Members of a surgical team are opening up about saving the lives of numerous people following Sunday's Las Vegas massacre.
Surgeon Matthew Johnson told Inside Edition everything was "extremely organized chaos."
Inside Edition spoke to 11 members of a surgical unit at Sunrise Hospital Medical Center, where 214 patients were treated. There were 15 fatalities. They treated more victims that any other hospital in Las Vegas.
The chaos began shortly after 10 p.m. Sunday, nurse Rudy Espinoza said.
"All of a sudden, the dam broke open with a rush of people with gunshots and everything and you realized this is horrific," he said.
At first, the team couldn't believe what was happening.
"It was head trauma after head trauma, non-stop. Until I left that morning, I didn't even stop to think about what is actually going on because it was just patient after patient and it was pretty horrific," recalled another nurse, Keesha Marmande.
The shower of automatic gunfire inflicted horrific wounds, surgeon Kelly Kogut said.
"The destruction from the high velocity wounds — I will never forget that," she said.
Many of the victims had no identification on them because they had lost their wallets as they rushed to get away from the gunfire. Others were in such shock that they couldn't communicate.
Fabian Salazar found himself comforting terrified family members desperately searching for their loved ones.
"It was a waiting room full of frantic, scared faces," he said.
The team worked non-stop. Many hours passed before the magnitude of the tragedy finally hit them.
"I wasn't overwhelmed until I actually left the hospital. Once you stop to think, everything hit you like a ton of bricks," said nurse Robert Erickson.
