Narrative review of closed loop automated oxygen systems
Stewart, Lyndsey; MacVicar, Sonya
Preterm infants frequently require respiratory support with supplemental oxygen but excess and fluctuation of oxygen levels can have adverse effects. Oxygen saturation levels are maintained within narrow target ranges as a manual titration process. Closed loop automated oxygen systems hypothesis that automatic titration of inspired oxygen will reduce time spent out of desired oxygen target range compared with current manual control.
comparison of automated versus manual oxygen control for preterm neonates undergoing non-invasive ventilation plus supplemental oxygen.
Four electronic databases (CINAHL, Cochrane Library, Medline and PubMed) were searched with narrative review of findings.
Four studies were included and all reported neonates spent more time in the oxygen target range with automated versus manual control with a wide variation in improvement from 8.8% to 30%.
Automated oxygen systems with non-invasive respiratory modalities can minimise time spent out with oxygen target range. Long term impact of automated control on incidence of oxidative stress injury remains undetermined.
