Girl tethered to huge ventilator all her life finally free after op to help her breathe

This is the amazing moment a five-year-old girl who has spent her entire life tethered to a huge ventilator runs freely after undergoing surgery to help her breathe on her own.

Diana Galleno suffers from congenital central hypoventilation syndrome (CCHS), a rare condition affecting the autonomic nervous system which controls breathing.

As a result the little girl has been attached to a bulky 15lb ventilator - a machine to help her breathe which resembles a vacuum cleaner - since she was a week old.
