It's not the oxygen that causes unconsciousness, it's bubbles that get stuck in arteries in the brain and blocking blood flow that causes unconsciousness.

Those sound like the same thing to me -- blocking the flow of arterial blood is blocking the flow of oxygen. If I'm wrong, then I'm probably missing something about the physiology here, would you care to elaborate a bit on this?

Aha. I had forgotten what AGE actually stands for, and was thinking that it was a lung embolism, hence responding with (c), since coughing up blood is likely a lung problem. But the "A" in AGE stands for "arterial," so we would be looking for problems delivering freshly-oxygenated blood, and sudden unconsciousness is of course one of those. I stand corrected, thank you for clarifying!

I stand corrected as well.

You are correct. I misread what you wrote.

Fair enough
