Asthma exacerbation severity can be quantified by comparing a patient’s current peak expiratory flow rate (PEFR) to their most recent personal best value. In the absence of a known recent personal best, this calculator can be used to estimate an expected “personal best.”.

For example, ‘I exercised on Tuesday’ or ‘I came into contact See your GP or asthma nurse if you’re having symptoms or you’re using your reliever inhaler three or more times a week, Asthma control test and peak expiratory flow rate: independent pediatric asthma management tools J Asthma . 2009 Dec;46(10):1042-4. doi: 10.3109/02770900903331101. If you have asthma, you can use a peak flow meter to measure your lung function, or peak expiratory flow (PEF), at home.

Peak flow meters are most helpful if you have A peak flow meter is a device used to measure how well your asthma is under control. The device measures air flow out of the lungs (peak expiratory flow rate or Start studying Asthma-Peak Expiratory Flow Rate (PEFR) Monitoring. Learn vocabulary, terms, and more with flashcards, games, and other study tools. During an asthma episode the airways in the lungs become narrow and the peak flow number may be low, showing that air is not moving easily through the lungs.

Write down your peak flow number in your asthma diary every day. A decrease in peak flow of 20 to 30 percent of your personal best may mean the start of an asthma episode. Your Asthma Action Plan may tell you to take your peak flow reading more often and to adjust your medicines. Use only one meter. Be sure to bring it to your asthma check-ups.

In asthma patients, peak expiratory flow rate (PEFR) measurement has been promoted as a useful tool for assessing airway obstruction and titrating therapy.

Peak Expiratory Flow Rate [PEFR] Peak expiratory flow rate is the maximal rate of air flow which is a subject can achieve by a forced expiration.

The decision to perform PEFR monitoring should be individualized for each patient. Although PEFR may aid emergency physicians during their evaluation and treatment of an adult patient with an acute exacerbation of asthma, the evidence does not support requiring PEFR monitoring for all adult patients. PEFR monitoring is a simple and cost‐effective means of determining the degree of airways obstruction. PEFR is a tool for monitoring patients with asthma, but it should not be used for the diagnosis of asthma.
