Here we have my proposed, self contained, no bottle, Oxygen system.
Its an Inogen One G2 HF (high flow). I've done all the research I can and I hope this is going to work. The down side is its weight, 7.5 lbs with the bigger battery and the 1lb 12v adaptor.
Size is 9.5" tall, 3.9" wide and 10.7" deep. A version of this unit is certified to 18,000' with a cannula. Thats the maximum height with cannula anyway. I suspect from a lot of research that the certified one is a rebranded exact same version as this one. I'm 90% sure.
I am arranging a flight where I'm a passenger in an unpressurised plane to test my unit out. I want to be 'not flying' or not the PIC and have standby oxygen on board for me. I have a finger oxygen meter which shows I have 98% to 99% O2 in me on the ground. I've also bought a peak flow meter so I have a base line for my lung capacity to ensure I'm AOK on the day of the flight.
I'm still trying to organise this. I shall report back to you! Meanwhile I'm only thinking of how and where to install this unit for my world trips. With no O2 bottles to get filled, travelling life would be easier. The unit can be powered from the plane's 14volt power and it has its own 4 hour backup battery that fits on the bottom of the unit (as pictured).
