Earlier quoted context omitted.
How is you experience with oxygen? I can imagine it helps without stress to the lungs, which lung ventilators might introduce?
I've never been put on oxygen. A downside of oxygen is that it's very flammable. Also, to whatever degree it involves a cannula, masks, etc, it has some of the same issues in terms of sterility challenges. I've generally relied on things like airway clearance and dietary intervention in recent years.
Nit: oxygen is not flammable. Other things are flammable in its presence. A lump of coal, for example, burns white hot when oxygen is blown on it from a welding torch.
