... and then there's they guy from the thread a month or two ago that said
that since he was barely affected (aside from a bit of shortness of
breath) when doing
manual labor in an unpressurized plane climbing to 25,000 ft that all
the hype about
being "noticably affected" below 15,000 was bull****.

Again I call bull****.

Unless you are moderately active in excercise and live in the rockies at 5000
feet or higher, or are a particularly unusual person, you WILL be
impaired at 10k for
any time longer than a few minutes. Hypoxia is insideous.

I live in the Rockies higher than 5K (well, actually, Denver is in the
plains, but we're still that high). And I still get tired in the
mountains on my way skiing, and exhausted when I get home. I've been
trying to figure out a way to carry my O2 bottle while skiing, but
I'm sure the ski area lawyers wouldn't allow it.

A little over-generalized, but it is something folks need to take seriously.

What I've found is every person is different. You can't say that one person
who lives at sea level will be effected one way and someone else who lives
in the mountains will be different. I've seen cases that I would agree, and
I've seen the exact opposite.

Everyone needs to be aware of their own personal limitations and respect the
altitude and lack of oxygen.

But there's impaired and IMPAIRED.

I've lived at sea level pretty much all my life - where I live now is
about 90ft MSL, where I last lived was 25ft MSL.

However, I can happily go skiing all day long in Utah, doing vigorous
exercise between 9000 and 12000 ft all day long. I am not unusual (well,
I might be weird but physically I'm not unusual).

My first post on your group.
I've read this entire thread and am suprised that no one has mentioned
using
an O2 system from a home healthcare type source.
It's the same 02, the same bottles. the same delivery method, just
maybe a
whole lot cheaper than buying something that says "airplane" on it.
I've been quoted about $200 for a 6# tank and regulator, with cannulas.
The
Regualtor is metered by volume per minute. ie 2 liters per minute.
Would this work, why? why not?
About me,
1972 Piper Arrow II only capable of flights to around 12,000 MSL ( for
all
intents and purposes)
Dallas, TX.
Would like to have it cause I don't want to die.

IN ground school I was taught that medical O2 has water in it which can
freeze in the lines at high altitudes and low pressures. I've never
used O2 so have no firsthand experience.

There may be a difference in the water specification between medical and
aviator's oxygen, but there is no practical difference. It all comes from the
same oxygen plant. There's an article on the subject at avweb.

I've never tried it, but I've been told that medical oxygen supply places want
to see your prescription, or no sale.

I have had the same experience, although my ability to tolerate high
altitude exercise has declined with age (I'm 61).
I have also flown frequently between 9500 and 12500 with no apparent
ill effects. However, my wife complains of
headaches if I take her above 10,000 or so.

It works just fine. I have a medical cylinder and the local medical gas supply house happily refills it. The
regulator is in liter/min. I asked one of the Oxygen system vendors at Oshkosh about that, and he said a
good rule of thumb is one liter/minute per person. I also bought a pulse oximeter, so that eliminates the
guess work.

Pilots in WWI routinely flew patrols at altitudes up to 20,000' without oxygen.
Basically, being physically able to perform at 6,000 meters was part of the
criteria for being an airman. If you couldn't hack it, you washed out (or died).

Drink is the curse of the land. It makes you quarrel with your neighbor.
It makes you shoot at your landlord. And it makes you miss him.

Thanks for all the great responses!

Another question that hit me (without getting into the whole aviation 02
vs
medical 02 vs welding 02 debate)

What is the average cost for your refills with aviation 02?

By the way, all the vendors will top off your bottles for free at Oshkosh
(and probably the other major shows). Handy thing to remember.
