What's interesting is I knew about cpap machine (I mean everyone does from the ads for "sleep equipment" right?) but I didn't know there is also bi-pap machines which may be suitable for some with covid19. Some also get away with just taking in oxygen, I guess at the hospital they have to evaluate and monitor.
