Origin: [NL. See Cyanic.]
Cyanosis is the appearance of a blue or purple coloration of the skin or mucous membranes due to the tissues near the skin surface being low on oxygen. The onset of cyanosis is 5.0 g/dL of deoxyhemoglobin. The bluish color is more readily apparent in those with high hemoglobin counts than it is with those with anemia. Also the bluer color is more difficult to detect on deeply pigmented skin. When signs of cyanosis first appear, such as on the lips or fingers, intervention should be made within 3–5 minutes because a severe hypoxia or severe circulatory failure may have induced the cyanosis. The name cyanosis, literally means "the blue disease" or "the blue condition". It is derived from the color cyan, which comes from kyanos, the Greek word for blue.
U.S. National Library of Medicine
