Nocturnal Oximetry Reference Values in Healthy Term Infants Aged 1-6 Months
Bibliographic record
Abstract
Although nocturnal oximetry has been used for OSAS management in resource-limited settings, little evidence is available regarding reference values in infancy. Our aim was to summarize reference values for oximetry parameters in healthy infants aged 1-6 months. Methods: Prospectively collected oximetry data from full-term infants without history of apnea, upper airway obstruction (UAO), craniofacial abnormalities, neuromuscular disorders, genetic syndromes or lung disease were analyzed. Summary statistics of oxyhemoglobin desaturation (≥3%) index (ODI3),baseline SpO2, and cumulative nocturnal hypoxemia score ([%recording time-%RT with SpO2 90–94%]X1 + [%RT with SpO2 85–89%]X2 + [%RT with SpO2 80–84%]X3 + [%RT with SpO2 ≤79%]X4) as well as frequency of abnormal McGill Oximetry Score (MOS>1) were calculated. Results: Data from 51 infants (median age 2.8 months; range 1-6.6) were analyzed (Table). ODI3 decreased linearly with age (P=.01) and MOS was abnormal in an appreciable proportion of participants. Conclusions: In the first 1-6 months of life, nocturnal baseline SpO2 is above 95% and-in contrast to older children-ODI3 decreases with age while MOS is frequently abnormal in the absence of UAO.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
