Peak expiratory flow (PEF) monitoring has long been a mainstay of asthma management, but controversy surrounds its efficacy in the pediatric population, and little published research exists on the subject. PEF is both effort and technique dependent and is not suitable for use in children under the age of 5 or with developmental disabilities. However, PEF is useful for monitoring airway changes if used properly, especially in that segment of the population labeled as "poor perceivers" of worsening symptoms. The authors review existing literature on the subject, including the newly revised National Heart, Lung, and Blood Institute (National Heart, Lung, and Blood Institute, National Institutes of Health, U.S. Department of Health and Human Services. (2007). Expert panel report 3: Guidelines for the diagnosis and management of asthma-full report 2007.

呼气峰流速（PEF）监测长期以来一直是哮喘管理的主要手段，但在儿科人群中的疗效存在争议，关于这个主题的研究很少。PEF 既依赖于努力程度，也依赖于技术，不适合 5 岁以下或有发育障碍的儿童使用。然而，如果正确使用，PEF 可用于监测气道变化，特别是在那些被标记为“对症状恶化感知能力差”的人群中。作者回顾了该主题的现有文献，包括新修订的美国国立心肺血液研究所（美国国立卫生研究院，美国卫生与公众服务部。（2007）。专家组报告 3：哮喘诊断和管理指南-全文 2007。从 http://www.nhlbi.nih.gov/guidelines/asthma/asthgdln.htm 检索，2008 年 6 月 17 日）循证指南。
