Lung Function Test: #2 FeNO
How does it work?
🫁Triggers and allergens leads to activation of immune system
🫁Causing inflammation in airways
🫁Inflammation causes Nitric Oxide to be released
🫁FeNO measures Nitric Oxide in airways
Exposure to certain stimulants causes the activation of your immune system. This triggers the body to produce Nitric Oxide to further tackle the inflammation. The level of Nitric Oxide in your airways is detected by FeNo- analysing the severity of your condition and airways.
