NObreath® FeNO Monitor (new model)

(includes 50 Mouthpieces FREE)

Fractional exhaled Nitric Oxide (FeNO) monitoring



Watch video !

A fractional exhaled nitric oxide (FeNO) breath testing monitor to measure airway inflammation and improve asthma management.
The NObreath® has been recommended by NICE to measure FeNO and aid in diagnosing asthma, in adults and children, as well as monitoring and managing asthma symptoms of patients.

Why is it important ?

Airway inflammation is a central process in asthma and other lung diseases1. Being able to detect eosinophilic airway inflammation and monitor a patient’s response to treatment is regarded as a gold standard in the management of respiratory diseases. It is becoming increasingly recognised that the measurement of FeNO in particular constitutes a novel way to monitor separate aspects of diseases. These include asthma, COPD and interstitial lung diseases that are not assessed by other means, such as lung function2. Nitric oxide measurement is not intended as a stand-alone method for diagnosis and should be used in conjunction with other evaluation methods and tests3. Using FeNO measurements to evaluate airway inflammation in asthma represents a significant advance in respiratory medicine4, but until now it has been an expensive test to deliver in every day practice.

Benefits to the user

The test is non-invasive, quick and easy to perform.
The measurement shows the patient’s response to treatment, enabling the correct prescription of medication and shows patient compliance.
The test also aids in identifying patients who do/do not require ongoing treatment
It is shown to be superior to the majority of conventional tests of lung function, such as peak flow recording and spirometry.
Airway Inflammation Monitoring
Measuring ENO with NObreath ENO Tester allows consistent, non-invasive measurement of expired breath nitric oxide (NO).
This can be used as a marker for airway inflammation and on-going monitoring of treatment.
