[Comparison of asthma score and peak flow rate (PEF) monitoring].

We have now two markers, peak flow rate(PEF) and asthma score, which reflect symptoms of asthmatics. We estimated which marker reflect the change of symptom of asthma more rapidly or exactly. With using the point of 20% down from best PEF, we could get rapid information but not so exact one. But the point of 30% down brought more exact information but not rapid one. So, both PEF and asthma score are useful in monitoring the condition of asthmatics. Under reducing the amount of inhaled steroid, it seemed to be more useful to use monitoring of PEF than asthma score, because PEF showed the change one month before asthma score showed the attacks.
