Hi, my name is Christina. I was diagnosed with COPD six months ago after a pulmonary breathing test. I was diagnosed with mild emphasema with a 76%. lung capacity, my doctor continues to tell me that it's not that bad. But yet, in the last 6 months, it seems like it's gotten worse. Its getting harder to breathe, getting short of breath faster than normal. More coughing with a lot mote mucas. I had a lung scan, June 9th, and it also showed mild emphysema only, but yet had a lung scan 2 days ago at the hospital and the results showed mild emphysema, and mosaic perfusion pattern, bibasilar atelectasis, and a 3mm nodule. I've been in the hospital twice in 1 week, because my oxygen levels are dropping into the 80s. Is this normal for what my doctor considers Mild emphysema
