  • Elevated diaphragm
  • Decreased lung volumes (functional residual capacity)
    • Increased ventilation–perfusion mismatch
    • Increased alveolar–arterial oxygen gradient
  • Decreased lung compliance and increased resistance
    • Increased pleural pressures
    • Increased airway pressures
  • Uneven gas distribution
  • Cephalad displacement of carina
    • Endobronchial intubation
