Survival in patients with cystic fibrosis (CF) is improving over time. Traditionally, there has been concern about high mortality in individuals with CF requiring invasive mechanical ventilation (IMV) for respiratory failure…Mortality per hospitalization in adults with CF who are not bridging to lung transplant and require emergent IMV is 44.5%, suggesting IMV is not futile. Furthermore, mortality decreased over the study period. These finding may help providers, families, and patients with CF weigh the risks and benefits of IMV for respiratory failure.
