I just took the re-cert for PSI-PCI and one of the slides referenced some medical data about people on home oxygen therapy and the burns they sustain.
I don't recall the numbers, but this website estimates that about 20% of patients on home oxygen are still smoking. And medicare is reporting 685 patients were treated for burns related to home oxygen and smoking between 2001 and 2010. Anyway, I found thos stats surprising for some reason.

The sad part about the chamber in China is that they had back log of patients and that chamber made getting treatment even more difficult.
