Thank you to everyone who responded to my post. I should of explained and introduced myself better yesterday evening. I have end stage emphysema or stage 4 as it is also known. My consultant is in the process of referring me to meet the transplant team here in Newcastle England. I've never really understood or bothered to find out what FEV1 19% so on is. So thank you for all the responses to my post. I will take a look at the YouTube one and hopefully will understand more by the time it's finished lol. I'm also new to computers , so bare with me . Thanks All.
