FeNOmätning

FeNO-mätning, also known as fractional exhaled nitric oxide measurement, is a tool used for diagnosing and monitoring respiratory conditions such as asthma. It involves measuring the amount of nitric oxide present in the exhaled breath of an individual.

Nitric oxide is a gas produced in the body, which is naturally present in higher concentrations in people with asthma compared to non-asthmatics. FeNO-mätning detects the level of this gas in the exhaled breath, providing an indication of the level of airway inflammation.

The measurement is typically performed by having the person exhale into a device, usually through a tube connected to a gas analyzer. The device then calculates the concentration of nitric oxide present in the breath, usually expressed as parts per billion (ppb).

FeNO-mätning is considered a sensitive indicator of airway inflammation and is used in the diagnosis of asthma and other respiratory conditions. It can be particularly useful for distinguishing between asthma and other conditions that may cause respiratory symptoms.

FeNO-mätning is becoming increasingly recognized as a valuable tool for managing and monitoring respiratory conditions. It is often used in conjunction with other diagnostic tools and measurements, and can provide valuable information to healthcare professionals when interpreting respiratory test results.

Research is ongoing to further develop and refine FeNO-mätning technology, as well as to explore its potential uses in other areas of healthcare. As a result, it is expected that FeNO-mätning will become an increasingly important tool in the diagnosis and management of respiratory conditions in the future.
