| I made some remarks about ventilator alternatives here: https://news.ycombinator.com/item?id=22624959 To pull out some pertinent details: Ventilators for covid19 seem to be mostly for inflammation and fluid in the lungs (aka pneumonia), not lung or chest paralysis. If you need a ventilator due to inflammation or fluid build up, you can do other things to address those issues. If you are doing home care for serious lung issues, a downside of mechanical intervention is that you probably don't know how to adequately sterilize your equipment. This means nasty stuff grows on the equipment and then this nasty stuff gets delivered directly into the lungs. So I'm not thrilled to pieces to see the emphasis on "ooh, shiny!" homemade technical solutions in place of non-invasive home care. You can do lung clearance without mechanical intervention. This can make a ventilator unnecessary. You can do lung clearance easily on your own in the shower by standing with your feet shoulder-width apart or a bit wider, bending over as far as you can and coughing hard. If you bring up a lot of fluid from the lungs, it looks and feels a whole lot like vomiting. My sons and I call it "puking up a lung." Inflammation can be combated with commonly available non drug remedies, like caffeine, lettuce, avoiding pro inflammatory foods (avoid peanut oil like the devil himself made it for you, limit or avoid bacon as it is hard on the lungs). Etc. Please see my previous remarks about best sleeping positions, etc. I am very concerned that homemade ventilators are going to become a source of secondary infection and this secondary infection will be worse than covid19 because it will be bacterial or fungal and it will be antibiotic resistant. If I had any idea how on Earth to start a counter movement, I would be all over it. I have no idea how to do that, so I occasionally leave a comment on HN giving some of my thoughts, which isn't likely to exactly catch fire. This is today's comment in that vein. |
It sounds like a lot of these vents will end up in the hands of medical professionals. We're looking at a future with warehouses or stadiums full of sick individuals, and also a future where everyone will be pulled from every specialty to work on COVID-19, so there is some evidence that trained professionals and patients will outnumber commercial ventilators. Depending on how many people get sick at once, we could easily end up in a situation where the patients waiting outside are so numerous that they could consume as much equipment as anyone could put together, no matter how much the real manufacturers ramp up production.
