You are correct about when yo use inhalers, and which ones.
In my case, I have no "evident" infection at this time, but asthma & bronchiectasis coexist in my lungs. For months I have been struggling with shortness of breath, chest tightness and rising heart rate at the simplest exertion (like putting laundry in the washer.) Nebs help, but being tethered to the machine repeatedly was not working well...So we are trying a different type of inhaler, with more long-acting meds, to get me back to being myself. As of today (#7 with no neb) - I am feeling better on the new med, even after a 3 day camping trip with 7 adults, 5 kids, 1 dog and a whole bunch of drop in visitors. I can't wait to see how I'll feel after a shower and some rest.
