Pulmonary Flashcards
Risk factors for DVT
Stasis, endothelial injury, and hypercoagulability (Virchow’s triad)
Criteria for exudative effusion
Pleural/serum protein >0.5; pleural/serum LDH >0.6
Causes of exudative effusion
Think of leaky capillaries. Malignancy, TB, bacterial or viral infection, pulmonary emoblism (PE) with infarct, and pancreatitis
Causes of transudative effusion
Think of intact capillaries. CHF, liver or kidney disease, and protein-losing enteropathy
Normalizing PCO2 in a patient having an asthma exacerbation may indicate ______.
Fatigue and impending respiratory failure
Treatment for acute asthma exacerbations.
Beta2-agonists and corticosteroids.
Sarcoidosis
Dyspnea, lateral hilar lymphadenopathy on CXR, noncaseating granulomas, increase angiotensin converting enzyme, and hypercalcemia.
PFTs of obstructive pulmonary disease
Decreased FEV1/FVC
PFTs of restrictive pulmonary disease
Increased FEV1/FVC, decreased TLC
Honeycomb pattern on CXR. Treatment?
Diffuse interstitial fibrosis. Supportive care, antifibrotic agents may help.
Treatment for SVC syndrome
Radiation
Treatment for mild persistant asthma
Inhaled beta-agonists and inhaled corticosteroids
Treatment for COPD exacerbation
O2, bronhodilators, corticosteroids with taper, antibiotics, smoking cessation
Treatment for chronic COPD
Smoking cessation, home O2, beta-agonists, anticholinergics, systemic or inhaled corticosteroids, flu and pneumococcal vaccines
Acid-base disorder in PE
Respiratory alkalosis with hypoxia and hypocarbia
