Fyi, This is grossly oversimplifying things. Ventilators absolutely work to treat hypoxia, which is why they were picked in the first place. There are many causes of hypoxia though, and traditional ARDS strategy was the wrong choice for this disease process that still isn't fully understood. There are characteristic lab abnormalities that happen and major concerns of DIC. Some initially claimed it was a hemoglobin binding issue, but that fails to explain low PaO2/FiO2 ratios - since PaO2 is the dissolved O2 in plasma and doesn't involve hemoglobin as a factor. There is clearly a perfusion related V/Q abnormality
Hypoxemia and hypoxia are not the same, but one is usually the cause of the other. Ventilators treat hypoxia by resolving hypoxemia. I didnt disregard what you said.
