FAQ
1. What is FeNO and why is it important in asthma diagnosis?
FeNO (Fractional exhaled Nitric Oxide) is a biomarker for airway inflammation. Elevated FeNO levels can indicate eosinophilic inflammation, commonly found in asthma. Measuring FeNO helps confirm diagnosis and guide appropriate treatment.
2. How does NIOX VERO work?
NIOX VERO is a portable, non-invasive device that measures FeNO levels in a patient’s breath in just one minute. It provides immediate, quantitative results to support clinical decisions in asthma management.
3. Is the FeNO test safe and comfortable for patients?
Yes. The test is completely safe, non-invasive, and requires only a slow, steady exhalation through the mouthpiece. It’s suitable for both adults and children aged 4 and up.
4. Can NIOX VERO be used in primary care settings or only by specialists?
NIOX VERO is designed for use in both primary care and specialist clinics. Its ease of use and portability make it ideal for GPs, paediatricians, allergists, pulmonologists, and asthma educators.
5. How often should FeNO be measured in asthma patients?
FeNO levels can be measured during initial diagnosis, at follow-up appointments, when considering changes in corticosteroid therapy, or when asthma control deteriorates.
6. What do the FeNO readings mean?
Low FeNO (<25 ppb adults / <20 ppb children): Low likelihood of eosinophilic inflammation
Intermediate FeNO (25–50 ppb / 20–35 ppb): Possible inflammation
High FeNO (>50 ppb / >35 ppb): Strong indicator of eosinophilic inflammation, likely to respond to corticosteroids
Always interpret in context with clinical findings.
7. Does FeNO testing replace spirometry or other lung function tests?
No. FeNO is complementary to spirometry. While spirometry measures lung function, FeNO provides insight into airway inflammation, helping to identify steroid-responsive asthma.
