A medical expert in Derek Chauvin’s murder case revealed that the late George Floyd died due to lack of oxygen resulting from being pinned facing downwards with hands cuffed behind him.
According to Dr Martin Tobin who is a lung and critical care specialist at the Edward Hines Jr VA Hospital, the late could not take in enough oxygen while on the ground leading to abnormal heart beat and brain damage.
“Mr Floyd’s breathing while he was being held down by Chauvin and other officers was too shallow to take in enough oxygen, which in turn damaged his brain and caused an abnormal heart rhythm that made his heart stop.” said Dr Martin Tobin.
This medical expert made these sentiments in a bid to justify efforts by prosecutors to draw a link that Chauvin’s actions and not George Floyd’s drug abuse and underlying health condition led to his death. In the meantime, the defense has maintained that the 46 year old George Floyd died as a result of existing health conditions and drug abuse.
Dr Martin Tobin while analyzing a graphic presentation of the three officers pinning the late Floyd for almost 9 minutes, said that the knee was “virtually on the neck for the vast majority of time”.
He added that it was “more than 90% of the time in my calculations”.
He further revealed that Floyd was getting sufficient oxygen during the first five minutes to keep the brain alive since he was still speaking and pleading with officer Chauvin to let him free.
According to Dr. Tobin, breathing becomes enormously more difficult as the space in the airways narrows, revealing to the jurors that it would be worse than “breathing through a drinking straw”.
He also gave evidence that if the hypopharynx, the bottom part of the throat, becomes totally obstructed, it takes just seconds to reduce the level of oxygen to where it would result “in either a seizure or a heart attack”.
