The NIOX MINO addresses several drawbacks found in generally accepted chemiluminescence analyzers, used to monitor asthma patients' nitric oxide (NO) levels. The hand-held device is attractive and encourages the use of NO measurements. The measurement is done by a non-invasive, quick and repeatable method. NIOX MINO is to be used by medical professionals in clinics and in primary care for monitoring adult and pediatric patients. Ultimately, it could also be used by a patient at home for monitoring of their NO status.
