For women, the equivalent figure is 85 L/min. Values are derived from Caucasian populations. Men. Height Age-Years. 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85. PEAK EXPIRATORY FLOW RATE - NORMAL VALUES For use with EU/EN13826 scale PEF meters only Adapted by Clement Clarke for use with EN13826 / EU scale peak flow meters from Nunn AJ Gregg I, Br Med J 1989:298;1068 -70 In me n, readings up to 100 L/min lower than predicted are within normal limits. For women, the equivalent figure is 85 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].

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. of reference values for lung function measurements in children.

2 However, many patients only present for review when their asthma is poorly controlled, and some measures of asthma control improve for many months after Lynn B. Gerald, Joan M. Mangan, in Clinical Asthma, 2008. PEAK EXPIRATORY FLOW (PEF) Peak expiratory flow is a simple measure of airflow obstruction that can be done by the patient themselves. Monitoring peak expiratory flow (PEF) can increase patient awareness of disease control, help patients detect significant changes in symptoms and make Green zone: Your PEF is 80%-100% of your personal best, meaning your asthma is under control. Take your medicines as usual. Yellow zone: Your PEF is 50% to 80% of your personal best.
RESULTS. Asthma Tracker 3 supports you in keeping your asthma diary up-to-date by making it easy to track your peak flow values, your asthma medication intake and
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.

For PEF measurement in asthmatics, inexpensive electronic home monitors can also be used which avoids the need for paper records and misleading 'false reporting'. References: 1.

It measures FEV1, FVC, PEF, FEV1/FVC, predicted values, expiratory curve, for screening COPD (Chronic Obstructive Pulmonary Disease) and asthma.

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.
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. Write down your peak flow number in your asthma diary every day.
