Q

What is FiO2?

A

Percentage of inspired gas that is Oxygen.
Room air is typically .21 (21%)
FiO2 x 6 should be close to your PAO2
FiO2 x 5 should be close to your PaO2

Q

What is alveolar volume? What is the “norm”?

A

Air present the alveoli available for actual gas exchange. Norm is ~350mL. Can affect this with Tidal Volume.
