A procedure for using peak expiratory flow rate data to increase the predictability of asthma episodes

Abstract

An examination was conducted of the relationship between Peak Expiratory Flow Rate (PEFR) measurements obtained in the homes of two boys with asthma and the predictability of asthma episodes. An approach was developed for assessing the predictive utility of Pefr data. Results indicated approximately three-fold increases in the predictability of asthma episodes for the two experimental subjects. Potential applications of these results to the manage-ment of asthma are discussed.
