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. 26 In clinical practice

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.

Mätning av PEF kan inte ersätta spirometri eftersom PEF mäts under trapped gas in the lungs during provoked asthma followed by beta-2-receptor stimulation.

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.

At each follow-up visit, reinforcement regarding the usefulness of PE F monitoring was given. The specialized educator also reviewed the diary card to check whether the patient had increased his asthma medication when PEF dropped. Abstract. Background: Asthma and COPD (Chronic Obstructive Pulmonary Disease) attacks are frequently seen in emergency departments.While giving oxygen to these patient groups we generally use standard masks. We compared the standard mask with diffuser mask which was an open-style oxygen mask in reducing carbon dioxide levels and increasing the PEF (peak expiratory flow) values. Using the Asthma Monitor for these measurements allows you to monitor your asthma on a day to day basis and will help determine the effectiveness of prescribed anti-inflammatory (controller) medications.

A child’s personal best value of PEF one or two years ago may be below the predicted PEF value for present body height. In this way asthma exacerbation may be overlooked. Constant evaluation of PEF according to body height is necessary in chronic respiratory diseases, 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. Sometimes, it is useful for health professionals to have a guide as to what peak flow could be expected from each individual, if they didn't have asthma. Predictive Normal Values have been calculated for women and men of different ages and heights, and have been adapted (with agreement from the original Authors) for use with the new EU Scale / EN 23747 peak flow meters. 2008-07-04 · Therefore, variation in PEF is considered to be a measure of asthma severity 1, 2, and a diurnal variation in PEF of >15–20% is considered increased. There is, however, only limited evidence to support this cut-off point 1, 2, 8, 9. Measurements of lung function were used to determine asthma severity with <60%, 60-80%, and >80% predicted FEV1 and PEF values representing severe, moderate and mild asthma, respectively. The proportion of paired measurements in which differences in classification resulted from the use of FEV1 or PEF percentage predicted values was then calculated.
