My mother-in-law is living with us at high altitude (6200 ft); she was prescribed oxygen to wear at night and during the day also. When she is not wearing it, she is dizzy and says she feels like she's going to fall. She also sleeps the majority of the daytime. My husband's brother lives at sea level, yet, for some reason, she does not want to go down there to live even though they have room for her. We just measured her O2 Sat and it is 85%. When she is on oxygen, it is 95%. She is very stubborn about wearing the oxygen during the day. Our dilemma is: should we send her to my husband's brother (where she will be uncomfortable, but where she will have air to breathe), or should we honor her wishes and let her live with us even though her oxygen is low up here. We have told her continuously that she needs to be on oxygen day and night, but she is very stubborn and will not wear the oxygen during the day. We are worried that NOT sending her to sea level will constitute elder abuse, even though she is of sound mind and is making a decision not to go. What would you do?
