Triagem diagnóstica da doença pulmonar obstrutiva crónica

Spirometry is the accepted method for COPD diagnosis, a disease with high social costs. For certain professions, especially the ones that involve physical strength, the risk of COPD can be evaluated trough spirometry. In this work, using a data collection, it was evaluated the type of disease (obstructive and/or restrictive). The study shows that the forced expiratory volume in the 4th second should be valued instead of using the forced vital capacity, and a new indicator was introduced, which indicates the type of flow.
