Joan Rivers' death may very well have been preventable.
According to the report, doctors involved in the procedure continued working on her throat with a surgical instrument despite plummeting vital signs.
The doctors also allegedly delayed calling 911 for at least 10 minutes and instead tried to revive her themselves, this according to the New York Post. Dr. Lawrence Cohen from Yorkville Endoscopy and Joan's own ENT, Dr. Gwen Korovin, attempted to resuscitate Rivers, but failed.
“She had no heartbeat, no pulse, she wasn’t breathing,” one insider said of Rivers’ condition when first responders finally arrived at the Upper East Side clinic at 9:47 a.m Aug. 28.

“She had cyanosis around the lips and the mouth — that’s when your lips turn blue from lack of oxygen,” said the source, who spoke on condition of anonymity. “That takes several minutes without oxygen.”

The Post report says even before Joan went into cardiac arrest, her pulse and blood pressure were dropping quickly, but the doctors continued scoping her larynx and trachea for those 10 minutes that were critical.
Rivers' pulse also reportedly sank to 47 prior to the anethesiologist administering Propofol.
TMZ broke the story of a federal report which says there were major problems with the amount of Propofol used on Rivers.
Apparently, the Department of Health and Human Services examined the Yorkville Endoscopy Center, where Joan stopped breathing. The department found no record of the staff weighing Rivers before administering the Propofol, which determines the amount of sedative necessary for a patient.
Dr. Korovin and Dr. Cohen have not responded to reports detailing alleged errors during the procedure.
