Bobbi Kristina Undergoes Tracheotomy

Doctors performed a tracheotomy on Bobbi Kristina Brown this week to adjust a breathing tube. She is still in critical condition.

A family source told PEOPLE that it was a normal procedure: "The tracheotomy is a different place for the tube to go. Everything else remains the same. It's a waiting game. The family is hoping and waiting."

Doctors had to change the breathing tube because if its down there for a long time, it may cause infection.

The family of Bobbi Kristina is not giving up on her.

It's been more than two weeks since she was found face down in a bathtub. She's been unresponsive since.

Meanwhile, her boyfriend Nick Gordon is begging the family to allow him to see her. Unfortunately, it looks he is banned. A criminal foul play investigation is currently ongoing.
