This is my first post anywhere, my mum has end stage copd she’s been on home oxygen for a year now she’s now on it 24hrs a day and goes on a mask over night and a couple of hours in the afternoon. She’s seems to just get worse and worse, she’s at a point now that she can’t do very much for herself and if she does her oxygen levels drop dramatically for example last night she walked upstairs aprox 12 steps and she did it slow even took a break, once we got to her bedroom merely another 5 or so steps her oxygen was at 76 her Heart rate was 110 lips purple. According to her this happens every time. I don’t really no what I’m asking but surely her body can’t keep coping with this? Honestly I feel I’m on tender hooks all the time. Anyone have experience with this. Thanks
