A 4-year-old boy nearly drowned on Royal Caribbean's Oasis of the Seas last night, forcing the ship to return to Port Everglades.

Mike Jachles, spokesman for Broward Sheriff Fire Rescue, said the boy "was swept under" in the pool and remained underwater anywhere between an estimated five to 10 minutes.

Cynthia Martinez, a spokeswoman for Royal Caribbean, confirmed that the 4-year old was a boy from Italy who "was rescued from one of the ship’s swimming pools."

Other guests administered CPR on the spot until the ship's medical team began more advanced life saving techniques.  Luckily, these efforts worked as they were able to restore the boy's pulse.

The boy was treated by the ship's medical team but needed additional medical care and so Oasis of the Seas returned to Port Everglades.
