Obstructive lung disease. Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.
Thoracic outlet syndrome (TOS) is a condition caused by compression of nerves or blood vessels in the thoracic outlet, the area between the base of the neck and the armpit, including the front of the shoulders and chest. Vascular. This can be a compression of the artery and vein.
Second, the location of nerve compression or irrita- tion in the thoracic outlet is so central on the plexus and roots (the congenital bands) that the stimulating electrode cannot be placed proximal to the com- pression site. Thus, the current measured will not cross the site of nerve abnormality.
