- - - - often dry c. + lots of CP + low sats
- - - - air cant reach areas that are infected/ consolidated
      - shunt: blood going to areas of consolidation but not experiencing oxygenation
    - - increase RR
      - improve ventilation of adequately perfused lung units
- - - - vascular engorgement
        
        influx of neurophils
        
        exudation of protein rich fluid into alveolar spaces
        
        consolidation of lung parenchyma
  - - - neutrophils influx only initially
        
        mononuclear cells
- - - - often bacterial
      - induces 1° neutrophilic exudate in alveoli, bronchioles + bronchi
    - - fungi, parasites + intracellular bacteria
