Article Synopsis
- The study focuses on caregiver responses to cardiorespiratory events in preterm infants in the Neonatal Intensive Care Unit (NICU).
- Researchers observed 19 preterm infants over 72 hours, recording 1851 cardiorespiratory events, with most (91.5%) not receiving any caregiver intervention.
- When interventions occurred (8.5% of events), caregivers typically paused alarms or provided tactile stimulation, with an average response time of about 25 seconds, and stimulation methods varied significantly.
Article Synopsis
- The study aimed to compare the effects of two target ranges for peripheral oxygen saturation (SpO) on hypoxic and hyperoxic episodes in infants receiving respiratory support.
- Conducted in a neonatal unit in the Netherlands, the randomized cross-over study involved 27 infants, assessing their oxygen levels while using the OxyGenie controller.
- Results indicated that while a higher SpO target range (92%-96%) reduced the frequency of hypoxic episodes, it also increased the frequency of hyperoxic episodes, suggesting the potential of automated oxygen titration in neonatal care.
Unlabelled: Faster resolution of hypoxaemic or hyperoxaemic events in preterm infants may reduce long-term neurodevelopmental impairment. Automatic titration of inspiratory oxygen increases time within the oxygen saturation target range and may provide a more prompt response to hypoxic and hyperoxic events. We assessed routinely performed follow-up at 2 years of age after the implementation of automated oxygen control (AOC) as standard care and compared this with a historical cohort.

- - The study aimed to assess how two different automated oxygen control devices (OxyGenie vs. CLiO) impacted the oxygen saturation levels of preterm infants in the NICU.
- - Data was analyzed from preterm infants born between 24-29 weeks who received respiratory support, and it showed that those under OxyGenie had significantly better oxygen saturation control and spent more time within the desired range (91-95%).
- - Results indicated that OxyGenie managed to reduce the time infants spent in both hypoxic (too low oxygen) and hyperoxic (too high oxygen) states compared to CLiO, highlighting its effectiveness in neonatal care.
Article Synopsis
- * Researchers processed one-per-second oxygen and saturation data into one-per-minute intervals to analyze various statistical outcomes.
- * Results indicated that one-per-minute data produced outcomes nearly identical to one-per-second data, suggesting that this lower frequency data can be reliably used for retrospective studies and analyses.
Clinical outcomes of preterm infants while using automated controllers during standard care: comparison of cohorts with different automated titration strategies.

Objective: To compare short-term clinical outcome after using two different automated oxygen controllers (OxyGenie and CLiO).
Design: Propensity score-matched retrospective observational study.
Setting: Tertiary-level neonatal unit in the Netherlands.
Aim: Heart rate (HR) is the most important parameter to evaluate newborns' clinical condition and to guide intervention during resuscitation at birth. The present study aims to compare the accuracy of NeoBeat dry-electrode ECG for HR measurement with conventional ECG and pulse oximetry (PO).
Methods: Newborns with a gestational age ≥32 weeks and/or birth weight ≥1.
For the preterm infant with respiratory insufficiency requiring supplemental oxygen, tight control of oxygen saturation (SpO) is advocated, but difficult to achieve in practice. Automated control of oxygen delivery has emerged as a potential solution, with six control algorithms currently embedded in commercially-available respiratory support devices. To date, most clinical evaluations of these algorithms have been short-lived crossover studies, in which a benefit of automated over manual control of oxygen titration has been uniformly noted, along with a reduction in severe SpO deviations and need for manual FiO adjustments.

Objective: To compare the effect of two different automated oxygen control devices on target range (TR) time and occurrence of hypoxaemic and hyperoxaemic episodes.
Design: Randomised cross-over study.
Setting: Tertiary level neonatal unit in the Netherlands.
Several studies demonstrated an increase in time spent within target range when automated oxygen control (AOC) is used. However the effect on clinical outcome remains unclear. We compared clinical outcomes of preterm infants born before and after implementation of AOC as standard of care.

Automated oxygen control in preterm infants, how does it work and what to expect: a narrative review.
Arch Dis Child Fetal Neonatal Ed
March 2021
Background: Automated oxygen control systems are finding their way into contemporary ventilators for preterm infants, each with its own algorithm, strategy and effect.
Objective: To provide guidance to clinicians seeking to comprehend automated oxygen control and possibly introduce this technology in their practice.
Method: A narrative review of the commercially available devices using different algorithms incorporating rule-based, proportional-integral-derivative and adaptive concepts are described and explained.
