"Is he breathing?" the dispatcher asks.
"I can't ... I can't tell. I can't hear anything," Julie Gans responds. "I'm trying to feel for a pulse."
Julie Gans leaves the phone for about 60 seconds to get her son to help move the 52-year-old Gans from the bed to the floor, and at Flatt's instruction begins chest compressions. As she moves, Julie Gans counts, "one, two, three, four, five ..." for almost three minutes until police arrive.
"Keep going," the dispatcher coaches. "You're doing a great job."
Police arrived about seven minutes after the call was placed.
Clark County Coroner Mike Murphy earlier ruled Gans' death was accidental.
The five-page police incident report - also released Thursday - provides no new medical information about the death of the marquee singer, actor and impressionist.
Murphy's report June 9 said Gans died of a toxic reaction to an unspecified dose of the powerful painkiller hydromorphone, and that Gans suffered from chronic pain syndrome.
Hydromorphone is an opiate drug commonly marketed under the brand name Dilaudid.
One of Gans' doctors said later that he prescribed hydromorphone for Gans for pain five years ago, but that he didn't think Gans continued to use it.
The coroner also found Gans had heart disease caused by high blood pressure, and polycythemia - a condition opposite of anemia that results in too many red blood cells.
Henderson police spokesman Todd Rasmussen said Thursday that the investigation has been completed and the case closed Longtime Gans manager and family friend Chip Lightman said Thursday that he had no comment about the report and that the Gans family was out of the country.
Julie Gans told police Gans played golf the day before he died, then received a massage and went to bed before dinner.
She told police that she awoke about 3:40 a.m. and realized Gans was no longer snoring.
Detective Chad Mitchell said Julie Gans complied with a police request to collect Danny Gans' medications for a crime scene analyst, who Mitchell said "noted nothing remarkable."
Mitchell wrote that he found no evidence of foul play in Gans' death.
Gans was a one-time minor league baseball player who spent more than a decade working his way up to top billing at the Encore Theater at Wynn Las Vegas on the Las Vegas Strip.
His show brought impressions in rapid-fire succession - Tony Bennett, Al Pacino, Sarah Vaughan, Clint Eastwood, Rodney Dangerfield, Woody Allen, Bill Cosby, Jimmy Stewart, and even Kermit the Frog.
