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.

The Role of Fractional Exhaled Nitric Oxide in Asthma Management

Otolaryngologic Clinics of North America, 2014
Measuring fractional exhaled nitric oxide (FeNO) is a relatively new option for assessing allergic inflammation in the lungs. Clinical management of asthma is challenging, and measuring exhaled nitric oxide can provide another type of data to assist in meeting this challenge.

Fractional exhaled nitric oxide in pulmonary hypertension

4.3 Pulmonary Circulation and Pulmonary Vascular Diseases, 2016
Introduction: Decreased nitric oxide (NO) availability is implicated in the pathogenesis of pulmonary arterial hypertension (PAH). Prior studies found low fractional exhaled NO (FeNO) in idiopathic PAH (IPAH) and scleroderma-related PAH (SSc-PAH) patients. Comparison among different forms of PH has not been reported. Aims: Compare FeNO levels among

Relationship between fractional exhaled nitric oxide and nasal nitric oxide in airways disease

Annals of Allergy, Asthma & Immunology, 2010
Invasive techniques show evidence of a unified allergic airway. Nitric oxide is measured noninvasively from the lungs (fractional exhaled nitric oxide [FeNO]) and nose (nasal nitric oxide [nNO]).To investigate the relationship between FeNO and nNO in different airway conditions.A total of 227 participants were assessed: 41 healthy volunteers (HVs), 33 ...

Fractional Exhaled Nitric Oxide: Indications and Interpretation

2014
Exhaled nitric oxide (NO) is a marker for eosinophilic airway inflammation. The correlations between fraction of exhaled NO (FENO) and eosinophils in blood, sputum, bronchoalveolar lavage, and mucosal biopsies of the airway have been well studied. A quantitative, noninvasive, and simple methodology has been developed to determine how best to assess ...

Fraction of Exhaled Nitric Oxide in Patients With Acute Eosinophilic Pneumonia

Chest, 2012
Acute eosinophilic pneumonia (AEP) is an idiopathic disease characterized by pulmonary eosinophilia. Because the fraction of exhaled nitric oxide (Feno) is a surrogate of eosinophilic inflammation, we evaluated the levels, changed treatments, and the diagnostic role of Feno in patients with AEP.Between June 2010 and March 2011, we prospectively ...

Fractional exhaled nitric oxide in respiratory diseases

Perioperative Precision Medicine
Fractional exhaled nitric oxide (FeNO) is a simple, sensitive and non-invasive marker that can monitor eosinophilic airway inflammation. Its levels are influenced by height, weight, gender, ethnicity and smoking status. FeNO was first introduced as a biomarker to assist in asthma detection, and now plays an important auxiliary role in its diagnosis ...
