Dr. Tobin the State's witness pulmonologist just testified that Mr. Floyd has an O2 saturation level of 98%. If that is the case - - how the hell does one have asphyxia?? If the blood is saturated with O2 when measured at the hospital how do you have O2 deficiency since it's the blood that carries the Oxygen. This doesn't make sense to this layman. Heck I've checked my O2 level with a pulse oximeter and my O2 saturation level is 97%. I guess I should be dead. Hopefully the defense can jump on that without the help of their medical experts.
