Hi Peg, I have done a little reseach into the Forced vital capacity, and basically as the muscles weaken in the diaphram and lungs it is difficult for air to be passed. You may notice that you are out of breath a lot more, sometimes just talking can make you out of breath. My mom was at 70% when dx Oct 087, when tested in July she was at 33%, she is going into hospital and I just know her breathing is much worse, so expecting it now maybe at about mid 20's. Breathing for her is almost a chore these days, and she cant even lie down anymore, she sleeps sitting up as she cannot use the bipap during the night, she also suffers clostraphobia, and so will only use the bipap when she knows someone is sitting with her, if she panics a bit she just waves her arms and I have to take it off, she also suffers panic attacks.
I think eventually it is the breathing that affects most people and ultimately causes death, so you should always ask for your pals fvc, I know our doctor never likes to give it to me! He knows Im on the internet constantly, although Ive learned more here than any doctor.
I did read that when it gets to early 30s it can signal end of life, I dont believe it too much, right now my mam is out with her friends for lunch which always includes a few glasses of Vino and a good gossip, her social life certainly hasnt been affected too much! Keep the spirits up guys. We might not be here for a long time but we can have a good time
