I found this interesting: This may not be viral pneumonia related to a SARS, but hypoxia from O2 starvation like altitude sickness. Increasing PEEP is causing more harm than good. The iron thing now makes total sense    therein -CovFeFe. COVid and Fe2 and Fe3   COVID is oxidation/reduction reaction gone amuck - therefore no O2 exchange. All the forced air from increased PEEP is useless because the hemoglobin is working with defective heme. The treatment is causing even more damage on top of the destruction from the excess rogue iron - that explains the rapid organ failure cascade attributed to cytokine storm.
