Asthma is characterized by a reversible bronchial obstruction. Some patients may present a restrictive lung function pattern. Most often, this is due to extrapulmonary causes such as obesity, scoliosis, etc. As in chronic obstructive pulmonary disease (COPD), a "pseudorestriction," a lowered forced vital capacity (FVC) due to dynamic hyperinflation with air trapping, may be seen. This article presents two patients suffering from asthma who had an considerable impairment of total lung capacity (TLC) and FVC when their asthma was poorly controlled, showing a complete reversibility of restriction when treated properly for the asthma.
哮喘的特征是可逆性支气管阻塞。一些患者可能呈现限制性肺功能模式。最常见的情况是，这是由肺外原因引起的，如肥胖、脊柱侧弯等。与慢性阻塞性肺疾病（COPD）一样，可能会出现“假性限制”，即由于气体潴留导致的动态肺过度充气而使用力肺活量（FVC）降低。本文介绍了两名哮喘患者，他们在哮喘控制不佳时总肺容量（TLC）和FVC有相当程度的损害，而在对哮喘进行适当治疗后，限制性表现完全可逆。
