FeNO Testing. Made Simple.
Made Affordable. Without Limitations.
Quick and accurate measurement of FeNO. Without the expensive consumables and running costs.
The Bedfont® NObreath® is a simple to use, battery-powered handheld monitor that measures Fractional exhaled Nitric Oxide (FeNO) in the breath. The device has been designed for use in almost any clinical setting and can be used to test children as well as adults.

An adult patient blows into the NObreath® for 12 seconds (children exhale for 10 seconds) giving an instant result for FeNO in ppb (parts per billion). The higher the FeNO reading the greater the inflammation in the airways.

A 12-second test in 4 easy steps.
1
The mouthpiece
The mouthpiece is supplied wrapped and is a long tube that connects to the front of the monitor. It contains a one-way valve and a viral bacterial filter reducing the risk of cross-infection between patients. A NObreath® mouthpiece can be used multiple times by the same patient reducing the cost per test.
2
Initiate test
The monitor is easy to operate with its icon-based touchscreen display. Power up the monitor from the button located at the top of the monitor. Monitor warm up time is ≤60 seconds. To initiate the test, simply select the adult or child setting and follow the prompts.
3
Deep breath in…
When prompted, take a deep breath in and exhale. Very little respiratory effort is required. In order to succesfully complete the test, the breath should be exhaled at a steady flow for the duration of test. Resistance in the mouthpiece and the on-screen incentive help achieve this.
4
Test complete!
A green tick will appear if it is a good quality test. The reading will display immediately afterwards as a single value in parts per billion on the screen. In accordance to the NICE guidance2, a reading of >50pbb is considered a positive test providing an indication that airway inflammation is present.
Free FeNO Chart PC Software Included
FeNOchart™ PC software comes free with the NObreath® monitor as standard. It allows for test results stored on the monitor to be downloaded via USB cable to any PC.
The software facilitates the electronic recording of FeNO test results with trending in order to easily track patient compliance to prescribed medication for better management of the condition.
A PDF report option allows for easy export and attachment to any patient record system in just a few clicks.

Frequently Asked Questions
What is FeNO and why is it important?
FeNO stands for fractional exhaled nitric oxide. Higher FeNO levels may indicate eosinophilic airway inflammation. Measuring FeNO can help assess inflammation, monitor response to inhaled corticosteroids and support treatment decisions to improve asthma control.
What is the NObreath®?
The NObreath® is a handheld FeNO device used to measure fractional exhaled nitric oxide, an indicator of eosinophilic airway inflammation. FeNO testing can support asthma diagnosis and ongoing management.
Who is the NObreath® for?
The device is suitable for GP surgeries, asthma review clinics, community diagnostic hubs, respiratory services and secondary care settings. It can be used with adults and children for asthma assessment and follow up.
How does the NObreath® test work?
The patient inhales and then exhales steadily into a disposable mouthpiece. The device provides on screen guidance to support a consistent breath sample. The FeNO level displays as a single numerical value in parts per billion.
Is the NObreath® suitable for children?
Yes. The device includes guided prompts that help children maintain a steady breath, making FeNO testing suitable for younger and older patients.
Is FeNO testing recommended in UK guidelines?
Yes. FeNO testing is recognised in UK asthma guidance. NICE NG245 includes FeNO as part of the diagnostic and monitoring pathway. The British Thoracic Society and Scottish Intercollegiate Guidelines Network also support the use of FeNO to help identify eosinophilic airway inflammation and guide treatment.
What do FeNO results mean?
Higher FeNO values may indicate eosinophilic airway inflammation and potential responsiveness to inhaled corticosteroids. Lower FeNO levels may indicate controlled inflammation. FeNO results should be interpreted alongside symptoms and clinical history.
How long does each test take?
A FeNO test typically takes less than one minute including instruction and breath sampling.
Are there consumables required for the NObreath®?
Yes. A single patient mouthpiece is used for hygiene and accurate measurement. Each mouthpiece includes a built in bacterial and viral filter.
What is the ongoing cost per test?
Only one single patient mouthpiece is required per testing session, and it can be reused multiple times during the same appointment with the same patient. This helps maintain low running costs. Around £3.70 per patient.
Can I store or transfer results from the NObreath®?
Yes. FeNOChart™ PC Software is included as standard. It allows clinicians to store results, compare historical data, review trends and generate PDF reports to support follow up and shared decision making. FeNOchart™ can be downloaded HERE
Does the NObreath® need to be serviced?
The device is recommended to be serviced once every 12 months.
Does the NObreath require calibration gas?
No. The device uses a stable electrochemical sensor and does not require calibration gas. This reduces ongoing maintenance and supports cost efficient operation.
What is the warranty on the NObreath®?
The device is covered with a 5 year limited manufacturer’s warranty.
