Restrictive lung disease

Last revised by David Luong on 28 Jul 2021

Restrictive lung disease (or a restrictive ventilatory defect) is a physiological spirometric term given to a heterogeneous group of conditions that result in restricted lung expansion. It is not equal to but can be related to pulmonary fibrosis as extrapulmonary e.g. thoracic wall conditions can result in a restrictive lung disease pattern.  

Its etiology can be highly variable ranging from:

Patients with a restrictive lung disease pattern can often have decreased lung volumes, increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function tests often demonstrate a decrease in the forced vital capacity (FVC).
