    • redistribution
    • core
    • peripheral
    • cold ambient temperature, prolonged exposure of a large wound, use of large amounts of unwarmed IV fluids, high flows of unhumidified gases.

    PaO2 of <60% with O2 content >60%
  13. Pathophysiology behind atelectasis -->
    hypoventilation, V/Q mismatch, intrapulmonary and extrapulmonary shunting
  14. During a general anesthetic, how should the eyes be protected for a patient who has recently undergone LASIK surgery?
