Peak expiratory flow (PEF) measures how much air you or your child can breathe out using the greatest effort. It is used in the monitoring and treatment of 

A peak flow meter is a handheld device that measures how well air moves out of your lungs. During an asthma episode, your airways often narrow. A peak flow meter can measure this narrowing hours, even days, before you have any asthma symptoms.

Normal values for peak expiratory flow (PEF), shown on EU scale. Peak expiratory flow (PEF) is the maximal flow (or speed) achieved during the maximally forced expiration initiated at full inspiration, measured in liters per minute or in liters per second.

Asthma is a common lung problem that causes breathing difficulties for people of all ages. The severity of an asthma attack varies from person to person and even event to event. Luckily, most people with asthma control the condition and its If you have asthma, it’s important to know about medicines that might cause problems before you take them. Certain medicines might make your asthma worse.

It is important to remember that  For the individual paired measurements, the mean differences between PEF and FEV1 percentage predicted were calculated. Measurements of lung function  An individual's lung and airway function can be assessed by using a hand held peak flow meter. This measurement is often used to diagnose and monitor asthma. The change in scale for peak flow meters will result in PEF readings that are is frequently one-third or more below your best it may mean that your asthma is  Dec 10, 2016 If you have an asthma flare-up that makes your breathing tubes squeeze Ask them how to understand what your peak flow scores mean.

A chart called a 'nomogram' can be used to estimate your predicted peak flow if you are male or female, your age and height. It is important to remember that 

Peak flow rate primarily reflects large airway flow and depends on the voluntary effort and muscular strength of the patient. Mean changes in PEF across morning/day shifts were compared between workers with occupational asthma, confirmed using specific challenge testing, and non-working asthmatics. Individuals were divided into a development set, used to identify the optimum cross-shift change for diagnosing occupational asthma, and an evaluation set, used to test the sensitivity and specificity of this value.

Peak expiratory flow (PEF) monitoring is often used to establish the relationship between occupational exposure and asthma. FEV 1 has been found to be a better physiologic index than PEF in the measurement of airflow obstruction. The aim of this study was to compare the accuracy of serial monitoring of PEF and FEV 1 in the diagnosis of occupational asthma.

Peak flow can pick up changes in your airways, sometimes before you have any symptoms. of FEV1 in mL divided by the PEF in L per min. If this is above 8, then upper airway obstruction is likely (figure 2) [4, 5]. This ratio is another way of highlighting discordance between PEF and FEV1. Low PEF, low FEV1 and low FEV1/FVC This pattern characterises intrapulmonary airflow obstruction, which is found in asthma, chronic Here, once-daily tiotropium significantly improved morning and evening PEF (p < 0.001), FEV1 (p = 0.004), and asthma control as determined by the Asthma Control Questionnaire (ACQ; p < 0.001) compared to doubling of the ICSs. 2019-12-19 · Peak expiratory flow, or PEF, is the amount of air you can quickly expel from your lungs. Used to measure lung function in people with asthma, PEF can be tested at home by blowing out as hard and The most important and readily available test to evaluate the severity of an asthma attack is the measurement of peak expiratory flow (PEF).
