Pulmonary function test:
A lung function test determines to what extent the lungs and airways are fully functional. Diseases such as asthma, COPD (chronic obstructive bronchitis (smoking), emphysema, etc.) can be detected at an early stage.
Spirometry is used for health problems such as coughing, shortness of breath, sputum, and long-term cigarette consumption, as well as for aptitude tests in sports and occupational medicine.
It is a forced breathing test with which different lung volumes and air flow velocities are measured and thus provides information about the lung function.
