As a USA registered Rotorhead, I guess that you are quoting the FAA restriction of 18,000ft for cannula use. I suspect that Vertical Freedom is not operating under FAA regulations?
There are suppliers online who provide O2 Cannula systems for ops to 23,999ft. Google is quite clever at finding that sort of stuff
