Measurement of PEFR requires training to correctly use a meter and the normal expected value depends on the patient's sex, age, and height. It is classically reduced in obstructive lung disorders such as asthma. Due to the wide range of 'normal' values and the high degree of variability, peak flow is not the recommended test to identify asthma.

Topputandningsflöde (engelska: peak expiratory flow, PEF) är ett mått på det högsta flödet man kan blåsa ut med. Det mäts i liter/minut eller liter/sekund.

PEF monitoring in patients with asthma will be reviewed here. Other aspects of asthma diagnosis Current practice guidelines for the treatment of an acute asthma exacerbation, such as in the emergency department (ED) setting, recommend that objective measures of pulmonary function such as peak expiratory flow (PEF) and FEV1 be used. Mechanical peak flow meters are most commonly used in the ED setting since they are inexpensive and easy to use. Serial PEF monitoring is currently recommended as a confirmatory test for occupational asthma by several guide-lines [12–14], but not all diagnostic centers have agreed about its value. Previous reviews of diagnostic methods for occupational asthma have been published [12, 15] but, to our knowledge, this is the first systematic review of Spirometry and Peak Flowmetry were done during the methacholine challenge test, then FEV1 and PEF were recorded. From 120 patients, 47 patients [39.2%] were male and 73 [60.8%] were female. Thirty three [27.5%] patients showed a >/= 20% decrease in FEV1, while 35 … Fifty asthma patients whose PEF values had been in the.

The cough variant of asthma [CVA] is a latent form of the disease. The aim of this study is to compare the decreasing rates of FEV1 and PEF during the methacholine challenge test. In this study, we tested a total of 120 patients [14-65 years old], whom were referred to the respiratory clinic with complaints of chronic cough, using normal chest and sinus x-ray and spirometry. 2 dagar sedan · The unreliability of PEF diaries is probably one of the main reasons why PEF monitoring does not contribute as much to the success of asthma self management as one would assume intuitively. 25 Recently, we showed that up to 50% of entries in PEF diaries of affluent white asthmatic children whom we considered to be “model patients” were either invented or falsified.

In patients with asthma, the PEF percent predicted correlates reasonably well with the percent predicted value for the forced expiratory volume in one second (FEV 1) and provides an objective measure of airflow limitation when spirometry is not available . PEF monitoring in …

The purpose of the treatment is to keep the values of PEF between 100-80 % of personal norm of the patient, values between 80-60 % represent mild airway obstruction, values between 60-45 % moderate airway obstruction and values below 45 % indicate severe airway obstruction. PEF values of 50-79% of predicted or personal best signify need for immediate treatment with an inhaled short acting beta agonist (SABA), PEF values below 50% indicate the need for immediate medical care, and PEF values below 35% indicates a severe life threatening episode.

Values for peak flow are quoted in litres per minute. Normal values lie between 400-600 l/m. In asthmatics values lie between 200-400 l/m (100 l/m in severe predictiveness of PEF is obtained when values 80% of predicted for age are considered normal.
