What is it about?
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.

Why is it important?
Automated oxygen systems with non-invasive respiratory modalities can minimise time spent out with oxygen target range for vulnerable neonates. There can be long term impact of automated control on minimising the incidence of oxidative stress injury occurring within the neonatal population.
Perspectives
This article was adapted from a student master's dissertation completed as part of an advanced neonatal clinical practice award. It was an opportunity to put into action a theoretical study in order to support clinical practice to optimise outcomes for this vulnerable population.
