Insights
Real-time, second-by-second oxygen monitoring in neonatal intensive care provides a more accurate picture of infant oxygen exposure than hourly spot checks. This improved data aids in managing oxygen levels to prevent retinopathy of prematurity.
Area of Science:
- Neonatal Medicine
- Biomedical Engineering
- Healthcare Analytics
Background:
- Maintaining optimal blood oxygen saturation in preterm infants is critical for neonatal intensive care.
- High oxygen levels are linked to an increased risk of retinopathy of prematurity, necessitating careful management.
- Current methods using hourly spot readings offer limited insight into oxygen fluctuations.
Purpose of the Study:
- To evaluate the efficacy of a real-time healthcare analytics platform (Artemis) for monitoring oxygen saturation.
- To determine if second-by-second data collection provides a more accurate representation of retinal oxygen exposure compared to intermittent readings.
- To improve the understanding of oxygen fluctuation ranges affecting infant physiological status.
Main Methods:
- Utilized the Artemis platform for real-time, second-by-second data collection on oxygen levels.
- Compared high-frequency data from Artemis with traditional hourly spot readings.
- Analyzed data to assess the representation of oxygen exposure and fluctuations.
Main Results:
- Artemis successfully collected high-frequency, second-by-second oxygen saturation data.
- The platform provided a more accurate representation of retinal oxygen exposure than intermittent spot readings.
- High-frequency data captured episodic events and revealed detailed oxygen fluctuation ranges.
Conclusions:
- Real-time analytics platforms like Artemis offer superior data accuracy for monitoring neonatal oxygenation.
- Second-by-second monitoring enhances the understanding of oxygen fluctuations critical for infant care.
- This approach can lead to better management strategies for preterm infants at risk of retinopathy of prematurity.
Abstract:
Maintaining blood oxygen saturation within the intended target range for preterm infants receiving neonatal intensive care is challenging. Supplemental oxygen is believed to lead to increased risk of retinopathy of prematurity and hence managing the level of oxygen within this population is important within their care. Current quality improvement activities use coarse hourly spot readings to measure supplemental oxygen levels as associated with targeted ranges that vary based on gestational age. In this research we use Artemis, a real-time online healthcare analytics platform to ascertain if the collection of second by second data provides a better representation of retinal exposure to oxygen than an infrequent, intermittent spot reading. We show that Artemis is capable of producing more accurate information from the higher frequency data, as it includes all the episodic events in the activity of the hour, which provides a better understanding of oxygen fluctuation ranges which affect the physiological status of the infant.
