Thank you for info!☺️

I am not on 24/7 but at night and while amatory. I'm not a Dr either, but my Dr explained it to me as your breathing gets shallower at night and you might not get a dose of O2 when you need it. Although he ok'ed it for a night or two. Mine is a G5 and has an alarm on it, if it doesn't sense a breath you get an alarm. It was a learning experience. 4 times a night it woke me up.

FYI. For longer trips you can call your O2 supplier and have them send a unit to the hotel before you get there. That way you have a continuous unit in the room. It is part of their service.
Hope that helps you some. Breathe Ez........
