5/ Underuse of frantically-built capacity seems universal. Even @ NYC, Javits Ctr & Navy hospital ship mostly empty https://wapo.st/34CYPxk Why? Combo of “where did all the other pts go?” & hospitals have improvised (2 pts in ICU built for 1; Covid pts in ORs & recovery rooms)...
it’s a great thought. In practice you need gardenhose size catheters and lots work to keep the blood from clotting and other complications. need to ventilate lungs to allow recovery, prevent pneumonia etc. much much more more complex than standard hemodialysis.

COVID-19 presents atypically with ards as in flexible and non hardened...respiration seems normal...so why not just add the oxygen that is needed and let the lungs function on their own.

“just add the oxygen” is the hard part! Hemodialysis replace the kidneys- think how often you urinate. Breathing is continuous. Replacement via oxygenation circuit 24/7 is not natural and can be very dangerous.
