Computers recorded every move Timmy made.
"These leads actually measure two basic things — they measure your brain activity so that we can actually figure out whether you're awake or asleep," Bhargava said. "We also look at how they breathe, how fast they breathe, whether they stop breathing, whether their oxygen level goes down, whether their limbs move excessively at night."
And while it may seem intimidating, it's a painless and simple overnight procedure, which could prevent a lifetime of problems for Timmy.
While Timmy was monitored, Bhargava discovered in the boy's deepest sleep stage that he had some obstruction to his air flow.
But Bhargava's definitive diagnosis included some good news.
"He said he did have a mild sleep apnea," said Vail. "It was so mild that we don't need to have his tonsils out right now. However, in about six months, he wants to recheck him with another sleep study."
