Age 33. diagnosed with asthma / small airway disease. prescribed advair diskus (salmeterol and fluticasone) 250/50 and proair hfa. took a peak flow meter test and blew 350 l/min. is that bad? recommendations on how to improve?

More data: To give a better estimate, you will need your height, and you can look at this table: http://www.Sh.Lsuhsc.Edu/fammed/outpatientmanual/peakflowtables.Htm. To improve your capacity, exercise is good, particularly cardio. If you have a hard time running or similar, try swimming. It is a great exercise for people with asthma.

Asthma: Be sure you are living healthy life style, no smoking cigs. Or marijuana, eating correctly. Control weight, control alcohol. You may be allergic and this can cause asthma. Consider workup with allergist to see if allergy is a cause of your asthma.

Don't look: The peak flow rate is based on your height and sex and thus can't tell whether yours is bad or not. The more important point is how much has it changed from your pfr when you not have breathing problem. As suggested by dr pizzo, you should consult an allergist to help manage your problem. There is a chance that the atenolol may adversely impact your asthma. Fev-1 is superior to pfr.
