Introduction[edit | edit source]
Restrictive lung diseases are a heterogeneous set of pulmonary disorders defined by restrictive patterns on spirometry. These disorders are characterized by a reduced distensibility of the lungs, compromising lung expansion, and, in turn, reduced lung volumes, particularly with reduced total lung capacity (TLC).[1]
Etiology[edit | edit source]
Its aetiology can be highly variable ranging from
- Intrinsic - with lung parenchymal involvement ie Interstitial Lung Disease: an umbrella term that encompasses a large number of disorders that are characterised by diffuse cellular infiltrates in a periacinar location. The spectrum of conditions included is broad, ranging from occasional self-limited inflammatory processes to severe debilitating pulmonary fibrosis[2].
- Extrinsic to the lung -
- obesity
- neuromuscular disorders
- chest wall deformities
- scoliosis: can lead to extrinsic restrictive lung disease from the diminution of lung volume under the convex rib hump and on the concave side, where the ribs impinge on the lung 4
- excessive kyphosis
- kyphoscoliosis
Those with a restrictive lung disease pattern can often have decreased lung volumes, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function tests often demonstrate a decrease in the forced vital capacity (FVC)[3].
