ch 23 Flashcards
Main feature of restrictive pulmonary disorders?
Decreased lung expansion.
Four classifications of restrictive disorders?
Lung parenchyma, pleura, chest wall, neuromuscular function.
PFT finding in restrictive disease?
Decreased vital capacity, TLC, diffusion capacity.
ABG findings in restrictive disease?
Low PaO2, normal/low PaCO2, increased pH.
Severity of disease linked to?
Degree of lung volume decrease.
Interstitial lung disease feature?
Thickened alveolar walls with fibrosis.
Untreated interstitial lung disease leads to?
Irreversible fibrosis.
Diffuse interstitial lung disease feature?
Alveolar wall thickening.
Diffuse interstitial lung disease pathogenesis?
Injury, inflammation, fibrosis, destruction.
Honeycomb lung?
Cystic air spaces from fibrosis.
Clinical signs of diffuse interstitial lung disease?
Progressive dyspnea, dry cough, clubbing.
Diffuse interstitial lung disease diagnosis?
PFTs, chest X-ray, biopsy.
Diffuse interstitial lung disease treatment?
Avoid cause, corticosteroids, immunosuppressants.
Sarcoidosis etiology?
Unknown, idiopathic granulomatous disease.
Acute vs chronic sarcoidosis?
Acute self-resolves; chronic progressive.
Sarcoidosis pathogenesis?
Immune granuloma formation in lungs/lymph nodes.
Sarcoidosis clinical signs?
Erythema nodosum, eye issues, cough, dyspnea.
Sarcoidosis diagnosis?
Chest X-ray, biopsy: noncaseating granulomas.
Sarcoidosis treatment?
Corticosteroids, immunosuppressants if needed.
ARDS meaning?
Acute respiratory distress syndrome.
ARDS key features?
Alveolar-capillary damage, severe hypoxemia.
ARDS causes?
Sepsis, trauma, pneumonia, aspiration.
ARDS pathogenesis?
Inflammation, protein leakage, atelectasis.
ARDS early signs?
Rapid breathing, dyspnea, low PaO2.
