Aportaciones del óxido nítrico exhalado a los procedimientos abreviados de las pruebas de provocación bronquial

The abbreviated bronchial challenge test recommended by the ERS led to exaggerated bronchoconstriction in 30% of the patients studied. FENO measurements could possibly be used to identify patients at increased risk of exaggerated bronchoconstriction. The shortened challenge test can be performed safely in individuals with a FENO of <19.5 ppb.
