PULM Flashcards
Risk factor for DVT
stasis, endothelial injury, hypercoagulability (Virchow!)
Criteria for exudative effusion
plerual/serum protein>0.5, pleural/serum LDH>0.6
causes of exudative effusion
leaky capillaries, malignancy, TB, bacterial or viral infection, PE w/ infarct, pancreatitis
Transudative effusion causes
intact capillaries = CHF, liver or kidney dz, protein losing enteropathy
normalizing PCO2 in pt having an asthma attack indicates what?
respiratory muscle fatigue and impending resp failure
Sarcoidosis sx and labs
dyspnea, lateral hilar adenopathy on CXR, noncaseating granulomas, increased ACE and hypercalcemia
PFT of obstructive dz
Decreased FEV/FVC
PFTof restrictive dz
Increased FEV/FVC, decreased TLC
Honeycomb pattern on CXR? Tx?
diffuse IPF, steroids may help but mainly give supportive care
Tx for SVC syndrome
radiation
Tx for mild persistent asthma
Inhaled B-Agonists and inhaled corticosteroids
Tx for COPD exacerbation
O2, bronchodilators, corticosteroids w taper, smoking cessation
Tx for chronic COPD
smoking cessation, home O2, beta agonists, anticholinergics, systemic inhaled corticosteroids, flu and pneumovax
Acid base disorder in PE
resp alkalosis w/ hypoxia and hypocarbia
Non small cell lung CA associated w/ hypercalcemia
squamous cell carcinoma
lung CA associated w SIADH
small cell lung CA
Tall caucasian man presents w acute shortness of breath. Dx?
Tx?
Spontaneous pneumothorax
Spontaneously regresses but supplmental O2 may help
Tx of tension pneumo
immediate needle thoracostomy
Characteristics favoring carcinoma in isolated pulmonary nodule
Age >45-50, lesions new or larger in comparison to old films, absence of calcifications or irregular calcifications, size >2cm, irregular margins
ARDS
Hypoxemia and pulmonary edema w/ normal pulmonary capillary wedge pressure
SEquelae of asbestos exposure
pulmonary fibrosis, pleural placques, bronchogenic carcinoma (mass in lung field), mesothelioma (pleural mass)
Increased risk of what infection w/ silicosis?
Mycobacterium TB
Causes of hypoxemia
R to L shunt, hypoventilation, low inspired O2 (altitude), tension, diffusion defect, V/Q mismatch
Classic CXR finding for pulmonary edema
cardiomegaly, prominent pulmonary vessels, Kerley B lines, bat wing appearance on CXR, perivacular/peribronchial cuffing
Westermark’s sign and Hampton’s hump
CXR findings suggestive of PE
