最大呼气流速——容量曲线(简称MEFV)测定对早期诊断小气道疾患的价值已引起国内外学者的重视,但其正常值因受各种因素的影响,至今仍无一个较一致的正常范围作为临床诊断的标准。我院应用上海573的LR—80型流速——容量记录仪测定健康无吸烟史者146例。现将结果报道于后。
The value of maximal expiratory flow rate-volume curve (MEFV) measurement for early diagnosis of small airway diseases has attracted the attention of scholars at home and abroad, but its normal value is still not a more consistent normal range due to various factors As a clinical diagnostic criteria. Shanghai Institute of Applied 573 LR-80-flow velocity-volume logger determination of healthy non-smoking history of 146 cases. The results are reported later.
