DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 24-27 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

This is a phase 3 study designed to evaluate whether the administration of ganciclovir increases ventilator-free days in immunocompetent patients with sepsis associated acute respiratory failure. Our hypothesis is that IV ganciclovir administered early in critical illness will effectively suppress CMV reactivation in CMV seropositive adults with sepsis-associated acute respiratory failure thereby leading to improved clinical outcomes.
