==Overview==
==Overview==
In [[central cyanosis]] saturation of [[oxygen]] is less than 85% when there is reduced hemoglobin more than 5g/dl following a [[intrapulmonary shunt]] or [[intracardiac shunt]] leading to mixing of arterial and venous [[ oxygen]] content. In [[peripheral cyanosis]], the saturation of [[oxygen]] is normal and there is [[peripheral capillary bed]] [[vasoconstriction]] due to low [[cardiac output]] state or [[sepsis]].

Overview

In central cyanosis saturation of oxygen is less than 85% when there is reduced hemoglobin more than 5g/dl following a intrapulmonary shunt or intracardiac shunt leading to mixing of arterial and venous oxygen content. In peripheral cyanosis, the saturation of oxygen is normal and there is peripheral capillary bed vasoconstriction due to low cardiac output state or sepsis.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Common Causes

Central Cyanosis

There following are some of the common causes of central cyanosis:

Peripheral Cyanosis:

There following are some of the common causes of peripheral cyanosis: [34][35]

Pseudocyanosis:
