The problem is not the lungs. It is that the virus affects the red blood cells ability to function and deliver oxygen. Vents won’t help that at all. .

Not quite: the lung tissue cells are where the virus replicates and destroy the cells in the process; these dead cells and the fluid buildup of debris prevents the alveoli from functioning to be the environment for gas exchange; one of the reasons smokers and COPD patients are usually doing worse than others. This virus is not like any other I have ever studied. It is a two prong killer.
