I was diagnosed with asthma/copd last fall, currently on Advair 250/50 with a ProAir rescue inhaler. I become short of breath with, for me at least, minimal exertion, but I'm just not sure when I truly need to use my rescue inhaler. Do I just go by what my O2 is, or just when I feel short of breath, or wait more severe shortness of breath. Yes, I am pretty new to all this.
Thank you for your advice!!
