Asthma and Exhaled Nitric Oxide Level Measurement FeNO Test
In the past, patients with various bronchial diseases such as asthma had lung function tests (Spirometry) to assess bronchial stenosis and lung expansion. The mechanism of asthma is mainly caused by bronchial inflammation. Therefore, if we cannot control bronchial inflammation, lung function will decrease. One day, when the disease flares up, we may have to go to the hospital for treatment with an inhaler.
FeNO Test (Fractional exhaled Nitric Oxide) or measurement of nitric oxide levels in exhaled breath
Currently, there is a method to test for respiratory inflammation called the FeNO Test (Fractional exhaled Nitric Oxide) or the measurement of nitric oxide levels in exhaled breath. The inflammation values are measured as nitric oxide levels, which indicate respiratory inflammation in asthmatic patients. Therefore, it is suitable for use in monitoring and treating asthmatic patients.
For patients with asthma whose symptoms cannot be controlled, biologic drug treatment will be considered. Currently, there is medical คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย research that can apply this treatment to treat patients with chronic cough who do not have dangerous diseases (no alarming signs), which can predict the response to inhaled steroids.
FeNO Test is suitable for screening which patient groups?
1. Patients with chronic cough
2. Patients with asthma
3. Patients with severe asthma whose symptoms cannot be controlled to consider the use of biomolecule drugs.
Who is suitable for the FeNO Test?
1. Patients with chronic cough
2. Patients suspected of having asthma
Preparation before coming for FeNO Test
- Avoid smoking, drinking tea, coffee or caffeinated beverages for at least 1 hour.
- Avoid drinking alcohol 24 hours before the test.
- If you have a respiratory infection, you must be fully recovered before coming for a checkup.
- Avoid foods that contain nitrates, such as broccoli, kale, lettuce, celery, radishes, and smoked or pickled foods, for 3 hours before the test.
- Avoid strenuous exercise, pulmonary function tests, or bronchial stimulation tests for 1 hour prior to the FeNO test.
- If a pulmonary function test is scheduled on the same day, the FeNO test should be performed first.
