简要总结
Background: fluctuation of cerebral blood flow and oxygenation in neonates who undergo intensive care is an important risk factor for risk of neurodevelopmental impairment. Near infrared spectroscopy (NIRS) allow direct measurements of cerebral tissue oxygenation. Automated Fraction of Inspired Oxygen (FiO2) adjustment can maintain arterial oxygen saturation (SpO2) within a target range and may reduce risk of fluctuation of cerebral oxygenation.
Aim of this study: to evaluate the efficacy of automated FiO2 adjustment in maintaining SpO2 within a target range and in reducing the risk of cerebral tissue hypo-oxygenation due to SpO2 fluctuations in preterm infants on invasive or non invasive respiratory support with supplemental oxygen.

Methodology: multicenter randomized cross-over clinical trial. The study will be carried out for almost 1 year .
Study centers: 7 Italian Neonatal Intensive Care Units (NICUs) Number of subjects: 60 infants to have a >90% power, with an alpha of p=0.01, of detecting a 5% difference in %-time in the target range and a 50% difference in both SpO2 hyperoxic and hypoxic %-time.
Diagnosis and main inclusion criteria: preterm infants of 25+0-28+6 weeks of gestational age, requiring invasive or non invasive respiratory support and supplemental oxygen.
