Adjusting ventilator PEEP to improve lung compliance and heart function in preterm infants
Official title: Ventilator Pressure and Optimization of Compliance and Hemodynamics: VPOCH Trial
Run by University of Alabama at Birmingham · NCT06512935 · Data updated 2026-11-12
We will try changing the ventilator's PEEP settings in babies born before 34 weeks who need breathing support to see if the PEEP that gives the best lung compliance improves heart output and oxygen levels.

Is this trial a fit for you?
✓Likely a good fit
Preterm infants born before 34 weeks, more than 7 days and less than 1 month old, who are receiving invasive mechanical ventilation or HFJV for recovering RDS and whose guardians provide consent.
✕Probably not a fit
Infants with blood culture–positive sepsis, major congenital respiratory anomalies, cyanotic or ductal-dependent heart disease, those considered too unstable, on pressors or steroids for cardiac support, on non-invasive ventilation, with significant BPD and pulmonary hypertension, or with open chest wall wounds are unlikely to benefit or be eligible.

What this trial studies
This randomized crossover protocol enrolls preterm infants under 34 weeks gestation who remain on invasive mechanical ventilation or high-frequency jet ventilation and are recovering from respiratory distress. Infants are randomized to a 4-hour crossover sequence of increasing or decreasing PEEP from baseline with step changes of +1 and +2 cmH2O and a 15-minute washout before measurements. At each PEEP step clinicians will record lung compliance, oxygenation, and cardiac hemodynamics using point-of-care echocardiography and electrical impedance tomography (EIT). The approach tests whether the PEEP that yields best compliance also produces higher cardiac output and better oxygenation.
Why it matters
Potential benefit: If successful, this method could help clinicians choose ventilator PEEP that improves oxygenation and cardiac output while potentially reducing lung injury in preterm infants.
How similar studies have gone: Small physiologic studies have suggested individualized PEEP can improve lung mechanics and oxygenation, but combining point-of-care echocardiography with EIT for simultaneous lung and cardiac optimization in this population is relatively novel.
