@windwalker Hi Terri, I had no idea how a ventilator worked when I wrote that. I thought maybe it pumped air/oxygen into the lungs, like through the tube used with a nebulizer. I just read more about ventilators and they're far more complicated and more controlled than that. Personally, I don't want to be on a ventilator because of the sometimes permanent and very damaging side effects. From what I've read only a small percentage of people on ventilators with Covid-19 survive and there are have recently been questions by some doctors about whether ventilators help or harm for Covid-19. At this point, I'd rather just take my chances with IV vitamin C (started early), oxygen, and proning. See, e.g., https://www.nytimes.com/2020/04/14/nyregion/new-york-coronavirus.html
