The practicality of the office spirometer as an effective, inexpensive diagnostic device is well established. It can be used in a matter of seconds by minimally trained office personnel. Two basic parameters can be quickly and accurately measured: forced vital capacity (FVC), a test of volume indicative of restrictive lung disease, and forced expiratory volume in one second (FEV1), a test of flow rate indicative of obstructive lung disease. The FEV1/FVC ratio is a valuable screening measurement that indicates the likelihood of progressive deterioration of pulmonary function.
办公用肺活量计作为一种有效且廉价的诊断设备，其实用性已得到充分证实。经过最少培训的办公人员在短短几秒内就能使用它。两个基本参数可以快速且准确地测量出来：用力肺活量（FVC），这是一项反映限制性肺病的容积测试；以及一秒用力呼气量（FEV1），这是一项反映阻塞性肺病的流速测试。FEV1/FVC比值是一项有价值的筛查指标，可表明肺功能进行性恶化的可能性。
