NObreath®: The Primary Care FeNO Monitor
FeNO testing with the Bedfont® NObreath®
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.
The NObreath® is a recommended FeNO device by NICE1
With NObreath®, FeNO is a simple, straight-forward test to perform.
A 12 second test in 4 easy steps.
The practice run
To ensure compliance, you need to exhale through the mouthpiece at a certain flow rate. Connect the mouthpiece to the NObreath® flo and perform a test blow. The ball in the flow indicator needs to be within the white band throughout the duration of the test.
The monitor is easy to operate with its icon-based touchscreen display. Power on the NObreath®, attach the mouthpiece and select the adult or child setting to initiate the test.
Deep breath in…
When prompted, take a deep breath in and exhale. Remember to keep the ball within the white band on the flow indicator. Continue to exhale until the purple status bar is filled and the NObreath® beeps.
The reading will display as a single value in parts per billion on the screen. In accordance to the NICE guidance2, a reading of >40pbb is considered a positive test providing an indication that airway inflammation is present.
It can be used on adults and children
With simple on-screen prompts, the NObreath® can be used on both adults and children
SIMPLE TO USE TOUCHSCREEN CONTROL
Easy to follow icon based menus on a high resolution screen
Get accurate FeNO readings instantly
Obtain readings quickly, saving precious minutes in appointments
Easy Visual Aid for patient compliance
Ensures correct usage to obtain the most accurate FeNO reading
Tried and tested in clinical practice for diagnosis and monitoring of patients with Asthma
NO TEST LIMITS IMPOSED ON THE DEVICE
Low cost of ownership meaning you won’t need to replace the device after a certain amount of tests
Mouthpiece can be used more than once
Unlike other devices, the mouthpiece can be used by the same person more than once
The device provides a single reading in ppb. Record FeNO readings as you would record someones Blood Pressure.
Frequently Asked Questions
The device is recommended to be serviced once every 12 months.
The device is covered with a two year limited manufacturer’s warranty.
Yes. NICE already recommend the NObreath® in the “Measuring fractional exhaled nitric oxide concentration in asthma” guidelines. Published 2nd April 2014.
Yes. The mouthpieces are single patient use only and can be used for a maximum of 3 tests.
No. It is not necessary for a FeNO monitor, in any case, to have PC software. The device provides a single reading in ppb (parts per billion)
