AP Photo/Evan AgostiniTranscripts have been released of the 911 call made while transporting Natasha Richardson to the hospital almost four hours after her fateful skiing accident.
"I'm arriving with a female in her 40s... [she's] disoriented… It's following... a ski fall that happened at noon," the medic radioed to the hospital nearest to Quebec's Mont Tremblant ski resort. "Soon afterward she presents signs of confusion, a concussion."
The actress' vital signs were normal during the 4 p.m. ambulance ride on March 16, but she was extremely dazed and needing oxygen to help her breath, according to the dispatch calls obtained by the Toronto's The Globe and Mail.
Richardson, 45, had taken a spill during a private lesson on the bunny slope.
Tapes also show that medics received an emergency call soon after the accident, labeled "Priority 3, 17-Bravo-1," which is paramedic speak for "get here immediately, possibly dangerous injury."
They arrived at 1 p.m. but there was no one to treat.
"Uhh, we're still waiting for the patient," said the medic upon arrival.
At 1:11 p.m., the job was cancelled. Richardson had told others she felt fine and refused medical help.
When she complained of severe headaches two hours later, the resort called 911.
This time, the call was classified a "Priority 1, 17-Delta-1," meaning the situation was now considered "dangerous" and the ambulance was required to race to the resort with sirens on.
Richardson died on March 18 of a blood clot on her brain that resulted from the impact of her fall.
