In restrictive lung disease, the FEV1/FVC ratio and compliance of the lung are decreasing.

Restrictive lung diseases, such as pulmonary fibrosis or severe asthma, are characterized by a decrease in the lung's ability to expand due to factors like stiffening of the lung tissue or a reduction in the volume of the thoracic cavity. As a result, the forced expiratory volume in one second (FEV1) is reduced in relation to the forced vital capacity (FVC), leading to a decreased FEV1/FVC ratio. Additionally, the compliance of the lung, which is a measure of the lung's ability to expand and contract, is also decreased in these conditions because the lung tissue becomes less elastic.
