Atelectasis is composed of 78% nitrogen and 21% oxygen. Since oxygen is exchanged at the alveoli-capillary membrane, nitrogen is a major component for the alveoli's state of inflation. If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood, reducing the volume of the alveoli, resulting in a form of alveolar collapse known as absorption atelectasis. It is usually associated with accumulation of blood, fluid, or air within the pleural cavity, which mechanically collapses the lung. This is a frequent occurrence with pleural effusion, caused by congestive heart failure (CHF).
The Blue Humans The Blue Humans The Blue Humans is the name used by experimental guitarist Rudolph Grey for the improvised performances he leads with a variety of other musicians. Grey first came to notice in the late-1970s New York City post punk and art scene which also produced Sonic Youth and Swans, and played in the influential no wave band Mars. Since then, he has released solo material as well as several Blue Humans records, the latter mostly live recordings. Blue Humans members and collaborators have included Tom Surgal, Arthur Doyle, Beaver Harris, Alan Licht, Charles Gayle, and Thurston Moore. Blue Humans
