By measuring peak flow we can check how well your asthma is controlled.” Gain consent to proceed with PEFR measurement. Position the patient so that they are sitting comfortably. Ask the patient if they have any pain or shortness of breath before performing PEFR measurement. After expected increases through childhood and adolescence, PEFR decreases with age from 30-40 years onwards (see Figure 1). Figure 1 Asthma is the most common condition that affects peak flow.

Your Asthma Action Plan may tell you to take your peak flow reading more often and to adjust your medicines. Use only one meter.

Peak Expiratory Flow Rate [PEFR] Peak expiratory flow rate is the maximal rate of air flow which is a subject can achieve by a forced expiration.

Occupational asthma is the leading occupational respiratory disease. Epidemiological studies of occupational asthma have made use of the serial peak expiratory flow rate (PEFR) monitoring as a tool to identify cases, describe prevalence and to compare the mean diurnal variation (DV) in PEFR with an …

Peak Expiratory Flow (PEF), also called Peak Expiratory Flow Rate (PEFR) is a may determine lung functionality, severity of asthma symptoms, and treatment

Although PEFR may aid emergency physicians during their evaluation and treatment of an adult patient with an acute exacerbation of asthma, the evidence does not support requiring PEFR monitoring for all adult patients. PEFR monitoring is a simple and cost‐effective means of determining the degree of airways obstruction. PEFR is a tool for monitoring patients with asthma, but it should not be used for the diagnosis of asthma. Patients with moderate or severe asthma should be instructed in the use of PEFR and have a peak flow meter accessible for self 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 1.
