Is dr any use of usin tracheostomy if d person is unconscious for 7 dys on ventilatn n has anoxal injury? Help

Yes. Anoxic or hypoxic brain injury may lead to prolongued mechanical ventillatory support. Usually patients in that situation require a tracheostomy and a percutaneous gastrostomy tube.The tracheostomy tybe is shorter than the oro or nasotracheal tube, therefore less work of breathing, and it does not erode the vocal cords if the person is expected to ever talk again.
Possibly. Depends on the initial injury that precipitated hypoxia and duration. Depends on the overall vital signs the tracheostomy provides secure airway for movement to extended care facility hoping for any recovery. May be none! tough choices.
