Prognosis nullPrognosis of acute respiratory failure caused by uncomplicated sedative or narcotic drug overdose is excellent
Acute respiratory failure in patients with COPD who do not require intubation and mechanical ventilation has a good immediate prognosis
Course & PrognosisnullARDS associated with sepsis has an extremely poor prognosis, with mortality rates of about 90%.
Survival rates of 62% to weaning, 43% to hospital discharge, and 30% to 1 year after hospital discharge.
