We have an Aerox system with cannulas and find it good. According to Aerox,
the system uses less oxygen than a mask would. We also have a Nonin Onyx
pulse oximeter, which is an essential accessory.

You're welcome to take a look at them if we get together at Cambridge some
time.

One of the things I hadn't anticipated was how much better I'd feel on
oxygen after longish flights even around FL100.
