1086 Evaluating a New Sleep Testing Device for Pediatric Patients: A Comparative Analysis of Type 2 HST vs In-lab PSG
Bibliographic record
Abstract
Abstract Introduction High-quality sleep is critical for children’s and adolescents’ development and health. Despite the high prevalence of sleep disorders in this population, few polysomnography devices have tested specifically for pediatric use. We evaluated the Dormotech device, a novel sleep monitoring system designed for both clinical and home-based sleep studies, against gold standard polysomnographic equipment. Methods Twenty-six children (mean age = 11.0 years, 50% female, mean body mass index 26.0 kg/m2) underwent simultaneous sleep studies with the novel device and gold-standard polysomnography in a sleep clinic. Data were manually scored following recommended guidelines. The primary outcome was apnea-hypopnea index (AHI) and its corresponding severity classification level (i.e. normal, mild, moderate, severe). Secondary endpoints included other standard polysomnography (PSG) parameters. Results The mean AHI measured by the novel device was 5.6 ± 15.3 events/h (mean ± standard deviation) while it was 5.2 ± 13.8 events/h from the gold standard PSG (p = 0.95, t-test). AHI severity classification showed excellent inter-test agreement (Cohen’s kappa = 0.87). Secondary endpoints demonstrated high correlation between devices, with no statistically significant differences in simultaneously recorded sleep measurements. No adverse safety events were reported. Conclusion The novel device provides sleep study data comparable to conventional polysomnography in pediatric patients, offering clinically identical test interpretation in nearly all cases. Its design enables flexible usage in both clinical and home settings in this population, improving accessibility of sleep disorder diagnostics. These results, combined with previous adult studies, suggest the device’s substantial equivalence to established, gold-standard PSG systems in usability, efficacy, and safety for a wide population of patients.

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.
