Having acquired data from an individual, the first step is to determine whether any of the test After the starting point the curve rapidly mounts to a peak: Peak (Expiratory) Flow. After the PEF the curve descends (=the flow decreases) as more air is expired. A normal, non-pathological F/V loop will descend in a straight or a convex line from top (PEF) to bottom (FVC). 2003-11-01 An important tool for the diagnosis and subsequent treatment of asthma is the PEF meter. PEF is the highest expiratory flow obtained during a forced expiration starting immediately after a deep inspiration from total lung capacity.

Occupational asthma was confirmed with a positive Oasys score >2.5 and a mean rest-work PEF >16 l/min from serial 2-hourly PEF measurements. The Oasys PEF plotter calculated differences between rest and workdays for mean PEF, diurnal variation and the scores were used to confirm an occupational effect (Oasys, area between curve and time point). 2020-02-13 · Peak expiratory flow rate (PEFR) is the maximum flow rate generated during a forceful exhalation, starting from full lung inflation. Peak flow rate primarily reflects large airway flow and depends on the voluntary effort and muscular strength of the patient. Mean changes in PEF across morning/day shifts were compared between workers with occupational asthma, confirmed using specific challenge testing, and non-working asthmatics. Individuals were divided into a development set, used to identify the optimum cross-shift change for diagnosing occupational asthma, and an evaluation set, used to test the sensitivity and specificity of this value.

However, a change of more that 15% indicates poor asthma control. 3 The measurement is also called the peak expiratory flow rate (PEFR) or the peak expiratory flow (PEF). Peak flow measurement is mostly done by people who have asthma. Peak flow measurement can show the amount and rate of air that can be forcefully breathed out of the lungs. The measurement should be started after a full lung inhalation. peak ex·pi·ra·to·ry flow (PEF) (pēk ek-spīră-tōr-ē flō) Maximum flow at the outset of forced expiration, which is reduced in proportion to the severity of airway obstruction, as in asthma.
