Random thought/question: do you think altitude has an impact on your asthma symptoms? I used to live at sea level but now live at about 3700 feet. I noticed previously in my old city, my o2 sat would always be 98-99%, but here more often then not it’s 95%. Maybe that’s why I’m noticing more symptoms (shortness of breath) at peak flows before that wouldn’t have bothered me. Example: I usually live at 450 when under perfect control, but used to get symptomatic at 340. Now sometimes I’m super uncomfortable at 380 and feel like a fish out of water at 300.
