Spirometry is important in evaluating patients with respiratory complaints and helpful in following the course of disease. The American Thoracic Society encourages office use of spirometry and has published guidelines and minimum standards to promote accurate and appropriate testing. Equipment designed to meet these standards is available for office use, and peak flowmeters are available for home use by selected patients. When performed correctly and interpreted in the context of other clinical data, spirometry may identify reductions in flow (obstruction) or volume (restriction). Characteristics of the flow-volume loop may suggest specific types of upper or large airways obstruction. Serial monitoring of forced expiratory volume in 1 second in chronic obstructive pulmonary disease and of peak expiratory flow rate in asthma may help guide medical therapy. When spirometry fails to detect or completely characterize impairment of lung function, more extensive testing in a pulmonary function laboratory is indicated.
肺量测定法对于评估有呼吸系统症状的患者很重要,并且有助于跟踪疾病进程。美国胸科学会鼓励在诊所使用肺量测定法,并已发布指南和最低标准以促进准确且恰当的检测。符合这些标准的设备可供诊所使用,峰值流量计可供选定的患者在家中使用。当正确执行并结合其他临床数据进行解读时,肺量测定法可能会识别出气流减少(阻塞)或肺容积减少(受限)。流量-容积环的特征可能提示上呼吸道或大气道阻塞的特定类型。对慢性阻塞性肺疾病患者的一秒用力呼气量以及哮喘患者的呼气峰值流速进行连续监测,可能有助于指导药物治疗。当肺量测定法未能检测到或完全表征肺功能损害时,则需要在肺功能实验室进行更全面的检测。
