Emphysema is a lesion of the airways of the lungs in which the cavity of the alveoli changes shape and size, and their walls become thin and inelastic. The alveolar cavity collapses due to blockage of the bronchioles or decreased elasticity of the alveolar walls. Because of this, the patient cannot breathe fully. The walls of the alveoli become thin-walled or disappear altogether, resulting in the formation of many cavities of various sizes - alveolar emphysema. The lungs are filled with air, but it is poorly saturated with oxygen and carbon dioxide is poorly removed. The patient is unable to fully inhale air and his breathing becomes shallow. The alveoli may shrink to the size of a millet grain, called lobular emphysema. During this process, the blood begins to stagnate and areas of lung tissue die. The disease decompensates, increasingly worsening the functioning of the body. When it comes to development
