Cyanosis
Cyanosis refers to the bluish coloration of the skin due to the presence of deoxygenated hemoglobin in blood vessels near the skin surface.
Types
It can occur in the fingers, including underneath the fingernails, as well as other extremities (called peripheral cyanosis), or in the lips and face (central cyanosis).
Central cyanosis
Central cyanosis suggests a circulatory or ventilatory problem that leads to poorer blood oxygenation in the lungs or greater oxygen extraction due to slowing down of blood circulation in the skin's blood vessels.
Acute cyanosis can be a result of asphyxiation or choking, and is one of the surest signs that respiration is being blocked.
The elementary principle behind cyanosis is that oxygenated hemoglobin is red, while deoxygenated hemoglobin is blue. Thus oxygen deficiency - hypoxia - leads to blue discoloration of the lips and other mucus membranes.
Peripheral cyanosis
Peripheral cyanosis suggests that there is poor circulation in the small vessels involved, such as when a person's hands are very cold. However, this condition can also be permanent even in normal temperatures; see acrocyanosis.

Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from inadequate oxygenation of the blood.........

Cyanosis is defined as at LEAST 5g/dL of de-oxygenated haemoglobin. At least 5g of de-oxygenated haemoglobin per 1 deci-litre of your blood.
De-oxygenated haemoglobin is haemoglobin that is not carrying oxygen (but usually carbon dioxide instead).
Cyanosis results in a bluish discoloration of your peripheries (hands and feet) if it is PERIPHERAL cyanosis. This is usually due to cold or hypovolaemic shock.
CENTRAL cyanosis due to heart or lung disease results in bluish discoloration of your tongue.

cyanosis means blue discoloration of the skin n mucous membranes ... this is due to the deoxygenated hemoglobin ... this means that there is some circulatory or ventilatory problem...so that the blood is not bein totally oxygenated.....

When a person becomes cyanotic, it is due to the absence of blood in the dermis. For example, when a person goes into shock, his/her blood rushes from the extremeties to the vital organs in the thoracic cavity. This leaves the person to look ashen.
