Abstract

fetched live from OpenAlex

PURPOSE: Near infrared spectroscopy (NIRS) is an emerging technology that can measure tissue oxygen saturation levels (StO2) and has many potential clinical applications. NIRS devices have been studied in various disease states in the pediatric as well as adult populations. A review of this technology, with its potential applications and a review of current evidence is presented. PRINCIPAL FINDINGS: NIRS-derived regional tissue oxygen saturation (StO2) is superior to pulse oximetry as it measures tissue oxygen saturation and reflects imbalance between oxygen supply and local demand. Becoming more widely available, it still does not have a firmly established role due to its technical limitations and to the lack of large multi-centric randomized controlled studies necessary to confirm its utility, cost-benefit effectiveness and role in improving patient outcomes. CONCLUSION: Widespread availability, ease of use, non-invasive nature and continuous data display makes it an attractive option for bedside clinical monitoring.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
