PFT is a valuable tool for evaluating the patient with respiratory complaints and for screening the high-risk population. It is no longer only a hospital-based test, but, with current technology, is an efficient, practical procedure that can be performed in an office at minimal cost to the patient. In addition, serial spirometry can be used to identify high-risk populations and gauge response to bronchodilator therapy. Spirometry should be performed routinely in all smokers older than 40.
肺功能测试（PFT）是评估有呼吸道症状患者和筛查高危人群的一项重要工具。它不再仅仅是一项基于医院的检查，而是借助当前技术，成为一种高效、实用的程序，可在门诊以患者花费极少的成本进行。此外，系列肺量测定法可用于识别高危人群并评估对支气管扩张剂治疗的反应。对于所有40岁以上的吸烟者，应常规进行肺量测定。
