Apeak flow meterorpeak flow meter(PFM) is a device used to measure the volume of air a person breathes out as a measurement of pulmonary function. A peak flow meter is a device used in the diagnosis and treatment ofrespiratorydisorders such as asthma. This device measures the maximum amount...
Each year around 2000 people die from asthma in England and Wales and two-thirds of these deaths are preventable. The economic costs of asthma are huge.doi:10.1007/978-1-4899-3059-0J. G. AyresP. J. TurpinSpringer USAyres JG, Turpin PJ: Peak flow measurement. An illustrated guide. ...

A peak flow meter is not an appropriate tool for diagnosing asthma. Patients take three peak flow meter measurements, and the best measurement is recorded on the peak flow meter chart. The measurements can be plotted over time on graph paper along with anecdotal information about a patient’s...

Why and when we measure peak expiratory flow? As peak flow measures bronchial diameter, people at risk of rapid bronchoconstriction will benefit from it. These are mostly patients with asthma. While it can never replace spirometry, the standard lung examination, but regular peak flow measurements ...
Asthma is characterized in part by small airways dysfunction. Peak expiratory flow (PEF) measurement has been suggested by all international guidelines as an important tool in asthma management. The correlation between PEF and FEV1but not with forced expired flow at 50% of vital capacity (FEF50)...
Inhaler device technique is a common cause of treatment failure in patients with asthma and chronic obstructive pulmonary disease. Dry powder inhaler (DPI) requires optimal peak inspiratory flow rate (PIFR) for drug delivery. Low PIFR generation is common in the elderly. Patient lung function and...
Peak expiratory flow(PEF) is the maximal flow that a person can exhale during a short maximal expiratory effort after complete inspiration. In patients with asthma, PEF correlates with FEV1, but it should not be used as its substitute. Peak expiratory flow is a measurement that is easy to do...
It is most commonly measured by a portable flow gauge device (peak flow meter [PFM]) but may also be obtained by a transducer that converts flow to electric output during spirometry (pneumotachometer). [3] The most frequent use of PEFR measurement is in home monitoring of asthma, where ...
