Selection of peak flowmeters in ambulatory asthma patients: a review of the literature.
The National Asthma Education and Prevention Program recently published updated guidelines that stress the importance of peak flow monitoring for patients with moderate-to-severe persistent asthma. In this specific patient population, a peak flowmeter provides a simple, quantitative, objective measurement of large airway function. The purpose of this article is to describe indications for peak flow monitoring in asthmatic patients, review technical requirements for peak flowmeters as described by the National Heart, Lung, and Blood Institute, and evaluate the literature on commercially available peak flow devices to aid the health professional in selecting an appropriate meter for the patient with moderate-to-severe persistent asthma.
