A common and mortal disease which can be diagnosed by simple observation and percussion of the chest. d. Bad. Really bad. "Pneumonia may well be called the friend of the aged.

Aspiration! Very common diagnosis Pneumonitis vs. pneumonia Pneumonitis Syndrome of inflammation Jello on the lung Focal infiltrate or bilateral opacities Patients recover quickly (hours) Community-Acquired Pneumonia 31

Aspiration! De-Escalation in HCAP Aspiration pneumonia True bacterial infection Usually focal infiltrate Occurs 48 hours after aspiration event If true pneumonitis, don t need antibiotics In general, can switch to a fluoroquinolone (levo or moxi) If fluoroquinolone allergy, can do Ceftriaxone + Azithromycin (or Augmentin + azithromycin at discharge) Community-Acquired Pneumonia Healthcare-associated Pneumonia 32
