Helmet-based ventilator alternative

My first thinking on this disease is it would be better to get it early when the health system is not overwhelmed. Now I am thinking later as we are learning how better to help patients in distress.
@Mik Had exactly the same thought. The entire world is working on this problem. Who knows what we'll learn in another month.

We are at last starting to look like sci-fi told me Medical treatments would look like!
Next step? Big glass tanks filled with some medicinal gel!

My surgeon friend and I were talking about how to get oxygen into patients without using a ventilator. This is obviously a good and simple solution (hope it works!). However, he suggested hyperbaric chambers.
I suppose that would work as well, but if you think ventilators are in short supply....
Then he said, "Airplanes. Widebody airplane fuselage could become a very large hyperbaric pressure chamber. Maybe not more than 2 atm but, hey it might be useful."

This makes a lot of physiologic sense if you accept the theory that COVID-19 pneumonitis is not ARDS. You oxygenate the patients by providing an extremely high-flow oxygen-rich environment. Perhaps more importantly, you don't use positive pressure to move air into the lung. Instead, normal negative pressure (when you inhale) draws air into the lung. If the lungs are compliant, as I've commented elsewhere, this would be a good and reasonable alternative.
The other thing that people are doing is putting patients prone. "Proning" patients in the ICU has been a long-standing therapeutic modality, the thinking is that it redistributes bloodflow to non-diseased portions of lung. However, it's always been done on patients who are being ventilated. Now, they're trying it with spontaneously breathing patients. Sometimes, if one lung is worse than the other, patients are positioned laterally, with the "good" lung down. Improvement is seen within hours, sometimes minutes.
This is all out-of-the-box thinking, and I'm excited to see it.

These look similar to what was shown in pics from Italy.
Indeed!
