It has been known for five days or so that the problem is the diffusion of oxygen and carbon dioxide passing between capillaries and red blood cells that is being hindered. The faster your blood is moving, the harder it is to exchange gases. If blood thinners result in lower blood pressure, that would make diffusion better. Because it is blood first and not lung first oxygenation issues, this would be why ventilators are dangerous to use (more stress on lung capillaries and higher blood pressure would be worse than not). This would also be the basis of why proning works. Eat some saffron and lay on your stomach with a bipap?
