Doctor Who Treated George Floyd Says He Believed Cause Of Death Likely Asphyxia

An emergency medicine doctor who treated George Floyd the night he died testified in court Monday that he believed Floyd had died of asphyxia, the common term for oxygen deprivation.

Dr. Bradford Langenfeld made the statement during his testimony in the trial of Derek Chauvin , the former Minneapolis police officer charged with murdering Floyd on May 25, 2020.

Bystander video showed Chauvin, who is white, kneeling on Floyds neck as Floyd, who is Black, repeatedly stated that he couldnt breathe. Chauvin continued to kneel on Floyds neck for several minutes even after Floyd become motionless and ceased breathing.

Chauvin was charged with second- and third-degree murder as well as second-degree manslaughter. He has pleaded not guilty to all of the charges.

Langenfeld testified that Floyd was in cardiac arrest and absolutely suffering a medical emergency when paramedics brought him into Hennepin County Medical Center the night of his arrest. He said he tried to resuscitate Floyd for roughly 30 minutes before he officially pronounced Floyd dead at 9:25 p.m. CT.

Prosecutor Jerry Blackwell asked Langenfeld if his leading theory for Floyds cardiac arrest had been oxygen deprivation. Langenfeld said yes.

That was one of the more likely possibilities, Langenfeld testified. I felt that at the time, based on the information I had it was more likely than the other possibilities.

Asphyxia is a commonly understood term, he added when asked if there was another name for death by oxygen deficiency.

Two autopsies one conducted by county officials and the other commissioned by Floyds family separately classified Floyds death as a homicide. However, the autopsy reports, which were both released last June, differed on the exact cause of death.

The Hennepin County medical examiners office said in its report that Floyd died of cardiopulmonary arrest complicating law enforcement subdual, restraint and neck compression. The report also stated that fentanyl and methamphetamine were found in Floyds system at the time of his death. Michael Baden and Allecia Wilson, the doctors who conducted the independent autopsy, said Floyd died of mechanical asphyxia.

Chauvins attorney, Eric Nelson, has argued that Floyds death was caused in part by high blood pressure, heart disease and drug use not by Chauvin kneeling on his neck.

During his cross-examination of Langenfeld, Nelson asked the doctor if fentanyl and methamphetamine can cause hypoxia, or a lack of oxygen. Langenfeld said yes.

Earlier Monday, Langenfeld testified that the two paramedics who brought Floyd into the hospital that night Derek Smith and Seth Bravinder did not report that they believed Floyd had suffered a heart attack or drug overdose.

Langenfeld said he had considered the possibility that Floyds cardiac arrest was caused by excited delirium but dismissed that theory since the paramedics did not report Floyd being very sweaty or extremely agitated two common symptoms of the condition.

The absence of that information was telling in that I didnt have any reason to believe that that was the case here, Langenfeld testified.

He said he did not treat Floyd with Narcan a medication designed to rapidly reverse opioid overdose that night, and said the paramedics didnt report treating him with Narcan either.
