Is it necessary to treat all asthmatic children with raised levels of exhaled nitric oxide? Treating the patient or the data

Certain doubts were raised about the usefulness of the FENO, as opposed to the traditional methods of asthma control with regard to the therapeutic management of clinically controlled patients who are not receiving treatment and who have high FENO values. It would appear unwise to recommend the systematic treatment of patients with high FENO values, when measured during a routine check-up, in cases of asthma with an allergic component and are asymptomatic or in a phase of asthma under good control.
