I have an Inogen and it has failed many times. The first time I called the company and had a replacement the next day. During the same phone call I was told how to jump start if I have too. You can take the battery off then put back on. Sometimes it works. There are times it works independently of my breath. You can sincroniz you breath with the machine and it will slowly match your natural breath. So having these problems is a pain in the neck, I wouldn’t change having a portable oxygen.

I have an Oxygo. I have had it for several months.....not quite a year yet. So far I have had no problems with it and find it very easy to use. My oxygen levels stay where they are supposed to when I am using it. However, I have not flown with it. I find the batteries do run down quickly with heavy use. they gave me two rechargeable batteries. Since I mainly use mine when I go out, I keep a car charger with me all the time.

How did you manage when the device failed? Were you aware of your sat levels? The machines do fail, although my experience is that the failure usually comes with a warning that gives me enough time to find some temporary solution. The fact that the device failed isn't a condemnation of all Oxygo devices, nor does it mean that it isn't safe to use, it simply means that it is a machine and that machines fail sometimes. If all Oxygo devices failed at altitude that would be a major problem and it certainly wouldn't be safe to use one,.

I understand your fear and frustration. It's terrible when something that is supposed to be life-saving fails when you're in a vulnerable situation. Unfortunately, the only way you'll able to absolutely avoid that in the future is not to fly. Any of the POCs do fail after a period of time. The sieve beds can no longer do their job and must be replaced, other parts wear out. My Inogen One G2 began to fail on a flight from Tucson to Denver. I was lucky in that the company I bought it from was located in Denver and met me at the airport where I gave them my failing one for repair and picked up a new one.

The next time you use a machine to fly, I would ask how long it's been in service. If it's more than 3 years, I would ask when it was last serviced and how new the sieve beds are. That would give you some idea that the machine isn't close to giving up the ghost.

I get anxiety attacks once every few mouths thats what the doctor calls them

Does anyone besides me get the panic attacks.
