  1. P(A-a)O2
    Alveolar arterial oxygen gradient
    • Really a measurement of pulmonary efficiency
    • It is the deference between the oxygen tension in the alveoli and the oxygen tension in the pulmonary capillary
    • If the lungs are working perfectly, there would be little difference between the alveolar oxygen tension and the tension in the arterial blood
  2. Normally humans have breathing room air have a P(A-a)O2 of...
    Between 25-75 mm Hg
  3. Pressure ventialation
    The practitioner sets an inspiratory pressure limit, rate, and inspiratory time
  4. The goal of prerssure ventilation!
    • Include the control and maintenance of inspiratory pressure, often ata level lower than that of volume ventilation modes
    • By controlling inspiratory pressures, often barotrauma may be reduced
  5. Hazards and complications of mechanical ventilation!
