7. Oxygen was first used as a
remedy for illness in 1783 in
France by Chaussier. In
December of 1907, it was
used in surgery on a woman
who had tremendous internal
damage. It was administered
directly into the abdomen
and marked recovery was
noted.

16. PaO2 / FiO2 Ratio or "P/F” Ratio
 Another much friendlier method
( because it doesn't use the alveolar gas
equation) used to predict shunt.
 Just like the name says, PaO2 is divided by
FiO2
 Normal is 286; lower indicates a shunt.

33. Non-Rebreather masks achieve close to
100% oxygen by minimizing room air
entrainment and by attaching a
reservoir bag filled with 100% oxygen.
The reservoir bag has a flap valve to
block exhaled gas from entering.
Exhaled gas is directed out the side
ports with flap valves to block air
entrainment on inspiration.
