Can a pulse oxygen saturation of 95% to 96% help predict further vital sign destabilization in school-aged children?
Bibliographic record
Abstract
To determine whether a peripheral capillary oxygen saturation (SpO2) of 95% to 96% should be considered "nonurgent" in school-aged children, as suggested by the Canadian Emergency Department Triage and Acuity Scale.School-aged children (6-12 years old) with a normal body temperature (36.5-37.4°C) who visited our department between September, 2014 and August, 2015 (n = 4556) were divided into 4 groups based on SpO2: group A: 99% to 100%; group B: 97% to 98%; group C: 95% to 96%; and group D: ≤94%. The heart rate (HR), respiratory rate (RR), and hospitalization rate were compared among the groups, and also between children with SpO2 95% to 96% and matched controls with SpO2 ≥97% (n = 280 each).Among 4556 eligible patients, groups A, B, C, and D comprised 2700 patients (59.3%), 1534 patients (33.6%), 280 patients (6.2%), and 42 patients (0.9%), respectively. The median (interquartile range [IQR]) RR significantly increased with decreasing SpO2 (23 [20-25], 24 [20-26], 24 [23-30], and 30 [24-40] breaths/min in groups A-D, respectively; P < .001). Similarly, the median (IQR) HR significantly increased with decreasing SpO2 (93 [83-104], 98 [87-110], 107 [93-119], and 121 [109-137] bpm, groups A-D, respectively; P < .001). Group D had the highest annual hospital admission rate (18 cases/42 patients, 42.9%). Further, the HR and RR differed significantly between the cases (107 [93-119] bpm; 24 [23-30] breaths/min) and controls (96 [86-106] bpm; 24 [20-28] breaths/min, respectively) (P < .001 and P = .02, respectively).An SpO2 of 95% to 96% among school-aged children should not be considered "nonurgent," but rather a significant clinical situation that requires early review of HR and RR. Prompt interventions among this group of children will help prevent further destabilization of vital signs, which will, in turn, contribute to decreased healthcare costs.

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.
