Key takeaways in the Derek Chauvin trial in George Floyd's Departure, Day 9

"Mr. Floyd died from a very low amount of oxygen," said a professional witness.

A world-renowned pulmonologist, who penned the bible on fixing breathing ailments, testified Thursday that George Floyd died from a lack of oxygen to his mind leading to prior Minneapolis police officer Derek Chauvin jamming his knee to the back of Floyd's throat as he laid trapped into the floor in handcuffs.

Tobin, who stated he is not being compensated for his testimony, utilized images and 3D pictures to direct jurors through a collection of demonstrations that exemplified the dreadful death Floyd endured. Tobin even supplied a second-by-second deadline revealing that the exact moments the 46-year-old Black guy lost consciousness, ceased breathing and endured a traumatic, irreversible brain injury.

"Mr. Floyd died out of a very low amount of oxygen.

He testified he based his view on clinical and investigative signs that included countless viewings of hundreds of videos, filmed from various angles, that revealed Chauvin and two additional officers carrying a handcuffed Floyd into the sidewalk just following 8 pm on May 25 out a Cup Foods shop in south Minneapolis.

Tobin, author of a 1,500-page periodical titled"Principles and Practice of Mechanical Ventilation" -- explained by the medical journal The Lancet as the bible on the subject -- stated the way of Floyd's departure is frequently known as asphyxia.

Inspired by prosecutor Jerry Blackwell when he'd formed an opinion"to a reasonable degree of medical certainty" about what triggered Floyd to endure a fatal reduction of oxygen,'' Tobin replied it had been shallow breathing to the point at which air was not able to make it through his lungs and the lower areas of the respiratory tract which filters carbon dioxide out.

Tobin testified Floyd's shallow breathing has been the direct outcome of being handcuffed at a vulnerable position"and then he has a knee on his throat, and then he has a knee onto his back and down his side."

The doctor said Chauvin's left knee was around the rear of Floyd's neck for at least 90 percent of eight minutes and 29 minutes prosecutors said Floyd was controlled on the floor. Tobin said the former officer's right knee was around Floyd's rear or rammed against the left side of his torso for at least 57 percent of their time.

He said throughout the whole incident, Chauvin and former officer J. Alexander Kueng implemented extra force by yanking Floyd's handcuffed wrists high behind his back.

Tobin stated Floyd basically was squeezed to death as though he had been in a vice.

Throughout the ordeal, Floyd, who had been arrested for the misdemeanor crime of supposedly using a bogus $20 bill to get smokes, repeatedly shouted ,"I can not breathe" and complained of pain in his belly, back and neck.

The Precise moment Floyd expired
Reviewing a photograph revealing Chauvin's left knee on Floyd's neck, Tobin noticed that at one stage that the officer's left boot has been lifted off the floor and half of his weight was pressing down on the guy.

"So, we are carrying half of his body weight in addition to the weight of... half of the equipment, and all that is coming down Mr. Floyd's neck," Tobin said.

Tobin ruled out the chance that the fentanyl discovered in Floyd's system throughout the autopsy played a part in his departure since he had a regular respiratory rate once the restraint started, which fentanyl, or at least a substantial dose of that, would have diminished his respiratory rate.

Tobin also stated his investigation rejected the risk that Floyd, who suffered from coronary cardiovascular disease, died from a sudden heart attack. If this were the situation, Floyd could have probably complained about chest pains, and his respiratory rate could have skyrocketed.

Sometimes throughout his testimony, Tobin asked jurors to put their palms on their throats as well as also the back of their necks as he talked of particular areas of the entire body. Defense lawyer Eric Nelson objected, prompting Judge Peter Cahill to inform the jury that they weren't bound to follow the physician's instructions but might if they wanted to.

In a dramatic moment, Tobin noticed that the specific instances Floyd went unconscious, stopped breathing and died. At 8:22 p.m. and 22 minutes May 25,'' Tobin said,"That is the moment that the life goes from his body"

He explained that even though the officers assessing and recognizing Floyd no longer had a heartbeat, Chauvin maintained his knee smashed into Floyd's neck to the following 2 minutes and 44 seconds, before paramedics came and place Floyd's dead body onto a gurney.

Throughout cross-examination, Nelson requested Tobin if he was conscious that Hennepin County Medical Examiner Andrew Baker, whom prosecutors intend to call to the witness stand on Friday, saw no bruising on Floyd's neck nor some harms to his hypopharynx.

"I am conscious," Tobin replied.

Nelson contested Tobin on his view that fentanyl played with no medical part in Floyd's departure. The defense attorney asked a hypothetical question of if summit fentanyl respiratory depression happens five minutes following ingestion.

On redirect questioning, Blackwell requested Tobin why no bruising had been discovered on Floyd's neck or harms to his hypopharynx.

"I would not expect anything available there," he stated,"since the consequences aren't something which will stay in the time of autopsy."

Daniel Isenschmid, a forensic toxicologist for your NMS Labs in Pennsylvania, testified he was requested by the Hennepin County Medical Examiner's office to check blood drawn from Floyd's entire body the night that he died.

He said he found 5.6 nanograms of norfentanyl, or metabolize fentanyl, in Floyd's blood samples in addition to traces of caffeine and THC, the primary psychoactive chemical in marijuana.

Smock, testifying as a paid prosecution specialist, stated medical records he examined showed that Floyd was a chronic drug user for many years and had built up a tolerance to fentanyl and methamphetamine.

He said the drugs found in Floyd's procedure throughout the post-mortem evaluation were not at rates close to those needed to allow him to overdose.

"The further you use any medication -- in this scenario, fentanyl -- you develop that endurance, therefore it requires more medication to provide you with that high, to influence your mind," Smock said.

He explained that'd Floyd been suffering from an overdose, he'd have been almost comatose, probably snoring and not able to talk to the officers.

"He gave proper answers: Title, date of arrival," he explained, describing what he saw videos revealing Floyd's arrest. "He knew exactly where he was and what he had been doing, and reacted appropriately to the questions which were asked of him"

Smock also stated he found no signs which Floyd potentially died of a sudden heart attack nor his departure was the consequence of excited delirium, a psychiatric and physical condition that creates an imbalance within the mind and induces some individuals to display"superhuman strength"

Smock went via a 10-point checklist utilized to ascertain if someone is undergoing excited delirium, such as feeling overly hot, sweating excessively, breathing quickly, feeling an odd attraction to mirrors and glass, and even failing to react to some police presence. He explained that somebody experiencing excited delirium would show at least six of the 10 symptoms.

"So, Dr. Smock," Blackwell, the prosecutor, asked,"when we must get a minimum of half those items -- six of 10 for excited delirium -- just how many did you watch?"
