NObreath FeNO breath monitor

Fractional exhaled Nitric Oxide (FeNO) monitoring

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.

Why NObreath®?

The monitor incorporates a colour touch screen.
The battery indicator shows you when how much battery you have left and when you need to change your NObreath® batteries.
Has adult and child compatibility profiles.
An internal pump and NO scrubber. 

NObreath® consumables

NObreath® mouthpiece

Specifically designed with the latest bacterial filtration to remove 99.9% of airborne bacteria from the patient's breath. These can be used up to 3 times per patient, dramatically reducing the cost of testing for FeNo.

NObreathFLO™

Eye level flow indicator makes keeping a constant flow during exhalation easy, even for young children. Using the NObreathFlo™ and mouthpieces provided allows the user to comply with ATS/ERS guidelines for FeNO testing.

Monitor cleaning wipes

Free from alcohol, ensuring the continued performance of your monitor. Pack contains 50 wipes.

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.
