Abstract:Asthma affects the respiratory system and causes airway inflammation. The indication of asthma includes a triad of airway inflammation, hyperresponsiveness, and obstruction. Nitric Oxide (NO) is a gas that is exhaled and is a sign of airway inflammation. NO levels in the exhaled breath of patients with type 2 asthma are elevated, and fractional exhaled nitric oxide (FeNO) is an objective biomarker of airway inflammation. Measurements of FeNO are noninvasive, require minimal patient effort, and are easy to coll… Show more
