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
Normally humans have breathing room air have a P(A-a)O2 of...
Between 25-75 mm Hg
The practitioner sets an inspiratory pressure limit, rate, and inspiratory time
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
Hazards and complications of mechanical ventilation!
