I distinctly remember months ago of a Chinese doctor in China claiming this same thing. I thought it was a bit far fetched at the time but I'm getting incredible deja vu with this new release.

It's not just the Chinese. Doctors have been concerned about the abnormally high death rate for ventilators for months too. I've been seeing comments to the effect of looking for alternatives to ventilators because there were indications that did more harm than good. I guess not every hospital had this idea, but I know the sentiment was around for a while.
