DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 23 0/7-28 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.
Bronchopulmonary dysplasia (BPD) is the most common complication of prematurity and is the leading respiratory cause of childhood morbidity. Ventilator induced lung injury (VILI) an accepted and important contributor to BPD. Exposure to oxygen and positive pressure ventilation leads to developmental arrest and parenchymal injury in the immature preterm lung. Because even brief exposure to intubated positive pressure ventilation is injurious, avoiding invasive mechanical ventilation is the most widely acknowledged strategy to prevent VILI and the long-term sequela of BPD. Therefore, time on ventilators and rates of successful extubation are important endpoints of therapy. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is an FDA approved technology that consistently synchronizes non-invasive respiratory support with infant respiratory drive. The Diaphragmatic Initiated Ventilatory Assist (DIVA) trial is an unblinded, pragmatic, multicenter phase III randomized clinical trial in extremely preterm infants 23 0/7- 28 6/7 weeks gestational age to determine if NIV-NAVA, compared with non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), prevents extubation failure within 5 days (120 hours) of extubation from mechanical ventilation

Infants in the intervention arm will be managed with non-invasive neurally adjusted ventilatory assist (NIV-NAVA) using FDA-approved servos with associated FDA-approved Edi catheter.
Infants in the active comparator arm will be treated with non-synchronized non-invasive positive pressure ventilation (NIPPV) through FDA-approved ventilators currently in use at each site.

Extubation failure
Extubation failure is defined when an infant is on the allocated mode of respiratory support and meets any of the following 4 criteria: (1) Rise in FiO2 at least 20% from pre-extubation value for \>2 hours to maintain local SpO2 targets, (2) pH ≤7.20 or pCO2 ≥70mm Hg; (3) \>1 apneic event requiring positive pressure ventilation (PPV) within 6 hours or ≥ 6 apneic events requiring stimulation within 6 hours (4) emergent intubation by the clinical team for cardiovascular instability or surgery.
Time frame: within the first 5 days (120 hours) post extubation
Bronchopulmonary Dysplasia (BPD) at 36 weeks PMA
BPD will be assessed as an ordinal outcome (none, grade 1, 2, 3), according to the NRN criteria.
Time frame: 36 weeks PMA
Death or BPD at 36 weeks PMA
Composite dichotomous (y/n) outcome of death or grade 2/3 BPD, using the NRN criteria
Time frame: 36 weeks PMA
Endotracheal intubation through 36 weeks PMA
Endotracheal intubation will be assessed 2 ways: As a dichotomous (y/n) outcome if it occurs at any time and also as days until endotracheal intubation (with censoring at 36 weeks PMA)
Time frame: 36 weeks PMA
Postmenstrual age at last invasive ventilation
Time to cessation of invasive ventilation, with censoring at 36 weeks PMA
Time frame: 36 weeks PMA
Postmenstrual age at last positive pressure support
Time to cessation of positive pressure respiratory support, with censoring at 36 weeks PMA
Time frame: 36 weeks PMA
