So, I was a bit wrong in my last post; upon looking at more studies it looks like non-invasive ventilation *does* reduce the risk of needing intubation.https://srconstantin.github.io/2020/03/20/non-invasive-ventilation.html …

This is good news for home CPAP-style COVID-19 devices; the chances look much better than I thought that, in a world where ICUs are unavailable, a non-invasive ventilation device could save your life.

It looks like non-invasive ventilation cuts the risk of intubation in half, relative to standard oxygen therapy, if you look at all adult cases of acute respiratory distress (which includes things like COPD, pulmonary edema, pneumonia.)

what is the difference between "noninvasive ventilation" and "oxygen therapy"?

noninvasive ventilation provides pressure. oxygen therapy is just higher oxygen concentration than room air, but no pressure.

How can you DIY non-invasive ventilation? Oxygen is dangerous (fire risk). Is there any trivial way to add pressure?

The DIY I was referring to was operating the machine, not building it.
