The minimal amount of resulting methemalbumin required to produce cyanosis is not stated in the literature. Anyone who has observed a specimen of venous blood in a tube can confirm that it is not blue. When hypoxemia is severe and cerebral oxygenation is impaired, confusion or coma can occur.

Hemoglobins that have an abnormally low affinity for oxygen high P 50 have decreased amounts of hemoglobin bound with oxygen at usual levels of Pa o 2. Hiremath G, Kamat D.

Diagnosis and treatment of disseminated intravascular coagulation. One approach to assessing the etiology of cyanosis is to obtain a heparinized arterial blood specimen.


Deficiency of the NADH methemoglobin reductase system is inherited in an autosomal recessive pattern. If the perifefica obtained is brown and does not change color on shaking in air, the plasma should be allowed to separate. We also report the results of our literature review on the subject.

As a point of reference, the standard suggested for patient rooms in Veterans Administration hospitals is 30 footcandles, so the recommended level of light intensity to detect cyanosis is likely to be exceeded in at least some patient examination areas.
