Monitoring peak flow is most useful at key times. For example, if you’re recovering from an asthma attack, or your treatment plan has changed. You may be asked to keep a peak flow diary for a couple of weeks to help your GP confirm an asthma diagnosis. PEF variability is a measurement of airflow variability and should therefore be a close measurement of the inherent abnormality of asthma, but in practice it is difficult to estimate. Data was collected over 7 days and analysed over the last 5 days of recording to allow for learning effects 11 . The variability of PEF between periods at work and away from work has not been described in workers with work-exacerbated asthma (WEA).

The association between social class and asthma without allergic rhinitis. This indicates an association between negative asynchrony and variability of timing.

Asthma has two key defining features: • a history of respiratory symptoms such as wheeze, shortness of breath, chest tightness and cough that vary over time and in intensity, AND • variable expiratory airflow limitation. Asthma variability The variability of asthma was measured postrandomisation in two ways: as within-patient variability over time (the within-patient sd across the measurements taken for each patient during visits at 3, 6, 9, and 12 weeks), and as between-patient variability (the between-patient sd of all patients for the same measurements). Age and height were significantly associated with peak expiratory flows (PEF) in all subgroups.

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.
