wgm021 created the topic: Supplemental Oxygen
iv done the bob tait revision exercises and i came across one thing which i was unable to understand.
the supplemental oxygen level is 10000 to 25000 that is what i understood. The question based on pilots is correct when i select 10000 feet above.
but the samle question based on passengers states 14000 feet and above.
I didnt notice any seperate table for pilots and passengers for the levels and the type of oxygen required, please help.
Thank you for the help!
Another question that i came across while revising through the book was based on hypoxia and smokers
for example heavy smokers at 5000 feet they feel they are at 10000 feet and at sea level they feel they are at 8000 feet.
Is there any table i could refer to for the values on this sir?
I haven't found a good table, but here is an interesting graph. It plots the effect of hypoxia on smokers and non smokers at increasing altitudes. Note that as altitude increases, the difference between smokers and non smokers becomes less pronounced. At high altitudes, the advantage of being a non smoker becomes less significant. 0% represents a non smoker, 5% represents a moderate smoker and 10% represents a heavy smoker.
