039 Determination of Burn Depth using near Infrared Spectroscopy
Bibliographic record
Abstract
Introduction : Burn depth, based on the hemodynamic alterations that occur following a thermal insult, can be assessed in a rapid, non‐invasive, and nondestructive fashion using near infrared (NIR) spectroscopy. NIR has the capability to determine the difference between superficial and full thickness burn injuries. Methods : Sixteen burn patients admitted to an adult regional burn center were studied and evaluated with the NIR point and imaging devices. Non‐burned skin adjacent to the burn site was used as the control. NIR measurements were compared between superficial (8 wounds), full thickness (8 wounds) burn wounds and control sites. Results : NIR was able to easily detect an increase in oxyhemoglobin (68.3%, p < 0.05), oxygen saturation (4.8%, p < 0.05%) and total hemoglobin (91.3%, p < 0.05) which typically occurs with superficial burn injuries. Full thickness injuries experienced a substantial drop in oxyhemoglobin (88.8%, p < 0.05), oxygen saturation (79.1%, p < 0.05) and total hemoglobin (77.5%, p < 0.05) in comparison to control sites. Conclusions : These results confirm that NIR spectroscopy can successfully distinguish between superficial and full thickness burn injuries. The second phase of this study will involve determining the depth of indeterminant burn wounds and this preliminary data will also be presented. Acknowledgement: National Research Council of Canada

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
