Aviation Oxygen (merged)

Oxygen generator/concentrator thread

A few people seem to use them and they do work. Well, the ones designed for aviation do; most of the stuff on the market is for people with lung/heart conditions who are on oxygen all or most of the time.

I used to know one SR22 owner with the Sequal one, who I believe had a special power connector installed in the plane (the unit draws a lot of current) but he has dropped down to the UL scene and his email has gone dead. There is some funny stuff in the above thread; I believe a number of the Ebay ones were “acquired” from a US military hospital somewhere around Italy

I was reading elsewhere on oxygen concentrators, where the machine removes the nitrogen from the air.

This would save the hassle etc of having oxgen on board ?

This is the regulator on the cylinder in work. What would I need to buy if I wanted to fill an aviation oxygen cylinder from it?

I am not 100% sure but it looks just like the one I have at home. Also you are not far from the UK… so the BOC fitting is likely.

Yep it’s a BOC cylinder. Should have included that detail! Thanks for the contact.

Question for those of you flying with the O2D2 EDS system from Mountain High. At FL150 (or there about) do you find that D10 setting with standard cannulas (non flare tip) is sufficient to deliver 90+ pulse oximeter readings?

I have found that F2/F3 provides better levels for me but realise this consumes substantially more oxygen….

D10 at 160 yes
D5 at 180 (didn’t test D10) too

I find the first (the standard) setting is fine to FL200, for ~95%, but it does require very deliberate breathing anywhere near that level. The other settings are obviously better.

The oxisave canals I’m familiar with are manufacturer limited to FL180. After that it’s a mask.

AIUI the 18k cannula limitation is driven by the AFMS for fitted oxygen systems. For portable systems, there is no such limitation.
