Restrictive Lung Disease/ Muthiah Flashcards
Define restrictive lung disease
Disease in which the expansion of the lungs is impeded and the lungs cannot fill. Sort of counterintuitive since it seems like obstructive lung disease would prevent filling. It does not, it prevents emptying.
Restrictive disease that is parenchymal involves
functional lung tiissue injury. Parenchyma is just the bulk of an organ. The functional part.
Two types of parenchymal disease
Interstitial lung disease and resection of the lung tissue
Interstitial diseases generally involve what part of the parenchyma
alVEOLAR CONNECTIVE TISSUE
Asbestos, coal, silica cause granulomatous or non-granulomatous ILD
Non
What drugs can cause Non granulomatous ILD
Amiodarone, Bleomycin
The Hypoxia of ILD is due to
V/Q mismatch
Four lab characteristic of ILD
hypoxemia, hypercapnea, widened A-a gradient, exercise induced hypoxia
Most common symptom of ILD
Dyspnea….then cough and chest pain
Clubbing is a sign of
lung and heart disease…think thorax problems
Three stades of radiography
- ) Alveolar filling
- ) Interstitial
- ) Honeycombing
Example of a pleural disease
mesothelioma…leads to compression of the lung
Non-parenchymal causes of restrictive lung disease
Neuromuscular, chest wall problem, pleural problem
Bronchial Breath sounds are a sign of
Conolidation…Remember how it works…because there is so much fluid in the lungs, regular breath sounds from the trachea are conducted through the lungs
Aspiration pneumonia is usually caused by what?
Bacteria
