Use of the peak flow meter in office practice.
The peak expiratory flow rate (PEFR) may be measured in the office or at home with an inexpensive, hand-held meter. Measurement of the PEFR provides a rapid, objective means of diagnosing and monitoring asthma. Use of the peak flow meter permits early detection of deteriorating function, allowing timely institution of additional therapeutic measures and preventing the need for hospital admission. During an acute attack of asthma, the PEFR aids in determining whether admission is necessary.
