Scientists are reporting that a miracle occurred after a toddler, who sustained brain damage from a drowning incident, has healed after undergoing multiple hyperbaric oxygen chamber treatments.

On February 29, 2016, when little Eden Carlson’s mother was taking a shower, the two-years old managed to climb through a baby gate and fell into her family’s backyard swimming pool. She remained there for up to 15 minutes before her family found her lifeless body.

“Her older siblings lost track of her and thought she was with me,” Eden’s mother told reporters.

When paramedics arrived on the scene and administered CPR, it took 100 minutes before Eden’s heart began beating on its own.
