Bacterial pneumonia is bacterial infection of the lung (S. pneumoniae, H. influenzae, S. aureus, Klebsiella, Moraxella, atypical - Mycoplasma/Chlamydia/Legionella), presenting with fever, productive cough, pleuritic pain, dyspnea, and focal consolidation. Treatment: empiric antibiotics (amoxicillin-clavulanate/macrolide/respiratory fluoroquinolone) by setting (CAP/HAP/VAP); oxygen; fluids; treat complications (effusion/empyema/ARDS); cultures; de-escalate; vaccination for prevention (pneumococcal/influenza).

Bacteria aspirate/infect lung parenchyma, causing consolidation and impaired gas exchange.

Treatment

Empiric/directed antibiotics; oxygen/fluids; drain empyema; vaccination prevention

Preventive Measures
