative of an asthma attack, and you can prevent or handle it better.
