Is your skin turning blue? Let's talk about cyanosis!

Have you ever seen some people's skin, lips, or nails turn blue? Or maybe you have too. This is what is called cyanosis in medicine. What exactly is cyanosis? Why does this happen? Let's talk about it in detail today, just like talking to a friend.

What is cyanosis? Simply put...

Simply put, cyanosis is when your skin, lips, or fingernails take on a bluish appearance when there is a low amount of oxygen in your blood. If you have a darker skin tone, this bluish tinge may be more noticeable in your lips, gums, fingernails, and around your eyes. The word 'cyanosis' comes from the word 'cyan'. Cyan is a blue-green color.

Think about it this way. Normally, our red blood cells carry oxygen to every part of our body, to every tissue. When these red blood cells are well-oxygenated, they are bright red . Like a beautifully ripe cherry. So, when this oxygenated blood travels throughout our body, our skin takes on a pink or light red color. That's what a healthy look looks like.

However, if for some reason the blood does not receive enough oxygen , that is, if the oxygen level is low, that bright red blood turns a little darker, like a bluish purple . So, when this dark blood with less oxygen circulates in the body, the skin, lips, and nails start to look blue. Knowing where this blue color is most abundant in the body can help us find out what is causing it.

What does cyanosis mean? Is it serious?

Cyanosis is a sign that your organs, muscles, and other tissues are not getting enough oxygen to function properly . It's like a tree withering away without water. Our bodies can't do without oxygen either.

There are many different conditions and causes that can cause this condition of cyanosis. Sometimes, blue skin and blue lips can be a normal, harmless thing. For example, it can happen when you are exposed to extreme cold. However, there are some conditions that can be serious enough to require emergency medical treatment . Therefore, if you see the sign of cyanosis, it is not good to take it lightly.

The causes of cyanosis can mainly be related to our lungs, heart, or central nervous system (that is, the brain and spinal cord).

What are the types of cyanosis?

There are three main types of cyanosis. Let's take a look at what they are:

1. Blueness only around the mouth - Circumoral Cyanosis

This is when only your lips or around your mouth turn blue.This is sometimes called perioral cyanosis.

Imagine a baby, if he gets a little cold, his lips may turn blue. This is normal for newborn babies , so it's not something to worry about. Do you know what? When we are exposed to cold, the small blood vessels in our bodies, which we call blood vessels, constrict a little. Then the blood flow decreases a little, and therefore the oxygen supply decreases. That's why the lips turn blue.

Even older children, for example, when playing outside on a very cold day, or when they are in the cold early in the morning in an area like Nuwara Eliya, can have their lips turn blue. This usually goes away after a while when the body warms up.

2. Blue color of the limbs - Peripheral Cyanosis

In this type , only the hands, fingers, toes, and/or toes turn blue. Have you ever been in a very cold place and not worn socks or stockings? Your hands and feet can turn blue and feel numb. This is the same thing.

This is usually not life-threatening . However, it is important to find out what is causing it, as sometimes an underlying cause may require immediate treatment. Otherwise, permanent damage may occur.

3. Turning blue all over the body - Central Cyanosis

This is a condition that can be a little more serious than the other two types . In central cyanosis, in addition to the limbs, other parts of the body also turn blue . For example, areas like the chest, cheeks, tongue, gums, and lips.

This is often caused by serious conditions of the heart, lungs, or blood . Therefore, if you have these symptoms, it is extremely important to seek medical attention immediately .

What are the symptoms of cyanosis?

The main symptom is a bluish tinge to the skin . This bluish tinge can also be seen in your lips, tongue, gums, earlobes, and fingernails.

If you have dark skin, cyanosis may appear gray or pale. It is most noticeable on the lips, tongue, gums, fingernails, and around the eyes.

Because cyanosis is usually a symptom of another underlying medical condition, you may also experience other symptoms depending on the underlying cause. Some of them include:

• Low body temperature (Hypothermia)
• Numbness or tingling sensation in the hands and feet
• Cough
• Wheezing ( a sound coming from the chest cavity when breathing)
• Difficulty breathing
• Dizziness
• Feeling very tired (Fatigue)
• Weakness

What does cyanosis look like?

Depending on the type of cyanosis you have, your skin, lips, tongue, gums, eyes, or nails may appear various shades of blue or purple . As mentioned earlier, if you have dark skin, this may appear pale or gray .

What are the causes of cyanosis?

The main cause of cyanosis is not enough oxygen in your blood . This can be caused by two things: either your blood is actually low in oxygen, or your blood vessels are exposed to extreme cold.

Think about it, our organs and body parts are kept warm by the circulation of blood in our bodies. However, if the environment is very cold, in order to maintain our body temperature at a normal level, the blood vessels in our hands, feet, and ears constrict. This reduces the flow of blood, which can lead to a bluish color.

There are many other conditions and causes that can cause low levels of oxygen in the blood:

Airway problems

• Suffocation . For example, choking on food.
• Swelling around the vocal cords (e.g., croup)
• Infection and swelling of the epiglottis, the flap-like part of the throat that covers the windpipe.

