Accuracy of detecting changes in auditory heart rate in a simulated operating room environment*
Bibliographic record
Abstract
The threshold for the identification of changes in heart rate and the accuracy in estimating heart rate were compared between 20 anaesthetists and 20 non-anaesthetists in a simulated operating theatre, both with and without distraction tasks. Typical operating theatre distractions were simulated by requiring anaesthetists and non-anaesthetists to perform secondary tasks. There were no differences found between the groups in identification of heart rate changes. The distraction tasks reduced performance in both groups (to a greater extent in the anaesthetists group). A change of > 10 beats per minute was required for 80% of the changes to be detected. An upward heart rate change was more easily detected than a reduction. Anaesthetists were found to be marginally better at estimating the heart rate change from an auditory tone alone. However, the study did not confirm that anaesthetists have a superior ability to detect changes in heart rate than non-anaesthetists.

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.
