Rationale: Current asthma guidelines recommend adjusting antiinflammatory treatment on the basis of the results of lung function tests and symptom assessment, neither of which are closely associated with airway inflammation. Objectives: We tested the hypothesis that titrating corticosteroid dose using the concentration of exhaled nitric oxide in exhaled breath (FENO) results in fewer asthma exacerbations...

Controlled studies have shown that monitoring of the exhaled nitric oxide fraction (FeNO) improves asthma management. However, the studies seldom consider the full range of patients seen in clinical practise. In the present study, the ability of FeNO to reflect asthma control over time is investigated in a regular clinical setting, and meaningful FeNO cut-off points and changes are identified. Answers...

In medicine, exhaled nitric oxide (eNO) can be measured in a breath test for asthma which is characterized by airway inflammation. Nitric oxide (NO) is a gaseous molecule produced by certain cell types in an inflammatory response. Exhaled NO (also referred to as FENO) is a promising biomarker as a guide to therapy in adults and children with asthma. The breath test has recently become available in...

Doctors have been using fractional exhaled nitric oxide (FeNO) measurements to indicate airway inflammation and aid in asthma diagnosis for some time, leading many to believe that these measurements could play a role in actually diagnosing the problem. As it turns out, this noninvasive, inflammatory marker may not only send up a red flag for a positive diagnosis but also aid in confirming a negative...

Exhaled nitric oxide (eNO) is a noninvasive test that measures airway provides information about the asthmatic state consistent with information from other markers of inflammation. It is a noninvasive technique that could be used in decisional management of children with asthma. Asthma control is monitored by means of symptoms using pulmonary function tests, particularly FEV1 and FEV1/forced vital...

International guidelines recommend a range of clinical tests to confirm the diagnosis of asthma. These focus largely on identifying variable airflow obstruction and responses to bronchodilator or corticosteroid. More recently, exhaled nitric oxide (FENO) measurements and induced sputum analysis to assess airway inflammation have been highlighted. However, to date, no systematic comparisons to confirm...

One of the leading experts in asthma management devices discusses asthma and its implications. Asthma Overview Asthma is a chronic disease characterized by inflammation of the airways caused by allergens and other triggers. When airways are inflamed, the inner walls of the airways swell making them irregular. This causes the flow of air to become turbulent. The events that lead to obstruction of airflow...
