The practicality of office spirometry has been established. Two basic parameters can be quickly and accurately measured in the physician's office or clinic: forced vital capacity (FVC) as a test of volume, indicative of restrictive lung disease, and forced expiratory volume in one second (FEV1) as a test of flow, indicative of obstructive lung disease. The ratio of FEV1 to FVC (FEV1/FVC%) is a valuable screening tool. Test results are compared with normal values, and abnormalities must be interpreted in the context of the individual patient's history and condition. Office spirometry provides a simple, noninvasive, inexpensive tool for assessing and managing respiratory disease.
办公室肺量计的实用性已得到证实。在医生办公室或诊所可以快速准确地测量两个基本参数：作为容积测试的用力肺活量（FVC），提示限制性肺病；作为流量测试的一秒用力呼气容积（FEV1），提示阻塞性肺病。FEV1与FVC的比值（FEV1/FVC%）是一种有价值的筛查工具。将测试结果与正常值进行比较，必须结合个体患者的病史和病情来解释异常情况。办公室肺量计为评估和管理呼吸系统疾病提供了一种简单、无创且廉价的工具。
