AWESOME COPD stuff!!! I did not even think about looking at the Quit smoking thing...LOL...I have already got my Mom blowing up balloons to get rid of extra CO2...And it's seems to be working...Ha ha ha....She is getting better each day anyway and now we have the balloon idea & we also got her a brand new oxygen concentrator today as well...I could not believe how excited we got over the daw gone thing because it's a pretty blue color and so quite & smells like new plastic....Ha ha ha...I added your site to my favs...Thanks again Peggy!! :)
