We r in the process of weaning our ex 24 weeker off oxygen she's off during the day and has 1/4L at night (if we can keep the cannula on her,it's a battle) and last night our dme company dropped off a over night pox and we trialed her on room air, to my knowledge she hasn't gone below 89 --I wasn't up all night but I didn't sleep as well so I kept looking, she's usually btwn 90-93 in a deep sleep and heart rate 85-90s. We get results I think next week. But how low is too low for room air sleeping? For an adult usually 88 % is on the lower end but unsure for a infant. She's 8 1/2 months adjusted age and 12 months actual. I just feel so bad holding her down to tape the oxygen on and she screams and pulls it off. But I don't wana get it discontinued if she needs it. Anyone have similar experiences?
