Peripheral cyanosis affects the fingers and toes. It happens when the body is not able to pump oxygen-rich blood to those areas, whether due to the cold or a health condition.
Cyanosis refers to a bluish, purplish, or grayish cast to the skin and mucous membranes. A type known as peripheral cyanosis, or acrocyanosis, primarily affects the hands and feet.
Sometimes cold temperatures can cause the narrowing of blood vessels and lead to blue-tinged skin. Warming or massaging the blue areas should return the necessary blood flow and color to the skin.
If warming up your hands and feet doesn’t restore blood flow and color, you may have an underlying condition.
Whatever the cause, the discoloration means that something’s interfering with your body’s ability to deliver oxygen-rich blood to the tissues that need them. It’s important to restore oxygen to body tissues as soon as possible to prevent complications.
Blood that’s rich in oxygen is the bright red color typically associated with blood. When blood has a lower level of oxygen and becomes a darker red, more blue light is reflected, making the skin appear to have a blue or gray tint.
Being cold is the most common cause of blue hands or feet. It’s also possible to have blue hands or feet even though your extremities are warm.
Peripheral cyanosis can signal an issue with your body’s system of delivering oxygen-rich blood to the tissues of your hands and feet. It may also be the result of low oxygen levels in the red blood cells.
Your blood is responsible for carrying oxygen through your body, traveling from your lungs to your heart. There, it is pumped through your arteries to the rest of your body.
After blood is delivered to your body’s tissues, the oxygen-depleted blood returns to your heart and lungs through your veins.
If anything prevents blood from returning to your heart through your veins or stops blood from reaching your tissues in the first place, your tissues won’t get the oxygen-rich blood they need.
Hemoglobin levels typically range from 12.0 to 15.5 grams per deciliter (g/dL) for females and 13.5 to 17.5 g/dL for males, according to the American Red Cross.
Cyanosis is typically noticeable when the concentration of deoxygenated hemoglobin is at least 3 to 5 g/dL.
Peripheral cyanosis typically affects the hands, fingertips, and toes. It is rarely life threatening. Unlike some other types of cyanosis, it doesn’t typically affect the mucous membranes. In some cases, cyanosis can affect the skin around the mouth.
In some people, the affected areas may appear purplish instead of bluish.
Bluish skin can be a sign of something serious. If your natural color doesn’t return when your skin is warmed, seek medical attention right away.
To determine a cause, a doctor will need to perform a physical examination. They may listen to your heart and lungs. You may have to provide a blood sample and undergo other tests.
A doctor may use or order:
•a noninvasive pulse oximeter to measure the oxygenation of your blood
•an arterial blood gas test to measure the acidity and the levels of oxygen and carbon dioxide in your blood
•a chest X-ray or CT scan to evaluate your heart and lungs
Treatment involves identifying and correcting the underlying cause to restore the oxygenated blood flow to the affected parts of the body.
Some medications can help relax the blood vessels. They may include:
•antidepressants
•antihypertension drugs
•erectile dysfunction drugs
Using these medications to treat peripheral cyanosis is considered off-label drug use.
Peripheral cyanosis is most often caused by cold weather. Once your body warms up, your discolored hands or feet should return to their natural color.
However, it’s also possible that an underlying condition is causing the discoloration. Seek immediate medical attention if that seems to be the case, or if you have other notable symptoms, such as trouble breathing.
