When confronted with a case of dyspnoea, three questions must be asked: is the dyspnoea due to a pulmonary organic disease? How severe is it? What is its nature or its origin? In the majority of cases these questions are answered by elementary lung function tests (spirometry and measurement of the residual volume), but for these answers to be valid it must be borne in mind that respiratory function test (RFT) is primarily a physical exercise: no measurement is valid unless the operator is fully involved and the subject explored participates to the best of his possibilities. RFT also is a mental exercise: the data obtained can be well understood only if the operator is conversant with the data described in this article. RFT has multiple applications, and yet this examination is notoriously underestimated and underused by the medical profession. Good practice is its best publicity.
面对呼吸困难的病例时，必须提出三个问题：呼吸困难是否由肺部器质性疾病引起？其严重程度如何？其性质或起源是什么？在大多数情况下，这些问题可通过基本的肺功能测试（肺活量测定和残气量测量）来回答，但要使这些答案有效，必须记住呼吸功能测试（RFT）主要是一种体力活动：除非操作人员全身心投入且接受检查的受试者尽最大可能配合，否则任何测量都是无效的。RFT也是一种脑力活动：只有当操作人员熟悉本文所述的数据时，才能很好地理解所获得的数据。RFT有多种应用，然而这项检查却一直被医学界严重低估和未充分利用。良好的实践是它最好的宣传。
