I keep being asked by various doctors and specialist if I have COPD but I cannot get an answer from my own GP.
My O2 at rest in an upright position can be 92/95% but when lying down drops to 80/85% and will drop below 80% with mild exercise very quickly. I do have Pulmonary fibrosis, Pluresy, Asthma and a Paralysed Diaphragm. In the winter months I can be gasping for breath with a 7 step stride to my car.
I also have Atrial Fribulation which was Diagnosed back in 1992 and Repository Failure in 2008 which meant a 32 day stay on ICU 12 days I was on an oscillator and the rest of the time on some other machines to help me breath though the traci they installed.
