A peak flow meter is a simple, easy-to-use device that measures how fast you can exhale a lungful of air. It helps manage asthma and can even indicate when your asthma is getting worse before you have symptoms.

Oct 23, 2024 · A peak flow meter is a portable, inexpensive, hand-held device used to measure how air flows from your lungs in one fast blast. In other words, the meter measures your ability to push air out of your lungs.

Peak flow measurement is a quick test to measure air flow out of the lungs. The measurement is also called the peak expiratory flow rate (PEFR) or the peak expiratory flow (PEF). Peak flow measurement is mostly done by people who have asthma or a long-term (chronic) lung disease.

The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.

Peak Expiratory Flow (PEF), likewise called Peak Expiratory Flow Rate (PEFR) is an individual’s maximum speed of expiration, as measured with a peak flow meter. This is a small, hand-held device utilized to keep an eye on a person’s ability to breathe out air.

Mar 1, 2014 · A step-by-step guide to explaining and performing peak expiratory flow rate (PEFR) measurement, with an included video demonstration.

Oct 6, 2024 · Peak expiratory flow (PEF) measurement is critical in asthma management, particularly when spirometry is unavailable. Measured using widely accessible peak flow meters, PEF offers an objective assessment of airflow limitation and helps guide asthma control and treatment decisions.

Aug 31, 2018 · The peak expiratory flow rate (PEFR) test measures how fast a person can exhale. The PEFR test is also called peak flow.

You measure peak flow by taking a full breath in and blowing out as hard and fast as you can into a small hand-held device called a peak flow meter. Your peak flow score is also called your peak expiratory flow (PEF).

Aug 8, 2023 · What Is a PEFR Test? A peak expiratory flow rate (PEFR) measures how effectively you exhale. Also called a peak flow meter, this handheld device helps you document the amount of air and...
