Asthma is characterized by chronic inflammation of the bronchial mucosa manifested by bronchial obstruction in response to exposure to allergens. Patients with asthma often have symptoms of shortness of breath.

Bronchial asthma is a chronic respiratory disease with a high prevalence, especially in children. There are many methods applied in the diagnosis of bronchial asthma today, including the technique of measuring NO gas concentration.

Nitric oxide (NO) has been known as a gas in the environment polluted by vehicle exhaust and cigarette smoke. However, recently NO in the breath has become more known thanks to its association with the FeNO test - a highly reliable test.

Pulmonary function testing, also known as spirometry, is a test used to screen, diagnose, and monitor respiratory diseases such as asthma, chronic obstructive pulmonary disease, and restrictive lung disease.

Pulmonary function tests are a way to measure how well you breathe in and out of your lungs, and how much oxygen is getting into your body. The most common respiratory function tests are spirometry, diffusion studies, and plethysmography. So what do the respiratory function tests mean?

Asthma is a common condition in children. Children under 5 years of age with asthma are often difficult to diagnose and treat because the cause of the disease is difficult to determine and the symptoms are atypical.

FeNO measurement is a simple, rapid, non-invasive and highly reliable test. FeNO reflects certain inflammatory mechanisms (among many) of asthma that cannot be reflected by lung function.

Asthma is not a rare disease, it is considered to cause many inconveniences in life. To help control the disease better, many people have proactively used popular asthma management tools today.
