Camden Vaughan is sick of being in the hospital room with his mom. He's ready to go home.

"He's all boy, and he's all active," Misty Vaughan said.

And if not for him, Misty Vaughan may not have been here to talk with us. She thought she had the flu. Her fever kept rising.

"It was reading 105 on my thermometer, and that's the last thing I remember," she said.

Then she passed out.

It was little Camden who found her Sunday night, and he used her cell phone to call Dr. Jeremy Vaughan — his own father.

"He said, 'Daddy I need you to come home! Mommy can't get in the bath because she can't wake up!' And I said: 'I'm on my way!'"

Remember, Camden is just four years old. But he unlocked his mom's iPhone and found his dad's photo at the the top of the favorites list.

"And tap the phone button, and the star, and hit the pictures," the youngster explained.

Misty Vaughan's physician at Methodist Charlton Medical Center, Dr. Ousama Moammar, believes she had a seizure. He also believes that Camden's phone call was crucial.

"It saved her life... as simple as that," he said. "Acting early and fast is really of the essence."

That's something that this mother of two is still trying to process.

"If my brain had continued at that temperature, I could not be the same here... the same or not be here at all for them," Misty Vaughan said.

But she is is still here, she's feeling better, and should be back at home soon with Camden.

"I feel like my trust in his responsibility has definitely increased," she said.
