Bedfont NObreath v2 feNO Monitor

Cost-effective and non-invasive FeNO monitoring for the detection of airway inflammation, aiding healthcare professionals in making better clinical decisions.
 
Made in the UK, The Bedfont® NObreath® is a highly accurate, simple to use handheld monitor that facilitates the measurement of Fractional exhaled Nitric Oxide (FeNO) in the breath.

Using proven technology with over 10 years of clinical use, the monitor is designed to detect eosinophilic airway inflammation which allows healthcare professionals to make better, more informed clinical decisions for patients displaying symptoms of airway inflammation and provide the appropriate treatment and ongoing care. The test is simple to perform, non-invasive and requires very little respiratory effort making it suitable for use on children as well as adults.

The NObreath is ergonomically designed and is built using proven technology with over 10 years of clinical use. The device is easy to handle, lightweight and portable and made with Steritouch anti-bacterial coating for infection control. 

It is powered by an internal battery and comes with a USB charging docking station that also allows for PC-connectivity and comes with free FeNO chart software (COMING SOON).
 
 
 
Benefits of using FeNO
 
  • FeNO measurement is recommended as an option 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 do/do not require ongoing treatment.4
     
  • Shown to be superior to the majority of conventional tests of lung function, such as peak flow recording and spirometry.3
 
 
 
Asthma and FeNO testing explained.
 
Currently, asthma diagnosis in clinical practice lacks a gold standard.1 Whilst Spirometry and provocation testing methods are widely used in asthma assessments, these tests only really show a partial picture as they are indirectly associated with airway inflammation.2 Spirometry and peak flow measurement also rely heavily on patient compliance and the need for a good quality spirometry test.
 
Results from spirometry and peak flow tests can effectively show that a patient has an obstruction, however conditions such as COPD or chronic cough may present symptoms that are similar to that found in asthma.5 Consequently this could lead to patients either being mis-diagnosed or not receiving the right treatment for the disease.6

In an asthmatic person, the bronchial tubes in the airways become inflamed. Nitric Oxide in the bronchial tubes is produced at a higher than normal concentration. This is exhaled on the breath and can be measured using a Fractional exhaled Nitric Oxide (FeNO) monitor. A FeNO test is simple to perform and requires very little respiratory effort by the patient. Results are displayed as a single value in ppb (parts per billion).7,8

The measurement of FeNO can be used as a non-invasive biomarker of airway inflammation in asthma sufferers. A positive FeNO reading in conjunction with spirometry and peak flow tests can help confirm a diagnosis of asthma in a patient and/or support ongoing treatment for the disease.8
