Restrictive Lung Diseases Flashcards
1
Q
What characterises Restrictive Lung Disease?
A
- reduction in lung volume
- difficulty in taking air in
- stiffness inside the lung tissue
2
Q
What can cause a restrictive pattern?
A
- interstitial lung disease (ILD)
- Scoliolisis
- neuromuscular disease
3
Q
ILD meaning
A
- interstitial lung disease
- restriction in normal lung function
- impaired gas exchange
- inflammation / fibrosis
4
Q
Idiopathic Pulmonary Fibrosis?
A
- Fibrosis / honeycombing
- overproduction of fibroblasts
- loss of elasticity
- bi-basal end-inspiratory crackles
- Normal/increased FEV1/FVC ratio
5
Q
Explain DLCO
A
- Diffusion capacity of carbon monoxide
- measures gas diffusion across alveolar barrier
- decreases for emphysems, ILDs and aneamia
6
Q
Intrinsic causes of Restrictive LD
A
- IPF
- Granulomas
7
Q
Extrinsic cause of restrictive LD
A
- Obesity
- scoliosis
- diaphragm paralysis
8
Q
Hypoventilation leads to»»>
A
impared alevolar ventilation
9
Q
Type 1 respiratory failure
A
- decreased o2
- decreased co2
10
Q
Type 2 respiratory failure
A
- decreased o2
- increased co2
11
Q
Early stage of ILD
A
- Alveolitis
12
Q
Late stage of ILD
A
- Fibrosis
13
Q
Hypersensitivity penumonitis (HP)
A
- Chronic inflammatory disease
- type III or IV
14
Q
Sarcoidosis
A
- multisystem granulomatous disorer
- Type IV hypersensitivity
- bilateral hilar lymphadenopathy
15
Q
Pneuoconiosis caused by
A
- absestosis
- silicosis
- bird fanciers lung
- coal workers lung etc
16
Q
Caplans sydrome?
A
Rheumatoid pneumoconiosis
17
Q
Coal workers lung effects which region of lung?
A
Upper lobes
no hilar involvment
18
Q
Silicosis effects which region of lung
A
- upper lobes
19
Q
TB likelihood is increased with what?
A
- sacrodisis
20
Q
Asbestos effects which regions of lungs
A
- bottom
