That’s cus the ventilator is not the correct thing to use for Covid. Your lungs get coated with a layer of mucus that prevents the lung tissue from absorbing oxygen. A ventilator is used when your lungs are too weak to pump for themselves. Two totally different things.
So now you’ve got a machine pumping air into your lungs but it doesn’t matter cus your lungs can’t absorb the oxygen anyway. Begs the question why a ventilator is the go to treatment when the success rate is what? 10%. 20%. What about Ivermectin? I don’t want to be that guy but you can’t discount the success that entire countries have had using it. India. Japan. If someone gets some early enough it’s a done deal but here in the U.S. we just send you home until you’ve deteriorated so bad that they then put you on a ventilator to finish you off.
