摘要

肺活量测定法是最常见的肺功能或呼吸测试。这是最容易获得和最有用的肺功能测试之一。它测量在用力完全呼气过程中特定时间点呼出的空气量,在此之前是最大的吸气量。报告中最重要的变量包括总呼气量,称为用力肺活量(FVC),第一秒呼气量,称为用力呼气量(FEV1),以及它们的比值(FEV1/FVC)。该测试可以在诊断和治疗许多肺部疾病方面发挥重要作用。它可以帮助区分具有相似症状的疾病,并确定病情是否为阻塞性和/或限制性。

Spirometry - The Pulmonary Function Test
Spirometry is the most common type of pulmonary function or breathing test. It is one of the most readily available and useful tests for pulmonary function. It measures the volume of air exhaled at specific time points during complete exhalation by force, which is preceded by a maximal inhalation. The most important variables reported include total exhaled volume, known as the forced vital capacity (FVC), the volume exhaled in the first second, known as the forced expiratory volume in one second (FEV1), and their ratio (FEV1/FVC).The test can play an important role in diagnosing and managing many lung problems. It can help distinguish between diseases with similar symptoms and determine whether the condition is obstructive and/or restrictive.
