Hi all, I am new to this site, not sure if I am posting in the right place, I think I may need a bit of support for the future and you all seem like a friendly bunch. My mum has pulmonary fibrosis she has level 2 oxygen when resting for half the day and her sats are low 90's, she has level 2 overnight also and sleeps fine, but as soon as she stands up her sats drop to the 70's and she is struggling to walk, so for walking to the bathroom she is on level 8 oxygen, I am worried now that as she gets worse the oxygen wont be enough for her. Am I right in thinking that at home level 8 is the highest it can go, seems such a shame that when she is sitting she is fine, just when she is on the move she is bad. Also I am not sure if its panic attacks because she doesnt present as being struggling with her breathing like she isnt tugging a lot, like you see some people who are really tugging, she isnt like that, she just shuffles slowly to the bathroom and thats as far as she goes now. If she has to go out we push her in a wheelchair but now the cold weather has come, she doesnt want to go out at all. So does anyone know the answer to my question about the level 8 oxygen going higher at home.
