Fraction of Nitric Oxide in Exhaled Breath

Clinics in Chest Medicine
Nitric oxide (NO) is an odorless gaseous molecule important for biological functions including regulation of vasodilation, smooth muscle relaxation, neurotransmission, platelet aggregation inhibition, and airway epithelial barrier function. It was first discovered in exhaled breath by Gustafsson and colleagues in 1991.

An official JRS statement: The principles of fractional exhaled nitric oxide (FeNO) measurement and interpretation of the results in clinical practice.

Respiratory Investigation, 2020
Nitric oxide (NO) is produced in the body and has been shown to have diverse actions in the abundance of research that has been performed on it since the 1970s, leading to Furchgott, Murad, and Ignarro receiving the Nobel Prize in Physiology or Medicine ...

Fractional exhaled nitric oxide measurement with a handheld device

Journal of Breath Research, 2011
A sensing system for fractional exhaled nitric oxide (FeNO) measurement is presented, which is characterized by a compact setup and a cost potential to be made available for the patient at home. The sensing is based on the work function measurement of a phthalocyanine-type sensing material, which is shown to be sufficiently sensitive for NO(2) in the ...

Fractional exhaled nitric oxide and induced sputum

Paediatric Respiratory Reviews, 2007
Conventional asthma management aimed at controlling the underlying airway inflammation is classically based on symptoms and lung function. More recently, various non invasive markers of airway inflammation have become available. The ideal measurement method should be safe, non-invasive, easy to perform, reproducible and accurate.

Fractional Exhaled Nitric Oxide in Clinical Trials: An Overview

2013
Designing clinical trials in asthma it is crucial to find the perfect primary endpoint for showing bioequivalence, especially when the investigational medicinal product is not a bronchodilator, but a substance, which suppresses the inflammatory process, e.g. inhalative corticosteroids (ICS).

The Use of Fraction of Exhaled Nitric Oxide in Pulmonary Practice

Chest, 2008
The measurement of the fractional concentration of exhaled nitric oxide (FeNO) is a convenient, noninvasive, point-of-service office test for airway inflammation. The first half of this practice management review presents the methodological, interpretative, and clinical applications of FeNO.
