From a single breath, the NObreath® can provide an indication whether there is inflammation present in the airways. 

NICE now recommends FeNO testing in latest asthma guidelines to help diagnose and manage asthma in adults and children.1

About the NObreath® FeNO Monitor

The Bedfont® NObreath® is a simple to use handheld monitor that measures Fractional exhaled Nitric Oxide (FeNO) in the breath. The device has been designed for use within the primary care setting and can be used on children as well as adults.

An adult patient blows into the NObreath® for 12 seconds giving an instant result for FeNO in ppb (parts per billion).  The higher the FeNO reading the greater the inflammation in the airways.


Benefits of FeNO testing

  • FeNO measurement is recommended to help diagnose asthma in adults and children1
  • Taking a measurement is non-invasive, quick and easy to perform3
  • Provides a complementary tool to other ways of assessing airways disease, including asthma.
  • Shows patient’s response to treatment, enabling the correct prescription of medication.
  • Aids in identifying patients who may require a change is dose of prescribed medication.4
  • Shown to be superior to the majority of conventional tests of lung function, such as peak flow recording and spirometry.3
