I have O2. Medical grade and some nasal cannula's, maybe one mask.We did discuss the difference between cpap, bipap and vent just a little in the first thread.
I went out and bought the biggest bottle of oxygen for my torch that I could, after researching and learning that industrial oxygen is just fine to breath, just drier than hospital oxygen.
It sounds like to me oxygen is bad for the virus, vent is bad for the lungs.
It wouldn't be enough to last long for sustained use.
