I'm not sure how active this forum is anymore, but I was thinking about the George Floyd trail over the weekend and I was wondering if anyone knows what happens to blood oxygen levels in a slow asphyxiation.
I missed it earlier in all the chaos surrounding the prosecution bringing in evidence that the judge specifically barred them from presenting. But in their attempt to prove that Floyd did not die due to the car's exhaust they produced info saying that Floyd's blood oxygen levels were at 98% when he died.
Am I wrong in being surprised that someone could be slowly choked to death and have that high of an oxygen saturation? I admit this is something well outside of my area of expertise but it sounds to me like the best evidence I've heard yet to suggest sudden cardiac arrest as the cause of death. Again, I don't know much about this, but I know that the body is always putting CO2 into the blood and taking Oxygen out, so if he was having issues breathing and expelling CO2 and taking in new Oxygen it would make sense to me to hear that his oxygen levels would be down and his CO2 (and other gases) would have been higher.
Any thoughts on this? Did the prosecution unwittingly just prove that their entire case is moot? Am I just crazy? Would love to hear anyone's thoughts on this.
