Nearly three weeks after Bobbi Kristina Brown was placed in a medically induced coma, doctors have reportedly removed her breathing tube.
According to CNN, the procedure supposedly took place Wednesday and Bobbi will now be ventilated through a hole in her throat. As for what the tube removal means, CNN's chief medial correspondent Sanjay Gupta said it lowers the risk of infection and is a standard procedure. "This is an indication that the patient will need this for weeks and months to come, as opposed to hours and days," he said.
The procedure also protects the vocal cords and helps keep the lungs clear of fluid, according to
USA Today. Sources close to Bobbi's family told CNN doctors are attempting to lift her coma, but the extent of her injuries isn't known. An official update on Bobbi's status has not been released.
Although an official update on Bobbi's status hasn't been given, sources told People her condition hasn't changed. "She is still critical and we don't know what the outcome will be," the source added. "No one is giving up on this kid."
Police are now treating the case as a criminal investigation. The 21-year-old was found in a filled bathtub in her home Jan. 31 in Riverdale, Ga.
