Overview
Cyanosis is the condition that there is inadequate oxygen delivery to peripheral tissue. Oxygen in the blood is carried in two physiologic states. Approximately 2% is dissolved in plasma and the other 98% bound to hemoglobin. In central cyanosis there is increased level of deoxyhemoglobin around 3-5 g/dl.[1] In peripheral cyanosis there is increased oxygen extraction by the peripheral tissues.[2] .Several factors can affect the appearance of cyanosis includes skin pigmentation,Hemoglobin (Hb) levels, oxygen affinity to the hemoglobin (Hb).
