There are two types of cyanosis, Moreno-Walton says. Peripheral cyanosis causes a blue tinge in the fingers, nail beds or even the limbs. Central cyanosis affects the tongue and mucous membranes. "All the things that cause central cyanosis will result in peripheral cyanosis, but all peripheral cyanosis is not the result of central cyanosis.

Cyanosis is the medical term for when your skin, lips or nails turn blue due to a lack of oxygen in your blood. If you have darker skin, cyanosis may be easier to see in your lips, gums, nails and around your eyes. The word cyanosis comes from the word cyan. Cyan is a blue-green color.

The most common symptom of TOF is cyanosis, which is when the skin, lips and nail beds are blueish in color. Cyanosis is the result of too much oxygen-poor blood being pumped through the body. Cyanosis may come in sudden spells, called tet spells, when a baby is crying or feeding. It happens when a baby's blood oxygen level drops quickly.

Cyanosis is a pathologic condition that is characterized by a bluish discoloration of the skin or mucous membrane1 [1]. The word cyanosis is a derivative of the word cyan, a blue-green color. The presence of cyanosis can pose a serious diagnostic challenge.

Cyanosis is a bluish discoloration of the skin, mucous membranes, tongue, lips, or nail beds and is due to an increased concentration of reduced hemoglobin (Hb) in the circulation.1 Clinically evident cyanosis typically occurs at an oxygen saturation of 85% or less. 2 Mild cyanosis may be difficult to detect.

In addition to a physical examination, diagnostic testing for cyanosis may include: Blood oxygen saturation by pulse oximetry. Arterial blood gas analysis (ABG) Complete blood count (CBC) Electrocardiogram or Echocardiogram. Chest X-ray. Chest computed tomography (CT) scan.
