Description

The measurement and analysis of the standard range of peak expiratory flow (PEF) in normal, healthy Japanese is necessary at any cost to facilitate bringing the Japanese Guidelines for Bronchial Asthma smoothly into effect. In a study as part of The Bronchial Asthma Group of the Comprehensive Research Project (Terumasa Miyamoto, Chairman of the planning and Evaluation Committee) under the auspices of the Ministry of Health and Welfare, we measured PEF in 2,785 healthy Japanese volunteers (1,407 males aged 15-84 years and 1,738 females aged 15-80 years) who had no history of smoking, respiratory and/or thoracic diseases, or wheezing with four different peak flow meters (e.g., mini-Wright, Assess, Personal-Best and Vitalograph). As a result of comparing PEF measured by the four meters in the same subjects over a short interval of time, we noted significant differences on analysis of variance. Accordingly, the equation for prediction should account for variables in gender and the type of peak flow meter used. A comparison of cubic equations for prediction suggests that the PEF of both Japanese men and women is similar to that of the British but is different from that of the Chinese.
