A family member is a nurse treating these patients at the hospital. She was relating how the blood of covid patients has a very different color. It is very dark. Is that related to this?

EDIT: She also noted that many of the patients were breathing fine, but their pulse ox would just drop and drop.

EDIT2: really? downvotes for asking a questions and seeking info?

I am not a doctor, but if true, that sounds completely consistent with this hypothesis (deoxygenated blood is darker, and being able to breathe won't help if your hemoglobin can't carry oxygen)

I would be fascinated to hear their take on this article.
