Spirometry
Spirometry is a simple test used to diagnose and monitor lung diseases by measuring how much air a person can breathe out in one forced breath.
After the baseline spirometry, and only if there is clear evidence of an airflow limitation/obstruction, i.e., if the FEV1/FVC (forced expiratory volume in the first second/forced vital capacity) ratio is less than 70% or less than the 5th percentile of the distribution of values measured in the reference population, a bronchodilator test will be performed using standardised post-bronchodilator spirometry (200 µg salbutamol), in order to identify persistent airflow limitation/obstruction.
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Written informed consent for study participation.
Exclusion Criteria
* Any condition that makes it impossible to perform the bronchodilation, as described in the "Contraindications for bronchodilation" section of the Study Procedures Manual;
* Severe cognitive disability that may interfere with the person's capability to participate in the study.
