It's highly variable oxygenation with patient position, implying some kind if impaired diffusion capacity, which could mean something like micro embolisms. Prone positioning wouldn't do anything for a process that was purely an impairment of hemoglobin. I'm not saying its not happening, but there it's at least something else going on in the picture
It's because they used ARDSnet criteria, and people are starting to realize it's not ARDS but some kind of shunting defect.
Dr. seemed to indicate it may be a blood virus that prevents the hemoglobin from transporting oxygen
