interstitial pneumoniae
PCP
pulmonary edema
pulmonary hemorrhage
hypersensitivity pneumonitis (from methotrexate)
heroine, cocaine

37

normal A-a gradient

5 - 15 mmHg

38

what causes a high A-a gradient

pulmonary embolism
pulmonary edema
ARDS

compare to previous CXR

43

definition of chronic bronchitis

> 3 months of symptoms per year for at least 2 years
