Jennifer Sutcliffe and her husband were doing weekend yard work when she spotted a 4-foot rattlesnake.
When he picked up the snake's remains to dispose them, the head bit him. "He had to rip it off".
"There are about 6,000 to 8,000 snake bites per year in the country, and 10-12 people die", trauma surgeon Michael Halpert told Kiii TV.
"They HALO-Flighted him into the hospital", Sutcliffe said, explaining she could not get to the emergency room quickly enough so met with an ambulance en-route.
"Within two miles down the road, he was going through seizures, slipping out of conscious and couldn't see".
Mrs Sutcliffe said her husband needed 26 doses of antivenom, where a normal patient gets two to four doses. Upon spotting a four-foot rattlesnake, the man (unnamed in media reports) severed its head with a shovel.

He was eventually airlifted to Christus Spohn Shoreline Hospital, she said.
However, he is still experiencing weak kidney function more than a week after the incident.
If you thought cutting the head off a venomous snake made them safe to handle, think again.

The bite reflex is stronger in venomous snakes than it is in some other carnivores because these snakes use their bite differently than other meat-eaters, Beaupré said.
He also encouraged people never to suck out the venom as characters in TV shows and movies often do.
