Premise
COPD is a serious respiratory disease, caused by the chronic and pathological narrowing of the bronchial airways and a series of consequent breathing difficulties, especially during the exhalation phase.
COPD stands for Chronic Obstructive Pulmonary Disease:
- BronchoPneumopathy, because the suffering is borne by the bronchi and lungs;
- Chronic, because COPD has a course which, although slow, is progressive and unstoppable;
- Obstructive, because the cause of breathing difficulties is an abnormal narrowing of the airways.
