Lungefunktionsundersøgelse

Lungefunktionsundersøgelse, also known as spirometry, is a non-invasive medical test used to measure how well your lungs work. It is a key diagnostic tool for a variety of respiratory conditions. The test involves breathing into a device called a spirometer, which records the amount of air you inhale and exhale, and the speed at which you do so.

During the procedure, you will be asked to take a deep breath and then exhale as forcefully and quickly as possible into the mouthpiece of the spirometer. The spirometer then measures several key parameters, including Forced Vital Capacity (FVC), which is the total amount of air you can forcibly exhale after taking a deep breath, and Forced Expiratory Volume in one second (FEV1), which is the amount of air you can exhale in the first second of exhalation. The ratio of FEV1 to FVC (FEV1/FVC) is also an important indicator.

Lungefunktionsundersøgelse is commonly used to diagnose and monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD), emphysema, and bronchitis. It can also be used to assess lung function before surgery or to evaluate the effectiveness of respiratory treatments. The results of the test are compared to predicted values based on your age, sex, height, and ethnicity to determine if your lung function is within the normal range. A healthcare professional will interpret the results to make a diagnosis and guide treatment decisions.
