Restrictive Lung Diseases Flashcards
What characterises Restrictive Lung Disease?
- reduction in lung volume
- difficulty in taking air in
- stiffness inside the lung tissue
What can cause a restrictive pattern?
- interstitial lung disease (ILD)
- Scoliolisis
- neuromuscular disease
ILD meaning
- interstitial lung disease
- restriction in normal lung function
- impaired gas exchange
- inflammation / fibrosis
Idiopathic Pulmonary Fibrosis?
- Fibrosis / honeycombing
- overproduction of fibroblasts
- loss of elasticity
- bi-basal end-inspiratory crackles
- Normal/increased FEV1/FVC ratio
Explain DLCO
- Diffusion capacity of carbon monoxide
- measures gas diffusion across alveolar barrier
- decreases for emphysems, ILDs and aneamia
Intrinsic causes of Restrictive LD
- IPF
- Granulomas
Extrinsic cause of restrictive LD
- Obesity
- scoliosis
- diaphragm paralysis
Hypoventilation leads to»»>
impared alevolar ventilation
Type 1 respiratory failure
- decreased o2
- decreased co2
Type 2 respiratory failure
- decreased o2
- increased co2
Early stage of ILD
- Alveolitis
Late stage of ILD
- Fibrosis
Hypersensitivity penumonitis (HP)
- Chronic inflammatory disease
- type III or IV
Sarcoidosis
- multisystem granulomatous disorer
- Type IV hypersensitivity
- bilateral hilar lymphadenopathy
Pneuoconiosis caused by
- absestosis
- silicosis
- bird fanciers lung
- coal workers lung etc
Caplans sydrome?
Rheumatoid pneumoconiosis
Coal workers lung effects which region of lung?
Upper lobes
no hilar involvment
Silicosis effects which region of lung
- upper lobes
TB likelihood is increased with what?
- sacrodisis
Asbestos effects which regions of lungs
- bottom
