---

central cyanosis  that due to arterial unsaturation, the aortic blood carrying reduced hemoglobin.

enterogenous cyanosis  a syndrome due to absorption of nitrites and sulfides from the intestine, marked primarily by methemoglobinemia and/or sulfhemoglobinemia with cyanosis, as well as severe enteritis, constipation or diarrhea, headache, dyspnea, dizziness, syncope, and anemia.

peripheral cyanosis  that due to an excessive amount of reduced hemoglobin in the venous blood as a result of extensive oxygen extraction at the capillary level.

pulmonary cyanosis  central cyanosis due to poor oxygenation of the blood in the lungs.

cyanosis re´tinae  cyanosis of the retina, observable in certain congenital cardiac defects.

shunt cyanosis  central cyanosis due to the mixing of unoxygenated blood with arterial blood in the heart or great vessels.

A condition resembling cyanosis, caused by the absorption of nitrites or other toxics from the intestine and by the formation of methemoglobin or sulfhemoglobin in the blood.

a bluish discoloration of the skin and mucous membranes due to excessive concentration of reduced hemoglobin in the blood. Used wrongly by clinicians describing skin lesions in pigs where there is severe congestion of cutaneous vessels and some leakage of blood into perivascular tissues.

enterogenous cyanosis

a syndrome due to absorption of nitrites and sulfides from the intestine, principally marked by methemoglobinemia and/or sulfhemoglobinemia associated with cyanosis.

peripheral cyanosis

that due to an excessive amount of reduced hemoglobin in the venous blood as a result of extensive oxygen extraction at the capillary level.
