Pulmonary emphysema

Pulmonary emphysema is a serious disease. A rare form of respiratory failure caused by tobacco, in most cases. It is the elastic tissues of the pulmonary alveoli that are progressively destroyed.

Result: the pulmonary alveoli fail to inflate or empty normally. Breathing becomes more and more difficult.
The disease evolves with age. The problem is that one can be reached without knowing it and that the diagnosis is not always easy to ask.

Pulmonary emphysema is the destruction of the elastic wall of the alveoli, these small sacs which are at the end of our bronchi. The alveoli are the essential structures of our lungs. These small membranous sacs are gathered in clusters, surrounded by blood capillaries. This is where gas exchange takes place: oxygen and carbon dioxide. When we breathe, these pulmonary alveoli inflate with air, dilate; then they empty at expiration, retracting.

When the elasticity has disappeared, in case of emphysema, the cells thicken and stiffen. When they are inflated with air, they can no longer empty properly. Worse: the lung swells the more you try to clear the air. The ribcage does not work normally and can even slightly deform.
