Cyanosis
How is the condition diagnosed?
The healthcare provider can identify cyanosis by examining the person. The cause must then be found. A history and full exam will be needed first.
To help figure out the cause, other tests are often ordered. A blood test called a complete blood count, or CBC, can make sure there are a normal number of blood cells. A blood test called an arterial blood gas can measure the level of oxygen in the blood. A chest x-ray can show many heart and lung disorders. A test that uses sound waves to look at the heart, called an echocardiogram, may be used. This test can show many of the congenital heart defects that may cause cyanosis and measure how well the heart is pumping blood. Other tests may be needed in some cases.
