Quizplus · Accepted Answer

Many clinicians today use FENO to determine the eosinophilic response to corticosteroids,unmasking of otherwise unsuspected nonadherence to therapy,and routine monitoring.According to the ATS Clinical Practice Guidelines,a patient with a low FENO level of less than 25 parts per billion (ppb)is considered less likely to respond to corticosteroids than one with a high FENO level of > 50 ppb who is symptomatic.An intermediate is considered to be between 25-50 ppb.
