Origin of Term “Buffalo Chest”: originates from the American bison (buffalo), one of the few mammals which normally has bilaterally-interconnected pleural spaces
This anatomic feature of the buffalo made it easier for Great Plains American Indians to kill the buffalo with a single arrow shot to the thorax (which resulted in bilateral pneumothorax and rapid death of the animal)
Increased Risk of Bilateral Pneumothorax (see Pneumothorax)
