On day 5, she was weaned from the ventilator and extubated; however, significant neurological function was never regained. In accordance with her advance directive, tube feedings were discontinued. She became febrile and dyspneic. Antibiotics were started to provide comfort and relief of her pneumonia. She expired on day 13.
