Are your lungs collapsing? Let's talk about atelectasis!

Have you ever felt a strange, heavy feeling in your chest when you breathe? Or do you suddenly feel like you're having trouble breathing? Perhaps you've recently had major surgery or are suffering from another respiratory condition, this may be very important to you. Today we're going to talk about atelectasis, a condition in which part of a lung, or sometimes the entire lung, collapses . Don't worry, this is something that can be managed if you understand it properly.

Simply put, what is atelectasis?

Okay, let's first look at what atelectasis is. Simply put, it's when one or more of the tiny air sacs (alveoli) in our lungs fail to inflate properly and collapse.

You know what happens when we breathe. The air we inhale goes into the lungs and into these air sacs called alveoli. That's where the oxygen in the air gets mixed with our blood. Then that oxygen-filled blood goes throughout the body, supplying all of our organs and tissues with the oxygen they need to survive.

Now imagine, what happens if these air sacs (alveoli) don't get enough air to inflate properly, or if they get compressed by something outside? That's when they collapse. This is what we call atelectasis. This can happen in a small part of the lung, or it can affect the entire lung. The important thing is, if a significant amount of the lung collapses in this way, our blood may not get enough oxygen. Then various health problems may arise.

What is the difference between Atelectasis and Pneumothorax?

These two names may be confusing to you, so let's explain the difference between the two.

• Atelectasis , as I mentioned earlier, is the collapse of the air sacs (alveoli) in the lungs or a part of the lung itself. In this case, the problem lies within the lung itself.
• Pneumothorax is when air leaks into the space around the lung, pushing the lung in and causing it to collapse. In this case, the pressure comes from outside the lung.

Did you see the difference? One from the inside, the other from the outside.

What does atelectasis indicate?

If you have not recently had chest or abdominal surgery, if you are diagnosed with atelectasis, it may indicate that there is some kind of obstruction in your airway . This obstruction is what causes part or all of your lung to collapse.

Who is at higher risk of developing this?

There are a few people who are at higher risk of developing atelectasis. Let's take a look at who they are:

• People who have had chest or abdominal surgery: You may not be able to breathe deeply, especially due to the anesthesia used to keep you asleep during surgery. This means your lungs won't inflate properly.
• People with conditions that block the small airways (like the bronchi) in the lungs: This reduces the lungs' ability to expand normally.
• People with chest injuries or broken ribs: The intense pain at times like this makes it difficult to breathe deeply.
• People exposed to tobacco smoke.

What are the types of atelectasis?

There are three main types of atelectasis: Compressive, Resorptive/Obstructive, and Contraction. Sounds a bit complicated? Let's keep it simple.

1. Compressive atelectasis

This is when something around the lung – such as fluid, air, blood, or a tumor – puts pressure on the lung, causing it to collapse. It's like squeezing the outside of a balloon and causing it to collapse.

2. Resorptive/obstructive atelectasis

This is what happens: The air sacs in your lungs (alveoli) absorb oxygen and carbon dioxide into your blood, but there is no way for new air to get in. Then those air sacs empty and become stuffy. Surgeries that require anesthesia are a major cause of this.

Also, if something inside the lung (for example, a lump, a tumor, or a small object you accidentally swallowed) gets stuck and prevents air from getting in, this can cause ``Resorptive atelectasis``. This is also called ``Obstructive atelectasis`` .

3. Contraction atelectasis

This is caused by scarring (fibrosis) in the lungs. This scarring prevents the air sacs (alveoli) from opening properly.

Other types

Newborn babies, especially premature babies or those with acute respiratory distress syndrome (ARDS), can develop a rare form of patchy atelectasis. This occurs when there is not enough of a protein (called surfactant) that keeps the lungs from collapsing.

In addition, names such as bibasilar atelectasis, rounded atelectasis, gravity-dependent atelectasis, and subsegmental atelectasis refer to the location, appearance, or severity of the collapse.

What are the symptoms?

Most of the time, atelectasis does not cause any symptoms . However, if there is an underlying medical condition (such as COPD) that is causing the atelectasis, it may cause symptoms.

However, if atelectasis affects a large area of ​​your lungs, your blood oxygen levels may drop. This is called hypoxemia. Symptoms such as these may occur:

• Difficulty breathing / shortness of breath (dyspnea)
• Cough
• Chest pain
• Rapid breathing (tachypnea)
• Blue skin and lips

What is the most common reason?

