What's an extubation

An extubation is the process of removing a breathing tube from a patient's airway. This is often done once a patient is no longer in need of mechanical ventilation or assistance with breathing. Extubation can be a delicate procedure that should be performed by trained medical professionals to ensure the patient's safety.

Does that mean they're dead

No, extubation does not mean that a patient is dead. Extubation is a common medical procedure done to remove a breathing tube in a controlled manner once a patient no longer requires mechanical ventilation or assistance with breathing. Extubation is typically performed on conscious and stable patients who are able to breathe on their own.