Lung problems

• Going to high altitudes (far above sea level) where there is less oxygen in the air.
• Asthma disease.
• Respiratory tract infections .
• A blood clot in an artery in the lungs (pulmonary embolism).
• Chronic Obstructive Pulmonary Disease (COPD) (a long-term lung disease).
• Pulmonary hypertension (high blood pressure in the lungs).
• Pneumonia `(Pneumonia)` .

Heart problems

• Congenital heart defects , such as double outlet right ventricle and tetralogy of Fallot.
• Heart conditions (congestive heart failure).
• Sudden cessation of heart function (cardiac arrest ).

Other causes of cyanosis

• Restriction of blood circulation due to wearing tight clothing .
• Exposure to extreme cold .
• Raynaud's phenomenon , in which blood vessels suddenly narrow.
• Some medications used to treat high blood pressure.
• Seizures .
• Drug overdose.
• Exposure to toxic substances .

How to recognize cyanosis?

Because cyanosis is a symptom, your doctor will want to find out exactly what the underlying cause is .

First, the doctor will do a physical examination . Then they will ask you about your symptoms. They may ask questions like:

• When did you first notice this blue color?
• Did this come on suddenly, or did it increase gradually?
• Where on your body is blue?
• Have you traveled anywhere recently? (especially to high altitudes)
• Are you having trouble breathing?
• Are your hands or feet swollen?
• What other symptoms do you have?

What tests are used to diagnose cyanosis?

The doctor may order various tests to find the cause of cyanosis. These may include blood, lung, and heart tests:

• Pulse oximetry: This involves attaching a small device (like a clip) to your finger and measuring the amount of oxygen in your blood. It doesn't hurt.
• Arterial blood gas analysis (ABG): This involves taking a small sample of blood from your arteries (the blood that contains the most oxygen) and measuring the amount of oxygen and other substances in it.
• Chest X-ray .
• A chest computed tomography (CT) scan .
• Complete blood count (CBC) test .
• Electrocardiogram (EKG/ECG): This measures the electrical activity of the heart.
• Echocardiogram: This is an ultrasound test of the heart. It can look at the structure and function of the heart.
• Pulmonary function tests (PFTs): These help diagnose lung diseases.
• Cardiac catheterization: This test helps to diagnose heart disease in depth.

How is cyanosis treated?

Because cyanosis is a symptom caused by a variety of medical conditions, the treatment you receive will depend on the cause of your cyanosis .

One of the first treatments your doctor may give you is oxygen therapy . This is done by giving you extra oxygen, quickly increasing the oxygen level in your blood. Depending on the severity of your condition, you may need a breathing machine (ventilator).It may be necessary though.

Other treatment options are:

• Heat and massage: Cyanosis caused by exposure to cold or conditions such as Raynaud's phenomenon can be relieved by warming the affected areas and gently massaging them.
• Antibiotics: Antibiotics may be given for infections such as pneumonia.
• Other medications: Your doctor may prescribe other medications to treat heart and lung diseases.
• Stopping medication: Sometimes, if this condition is caused by certain medications you are currently taking, your doctor may advise you to stop taking those medications.
• Inhalers: If cyanosis is caused by a lung disease such as asthma or COPD, inhalers may be prescribed to help the lungs function better.
• Surgery: Congenital heart conditions, such as Tetralogy of Fallot, may require surgery shortly after birth.

How do I take care of myself?

If you have cyanosis due to a cold or a condition like Raynaud's phenomenon, you may need to make some changes to your lifestyle .

When you go out, especially on cold days, you should dress warmly . Even when you are at home, keep the room warm. The most important thing is to keep your body warm .

Also, if you are a smoker, you should stop it completely . Reduce your intake of caffeine-containing beverages (like tea and coffee) . Because both caffeine and nicotine cause your blood vessels to narrow. This increases the risk of cyanosis.

Can Cyanosis be prevented?

Because there are many causes of cyanosis, it is not possible to prevent all of them. However, there are some things you can do to reduce your risk of developing this condition:

• If you are taking any medications that restrict your blood flow, talk to your doctor about it and get advice on stopping them if necessary.
• Avoid smoking.
• Limit your caffeine intake.
• When going to a cold environment, dress warmly , especially covering parts like your ears, fingers, and nose.

What happens if I have cyanosis?

The outcome of your cyanosis depends on the cause and how quickly you seek treatment .

This is usually not life-threatening, but if you have other symptoms along with this bluish color, or if you develop cyanosis even when you are warm and at rest,Definitely see a doctor .

When should I seek medical advice? Is it an emergency?

Cyanosis can be caused by a variety of conditions and disorders. Some are more serious than others. If you have any of the following symptoms along with your skin turning blue, go to the emergency department of your nearest hospital immediately, or call 1990 :

• Difficulty breathing
• Chest pain
• Frequent headaches
• Fatigue
• Confusion (mood swings)
