A U.S. hiker who was rescued after being lost overnight in a whiteout on Mount Rainier National Park has been brought back to life after what his medical team is calling an amazing recovery.

The Seattle Times reports that 45-year-old Michael Knapinski, of Woodinville, died in the emergency room at Harborview Medical Center after being airlifted off the mountain last Sunday.

He had a pulse when he arrived at the hospital but soon his heart stopped, said Dr. Jenelle Badulak, one of the first people to start treating him.

“He died while he was in the ER, which gave us the unique opportunity to try and save his life by basically bypassing his heart and lungs, which is the most advanced form of artificial life support that we have in the world,” Badulak said.

The medical team repeatedly performed CPR and hooked him up to an extracorporeal membrane oxygenation (ECMO) machine, which pumped blood out of his body into a heart-lung machine that removes carbon dioxide, and then back into the body.

His heart remained stopped for 45 minutes. After the doctors restarted it, the medical team spent the night beside him to make sure he continued to stabilize.

Two days later, Knapinski woke up. Trauma nurse Whitney Holen was there and said the first thing he wanted was to call his family.

“He was crying and they were crying and I’m fairly sure I cried a little bit,” Holen said. “It was just really special to see someone that we had worked so hard on from start to finish to then wake up that dramatically and that impressively.”

She added, “It reminded me of this is why we do this. This is why we are doing the long hours, this is why we’re away from our families, this is why we’re here.”

He continued to have some trouble with his heart, kidneys and frostbite, but doctors said they believe he’ll be OK. He remained in the hospital Saturday.

Knapinski had left for a snowy hike with a friend on the morning of Nov. 7. His friend planned to ski down the mountain to Camp Muir, while Knapinski was going to snowshoe to Paradise.

“I was pretty close to the end [of the trail] … Then it turned to whiteout conditions, and I couldn’t see anything,” Knapinski told The Seattle Times in a phone interview Friday. The last thing he remembers is taking baby steps down the mountain, surrounded by white.
