What is cyanosis? Know the disease and know its symptoms – Ser Saúde

THE cyanosis is a clinical manifestation of low oxygen saturation in arterial blood, defined as a blue leather and nails, according to information from the Brazilian Automobile Society (SBA).

The symptom is most easily seen on the mucous membranes and skin of the earlobes, lips and fingers. It occurs because of a lack of oxygen in the blood.

Diseases associated with cyanosis

Cyanosis can be due to several types of severe lung or heart disease which lowers the level of oxygen in the blood.

It may also be due to a congenital heart defect that allows blood to flow directly to the heart, without going through the alveoli of the lungs, where oxygen is released from the air, according to Rebecca Dezube of Johns Hopkins University. article published by MHS laboratory.

types of cyanosis

Cyanosis can be defined in terms of speed, blood circulation and oxygen content. See 3 types:

  • peripheral: when the speed of circulation decreases, there is not enough blood circulation of oxygen to the whole body;
  • Kati: when blood reaches the arteries without oxygen, the main causes are lung diseases;
  • mixed: when not only is the oxygen process in the lungs damaged, but also the heart cannot promote adequate oxygen-carrying blood.

The concentration of oxygen in the blood can be estimated by oximetry of pulseswhich the sensor is located on the finger or ear lobe, or can be measured directly by analyzing arterial blood gases.

Chest radiography, echocardiography, cardiac catheterization, lung function tests, and frequent, additional tests may be needed to determine the cause of a decrease in oxygen concentration in the blood, leading to cyanosis, according to Rebecca Dezube.

THE oxygen therapy it is usually a preliminary treatment, as in other cases where the level of oxygen in the blood is low. Many of the defects that lead to deviation can be treated with surgery or other procedures.
