These days it takes me two or more Albuterol puffs, 10 miles at 80rpm and 13 mph before my lungs are really working at their optimal level. Frustrating, but there it is.
What you are referring to is a peak flow meter.
Great tool with limitations.
Make sure you have a good professional diagnosis.
My buddy's "asthma" on rides, proved to be advanced 4 vessel obstruction and atypical angina.
He did much better after he got a "full metal jacket"