The most common cause of atelectasis is surgery . When anesthesia is used to keep you asleep during surgery, you don't breathe deeply. You also don't cough properly to clear the mucus in your lungs. This can cause your airways to become blocked and prevent air from reaching the alveoli. This is when resorptive atelectasis occurs.

What are the other reasons?

There are several other reasons besides surgery.

• Mucus plug: This is common after surgery, in young children, people with cystic fibrosis, and during severe asthma attacks.
• Inhaled object: Small objects, especially small children, can be accidentally swallowed, such as small pieces of toys or food. These can become lodged in the airways and block the lungs.
• Fluid accumulation around the lungs (pleural effusion): This is usually caused by an underlying medical condition, such as heart disease.
• Air accumulation around the lungs (pneumothorax).
• Non-cancerous (benign) tumors.
• Cancerous tumors.
• Scarring of the lungs.
• Underlying diseases: Atelectasis can also be caused by conditions such as chronic obstructive pulmonary disease (COPD) or acute respiratory distress syndrome (ARDS), and respiratory infections such as COVID-19 or pneumonia.

How do you recognize this?

The first step in diagnosing atelectasis is to get a chest X-ray . This takes a picture of your lungs. If necessary, your doctor may also order a CT scan (Computed Tomography scan) to get more detailed images.

Sometimes, your doctor may need to look inside your lungs. This is done by passing a small camera-equipped tube down your throat. This is called a bronchoscopy . During this test, any blockages in your airways can be removed.

What are the treatments?

Most cases of atelectasis resolve without any specific treatment, under close medical supervision.

Other treatments depend on the cause of the swelling and its severity. They may include:

• Deep breathing exercises (`incentive spirometry`): This involves practicing deep breathing using a small device.
• Removing blockages in the lungs: This is usually done through a bronchoscopy test.
• Physical therapy: This involves exercises that help expand the lungs.
• Inhaled medicines that open the airways (bronchodilators).
• Treatment of tumors or chronic lung diseases.

Remember, your doctor will decide on your treatment plan, so it is very important to follow your doctor's instructions.

How to reduce the risk?

There are several things you can do to reduce your risk of atelectasis:

• After surgery: Get up and walk as soon as your doctor tells you to, do breathing exercises, and use an incentive spirometer.
• If you have any underlying medical conditions: Get the condition treated properly. Follow your doctor's instructions.
• If you smoke, stop it, or don't start. Smoking is very bad for your lungs.
• If you have small children: Do not leave small toys or food items where they can choke.

Is this a serious situation?

Atelectasis is usually not a serious condition . However, in some cases, serious complications can occur:

• Low blood oxygen levels (hypoxemia): When air cannot reach the alveoli due to lung congestion, the blood does not receive oxygen, and tissues and organs do not receive oxygen.
• Pneumonia: If mucus accumulates in the blocked airways, it can become infected.
• Respiratory failure: In severe cases (for example, if an entire lung is affected), respiratory failure can occur. This can be life-threatening.

How is the outlook?

The good news is that most of the time, atelectasis will reverse itself (recover) once the underlying cause is treated. Most people recover quickly and have no long-term serious effects. However, someone with a long-term (chronic) condition may need additional treatment to manage the underlying cause of atelectasis.

How do I take care of myself?

The best thing you can do is to follow your doctor's instructions carefully after surgery. Also, if you have any underlying conditions that increase your risk of atelectasis, manage them well.

When should you see a doctor?

If you have recently had surgery, have an underlying medical condition, develop any new symptoms, or are concerned about any symptoms, see your doctor immediately.

Our lungs are very complex and very important organs. They are responsible for keeping air in, oxygenating the blood, and keeping all the tissues and organs in the body functioning properly. Atelectasis is when one part of this system doesn't work as it should. Saying "a collapsed lung" - even a small part - can be a bit scary. But, fortunately, most of the time, atelectasis is not a serious enough condition to be life-threatening.

For your attention: some important points

Okay, so, from what we've talked about, these are the most important things you need to remember:

• Atelectasis is the collapse of the air sacs (alveoli) in the lungs.
• The most common cause is surgery, but there are other causes, such as mucus blockage, swallowing something, tumors, and lung disease.
• Most of the time, there are no symptoms, but things like difficulty breathing, coughing, and chest pain can occur.
• Practicing deep breathing exercises and avoiding smoking after surgery can help reduce the risk.
• This condition can often be cured.
• If you have any doubts or discomfort, seek medical advice immediately.

I hope you find this information useful. Stay healthy!
