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...
Background The variability of peak expiratory flow (PEF) is now commonly used in the diagnosis and management of asthma. It is essential for PEF meters to have a linear response in order to obtain an unbiased measurement of PEF variability. As the accuracy and linearity of portable PEF meters...

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)...
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 ...
摘要: We report two episodes of cardiorespiratory arrest immediately after measurement of peak expiratory flow in two young asthmatic subjects during an attack of asthma. Various mechanisms could be involved, particularly airway inflammation.关键词:...
is the measurement of how much the patient can blow out of their lungs in one breath. It is a crude measurement and not as accurate asSpirometry. However it is useful for patients to perform themselves, especially when they are having a flare up of their respiratory disease such as...
