O'mera relates that he uses O2 at altitude (above 10,000 feet), without getting into respiratory physiology once your blood has a certain Po2, adding oxygen has little effect and can be of some harm. A few liters per minute probably has little risk, although I think if it helps at low altitude you might need supplemental O2 all the time.
I seem to remember a report about someone breathing pure oxygen in an
attempt (apparently successful) to see fainter objects through a telescope at night.
Anyone else heard this?
I'm thinking that if it is true I might bring my aircraft's portable oxygen system to SPOC and use it while using the Grim to see if it makes any difference.
