## Indications for use
Vivatmo pro-S nitric oxide test is a portable, non-invasive device to measure fractional exhaled nitric oxide (FeNO) in human breath. FeNO is increased in some airway inflammatory processes, such as asthma, and often decreases in response to anti-inflammatory treatment. Measurement of FeNO by Vivatmo pro-S is a method to measure the decrease in FeNO concentration in asthma patients that often occurs after treatment with anti-inflammatory pharmacological therapy as an indication of therapeutic effect in patients with elevated FeNO levels. FeNO measurements are to be used as an adjunct to established clinical assessments. Vivatmo pro-S is suitable for children, approximately 7-17 years, and adults 18 years and older. Testing using the Vivatmo pro-S should only be done in a point-of-care healthcare setting under professional supervision. Vivatmo pro-S should not be used in critical care, emergency care or in anesthesiology.
