Supplemental O2 and children

Good for you. That is what it is all about, and it happens with the little
things in life.

I get a tight feeling between my eyes, same as having two
beers when at 25,000 feet without O2. This was same
reaction every time I've been in the chamber at OKC. A
person in good health can do OK at 15,000 for some time if
they are not required to think or do any tasks. Hypoxia is
a cheap drunk for me, but I am peaceful and polite.

The pilot must use O2 any time above 14,000 while it must
only be available for passengers at 15,000. Personally, I
use O2 at and above 10,000 if it is available. At night,
you can notice the difference as low as 5,000 feet.

If you start using O2, leave it on until you're back to a
lower altitude, blood saturation drops very quickly and a
quick shot will bring you UP but it doesn't last unless you
stay on the O2. You can set the O2 regulator to deliver the
required amount of oxygen to maintain the blood at close to
100%, but you must keep it at 95% to stay fully alert. If
you have the available supply, everybody should use O2 at
10-12,000 or above.

The rules for Part 91 are not as tight as Part 135. Make
sure that you explain how to use and why to your passengers
and do a check to be sure everybody is getting their O2
[hoses get kinked, masks not on or sealed, tank empty.]
BTW, an O2 tank should never be run below 100 PSI, keeps all
the gas inside dry and rust free.

I would have to disagree... The problem with bribery is that sometimes the
individual won't stay bribed... Fear is a significantly better motivator...

Obviously, above a certain altitude, judgement would be impaired,
however what altitude and exposure time is required for permanent
damage to occur?

The answer appears to be "It depends"... Acclimation can make a big
difference. People climb Everest without O2, but they spend weeks
acclimating and I've read different opinions brain damage on them.

Smoking, the altititude you live at, etc. make a big difference when you
fly. Some examples:

http://www.smartcockpit.com/operatio...ompression.pdf
The effects of hypoxia may vary from one person to the next,

depending on the person's health, state of fatigue, state of

physical fitness and how much activity an individual must

perform. (Pilots and flight attendants require more oxygen

during an emergency than typical, healthy, seated passengers.)

Because the eyes and the brain have a high metabolism and

cannot store oxygen, they are most sensitive to oxygen

depletion; the first measurable decline in the body's functioning

occurs in sight, with some loss of night vision at altitudes as

low as 5,000 feet.22 After several hours at 10,000 feet, many

people experience a "measurable deterioration" of their mental

abilities and physical dexterity. At 18,000 feet, the mental

deterioration may be followed by unconsciousness; the TUC

at that altitude is about 15 minutes. At 25,000 feet, the TUC

may be as little as three minutes, and in some situations,

exposure to cabin altitudes of more than 25,000 feet without

supplemental oxygen for more than two minutes might result

in permanent brain damage. At higher altitudes, the TUC

decreases rapidly; at 40,000 feet, for example, the TUC may

be 15 seconds or less.

Other physical effects of decompression include the painful

expansion of gases in body cavities - the stomach and

intestines, the joints, diseased areas beneath the teeth and inside

decayed teeth - and pain in the middle ears and the sinuses

as the body adjusts to the pressure change.19 If the

decompression is slow, one of the early symptoms of hypoxia

is a blue tinge on the lips and under the fingernails; the color

change is a result of the reduction of oxygen in the hemoglobin

of red blood cells.23

If your kids are not normally inclined to behave themselves, you've screwed
up.

Granted, lots of parents are screw-ups.
