Circumoral cyanosis can present as a serious condition requiring medical attention, or it may be a normal reaction for some. To distinguish when we should take action, let’s learn what signs to watch for and what to do in this situation. What Is Circumoral Cyanosis? To fully understand this condition, it is best to break down the meaning of its definition. Circumoral refers to the area surrounding or circling the mouth. Cyanosis refers to the bluish color of the skin resulting from low oxygen supply or blood circulation. We can expect to see circumoral cyanosis frequently in newborns since they have very fine skin surfaces. The bluish hue of their skin is actually from the blood vessels contained near the surface. Many also have a pinkish color to their skin due to strong blood circulation. However, this is decreased around the mouth region, intensifying the blue color of the veins. Circumoral cyanosis is the result of two cyanosis conditions called central cyanosis and peripheral cyanosis. Cyanosis conditions associated with central cyanosis are linked to serious cardiovascular diseases, whereas peripheral cyanosis relates to lung conditions. What Are the Sympt...

The term is derived from the Greek word kuaneos meaning dark blue. Hemoglobin In normal humans blood protein called hemoglobin serves to carry oxygen in the arteries to the different organs. Nearly all of the oxygen in the blood is carried by hemoglobin. A small portion is carried dissolved in blood in free form. Each gram of hemoglobin can combine with 1.34 mL of oxygen. While oxygenated hemoglobin is bright red, reduced hemoglobin is dark blue or purple in color. Venous blood is deoxygenated and is thus darker in color. This leads to the dusky or blue color of the skin and mucous membranes. (1-5) Cause of cyanosis Cyanosis is caused by an increase in the deoxygenated haemoglobin level to above 5 g/dL. In fact patients who have anemia do not develop cyanosis until the 2) falls below normal haemoglobin levels. In adults with normal hemoglobin (13.5-18 g/dL in men, 11.5-16 g/dL in women) central cyanosis is seen if oxygen saturation drops between 80 to 87%. Pa...
