Kerk N, Goerge T. Principios de Medicina Interna. Anyone who has observed a specimen of venous blood in a tube can confirm that it is not blue. One group has recommended using less than 20 footcandles of illumination.
Necrosis por droga vasoactiva. Some methemoglobin is normally formed in the body, but this is usually reduced to deoxyhemoglobin by the NADH methemoglobin reductase system. If the plasma is brown, methemalbumin is likely to be present.
Skin necrosis must be considered as a syndrome, because it is a clinical manifestation of different diseases. Deficiency of the NADH methemoglobin reductase system is inherited in an autosomal recessive pattern. Similar articles in PubMed.

While this is most frequently attributable to increased amounts of unoxygenated hemoglobin deoxyhemoglobin in the vasculature, there are other causes of bluish skin color.

The bluish skin color associated with hemosiderin deposition is more apparent in parts of the body with less melanotic pigment. J Perinatol ; Pigmentation of the skin. Comparison of colchicine, dapsone, triamcinolone, and diphenhydramine therapy for the treatment of brown recluse spider envenomation: Peripheral chemoreceptors may be stimulated by a low Pa cianoeis 2causing increased ventilation with dyspnea and tachypnea.
Since loading hemoglobin with oxygen is not affected, whereas unloading oxygen from hemoglobin is facilitated, tissue oxygen is high, and suppression of erythropoietin may produce a mild anemia. Daylight or artificial light sources simulating daylight’s spectral composition are not necessarily optimal for detecting cyanosis.

Meaning of “cianosis” in the Spanish dictionary
Finding characterized by slowing of blood flow to a peripheral body region in association with an increase in oxygen extraction from normally saturated arterial blood.
A bright red arterial specimen obtained in a patient with generalized blue skin color should lead one to suspect deposition of nonheme pigment in the periferrica.
Med Clin North Am. Br Med J ; Cyanosis can result on occasion. The importance of arterial blood gas analysis in detecting hypoxemia cannot be overemphasized.

Post-graduate Medicine On-line ; 3. Creager M, Dzau V. When cyanosis is due to arterial hypoxemia, other signs and symptoms are usually present. The pigment may be present in the blood when excessive breakdown of red cells results in saturation of haptoglobin with hemoglobin. Cyanosis, Peripheral Cyanosis, Central Cyanosis.
