The accuracy, reproducibility, and variability of seven commercially available peak flowmeters were assessed using the pulmonary waveform generator as recommended by the American Thoracic Society. The standard models were tested for peak flows of 100, 200, 320, 500, and 700 L/min. The low-range models were tested for peak flows of 80, 150, 200, 250, and 320 L/min. Most of the units provided highly repeatable estimates of peak flow. However, the accuracy of several devices (Assess [Healthscan Products, Cedar Grove, NJ] and Mini-Wright [Clement Clarke International, Harlow, Essex, UK] low-range models, and the Ferraris [Ferraris Medical, Holland, NY] and Mini-Wright standard-range models) did not meet the National Asthma Education Program (NAEP) recommendations. The device with the best performance in terms of accuracy, variability, and reproducibility, and the only one in which all units tested met the NAEP recommendations, was the Astech (Center Laboratories, Port Washington, NY) full-range model.
按照美国胸科学会的建议，使用肺波形发生器对七种市售峰值流量计的准确性、可重复性和变异性进行了评估。对标准型号进行了100、200、320、500和700升/分钟峰值流量的测试。对低量程型号进行了80、150、200、250和320升/分钟峰值流量的测试。大多数设备提供了高度可重复的峰值流量估计值。然而，几种设备（Assess[Healthscan Products，新泽西州雪松格罗夫]和Mini-Wright[Clement Clarke International，英国埃塞克斯郡哈洛]低量程型号，以及Ferraris[Ferraris Medical，纽约州荷兰]和Mini-Wright标准量程型号）的准确性未达到国家哮喘教育计划（NAEP）的建议。在准确性、变异性和可重复性方面表现最佳的设备，也是所有测试单元均符合NAEP建议的唯一设备，是Astech（Center Laboratories，纽约州华盛顿港）全量程型号。
