Is there a workout to help increase lung capacity?

Anonymous
I have CF and I joined a gym a little over a year ago and I've kicked it up the past 8 months and I'm in the best shape of my life but my endurance is still very limited and I gave up on it cause my lungs just kept giving up on me. But I have started running in the treadmill and I was bad, better than I was in the mile in gym class but still bad. I tried to run the mile in under 10:00 and I had 0.86 done with 43 seconds left, I turned it up high and I couldn't breath at all, I started to choke a little but I kept going and almost got it, when time expired I had ran 0.96 miles and I was very mad and disappointed in myself. Yesterday I tried to run half a mile in 5:00 and I got 0.53 in that time. I found I can force run a max of 45 seconds after I'm completely out of air before I collapse. Is there a workout that can increase my lung capacity?
