Insights
Pulse oximetry screening (POS) effectively detects critical congenital heart defects (CCHDs) early, reducing mortality. This review examines various POS screening algorithms and potential improvements for CCHD detection.
Area of Science:
- Neonatal screening
- Pediatric cardiology
- Public health interventions
Background:
- Pulse oximetry screening (POS) is a non-invasive method for early detection of critical congenital heart defects (CCHDs).
- POS is cost-effective, widely accepted, and proven to reduce CCHD mortality.
- International adoption of POS is increasing, yet algorithm consensus is lacking.
Purpose of the Study:
- To review existing pulse oximetry screening algorithms for CCHDs.
- To compare the advantages and disadvantages of different POS algorithms.
- To explore potential modifications for enhancing CCHD detection.
Main Methods:
- Literature review of pulse oximetry screening algorithms.
- Analysis of algorithm variations, including perfusion index and machine learning.
- Evaluation of algorithm effectiveness in CCHD detection.
Main Results:
- Several POS screening algorithms exist, but no single consensus has been reached.
- Variations in algorithms present distinct advantages and disadvantages.
- Modifications like perfusion index and machine learning show promise for improved CCHD detection.
Conclusions:
- Pulse oximetry screening is a valuable tool for early CCHD detection.
- Further research into optimizing POS algorithms is warranted.
- Technological advancements may significantly enhance future CCHD screening accuracy.
Abstract:
Pulse oximetry screening (POS) is a simple non-invasive tool which enables the early detection of critical congenital heart defects (CCHDs). POS has moderate sensitivity and high specificity; it is cost-effective, readily accepted by parents and healthcare professionals, and its introduction significantly reduces mortality from CCHDs. As a result, most high-income countries and many middle-income countries have introduced, or are considering introducing, POS. Despite the international uptake of POS, there is still no consensus regarding the most appropriate screening algorithm, although several have been described. In addition, this review will consider the variations-and their relative advantages and disadvantages-between POS algorithms and also explore how modifications to existing algorithms-such as the addition of a perfusion index or the incorporation of machine learning-may have the potential to improve future detection of CCHDs.
