Spirometry is a simple non-invasive method to assess respiratory function and lung capacity
by comparison to the average respiratory function of an individual with the same race,
weight and age (theoretical values).
This spirometry is performed systematically to the candidates in order to assess their
general condition and periodically during the flight medical examination. This exam can
also be requested for the diagnosis of some respiratory diseases, the assessment of
their impact or for prevention.
The different spirometry measurements can be useful to determine whether the
candidate has a lung disease and to specify its category. Thus, the spirometry
can show an obstructive syndrome such us a chronic obstructive pulmonary disease
(COPD) or an asthma or a disorder suggesting a restrictive syndrom like in case
of lung surgery or chest deformity.
