Count days on which child received O2 for at least 12 hours per day, FiO2 > 21% (21% oxygen is considered room air and does not count as day of O2), prior to reaching 36 0/7 weeks gestational age or discharge home (whichever comes first).
Saturation levels: lower level 85% up to week 34, 88% thereafter – target level 90%-95%.
Enter 0 if O2 never required after leaving the delivery room.
Select Home O2 (item 102) if child discharged on O2.
