Convert SaO2 to 1 Hz by per-second median; accept 50-100%, remove isolated <=2-second outliers more than 4 points from a centered 9-second median, interpolate only bounded internal gaps <=30 seconds, apply a centered 9-second median, and exclude all remaining missing seconds. Treat N1/N2/N3/R as sleep and W as wake. Report percentages. ISRUC: SaO2=oxygen saturation; X5=snore; X6/DC3=airflow; X7/X8=abdominal effort."
