tsüanoosi

Tsüanoosi is a medical condition characterized by a bluish or purplish discoloration of the skin and mucous membranes. This coloration is caused by an increased concentration of deoxygenated hemoglobin in the blood. Hemoglobin is the protein in red blood cells responsible for carrying oxygen. When hemoglobin is not carrying oxygen, it appears darker and can give the skin a blue hue.

Tsüanoosi can be either central or peripheral. Central tsüanoosi affects the entire body, including the lips, tongue, and trunk, and is typically caused by a problem with the lungs or heart that impairs oxygenation of the blood. Conditions like pneumonia, chronic obstructive pulmonary disease (COPD), or congenital heart defects can lead to central tsüanoosi. Peripheral tsüanoosi, on the other hand, affects the extremities, such as the fingers and toes, and is usually due to poor circulation or exposure to cold. This can occur when blood flow is reduced to these areas, leading to more deoxygenated blood being present.

The severity of tsüanoosi can vary. Mild cases may be barely noticeable, while severe cases can be a sign of a life-threatening condition. Diagnosis involves a physical examination and may include blood tests to measure oxygen levels, as well as imaging studies to assess the heart and lungs. Treatment focuses on addressing the underlying cause of the reduced oxygenation or poor circulation.
