      1. Perfusion (side) | The ability of blood to pass through the lungs and pick up oxygen.
      2. Altitude sickness | A condition in which a low amount of oxygen in the air (which exists at high altitudes) causes the blood vessels that supply the lungs with blood to undergo vasoconstriction, which reduces the amount of oxygen that can be picked up and delivered to the tissues.
      3. Hypoxia (hypoxic) | Low amount of oxygen in the blood.
      4. Ventilation (side) | For proper gas exchange in the lungs, you have to have sufficient blood flow (perfusion) and you have to have sufficient oxygen in the lungs (ventilation). An imbalance of either or both can lead to hypoxia.
      5. ARDS | Acute Respiratory Distress Syndrome
      6. PEEP | Positive End Expiratory Pressure |
      7. Pulmonary embolism | A blood clot in the blood vessels that supply the lungs, which interferes with normal lung perfusion.
      8. Blood clots (thrombus) | A collection of platelets and fibrin that occurs inside of a blood vessel. |
      9. Low molecular wt heparin (LMWH) | A drug that prevents the formation of blood clots.
      10. Cytokine storm | This video is a nice introduction to the immune system.
