Dr. a lung specialist Martin Tobin testified that “there was absolutely no way” that Floyd’s chest could extend properly to breathe.
During his testimony, Tobin was shown a series of still images from camera footage of him wearing the body from the scene he had previously reviewed. At one point, Tobin noted the importance of an image, where you see Floyd walking out with his squad while the squad was pressed against the tire of the car, while Chauvin is on top of him.
Tobin said, “For most people, it doesn’t look very important. But for a physiologist, it’s exceptionally important.”
“It tells you that he has used his resources and now he is literally trying to breathe with his fingers and knuckles,” he said.
He continued: “Because when you start breathing, you start breathing with your rib cage and your diaphragm. Then the next thing you recruit is your sternal muscle which is big in your throat. Muscles. When they go in vain, then. Then you’re relying on these kinds of muscles like your fingers to stabilize and stabilize your entire right side. Because it’s completely dependent on the air on the right side. is. ”
Tobin said he concluded that Floyd tries to use his fingers and his knuckles against the road and cranks the right side of his chest.
“This is his only way to try and get air into the right lung,” he said.
To his left, Tobin said, Floyd was similarly using his shoulder to breathe. He said that “because it has so much expansion of the underlying chest, you get very, very little air.”
He said, “This is a very bad way to breathe. But you have to do it when everything else is failing.”
