What is it?

A fractional exhaled nitric oxide (FE_NO) testing monitor.

Why is it important?

Airway inflammation is a central process in asthma and other lung diseases. Being able to measure this inflammation and monitor the patient’s reaction to medication is regarded as gold standard in the management of respiratory diseases. It is 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 function. The FENO measurement to evaluate airway inflammation in asthma represents a significant advance in respiratory medicine, but until now this has been an expensive test to deliver in everyday 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.

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.
