Atelectasis

Atelectasis is when part or all of a lung collapses. This happens because tiny air sacs in the lung, called alveoli, lose air and deflate.

A collapsed lung, or atelectasis, is a common problem after surgery. It can also be caused by other lung problems like cystic fibrosis, tumors, injuries to the chest, fluid buildup in the lungs, or weak breathing muscles. Even breathing in something foreign can lead to atelectasis.

If you have atelectasis, breathing can become difficult, especially if you already have lung disease. The treatment will depend on what caused the collapse and how severe it is. Different things can cause a lung to collapse, and atelectasis is a broader term than pneumothorax.

Pneumothorax is when air gets trapped between the lung and the chest wall. This trapped air can push on the lung, causing it to collapse. Pneumothorax is one possible reason why a lung might collapse (and thus, one possible cause of atelectasis).

Atelectasis, a condition where part of the lung collapses, might not show any obvious symptoms. However, if there are signs, they could include:

• Trouble breathing: This could feel like shortness of breath or difficulty catching your breath. It might be a gradual feeling or come on suddenly.

• Fast, shallow breathing: Your breaths might be coming more quickly than usual, and they might feel weaker or less deep.

• Wheezing: A whistling sound when you breathe, often more noticeable when you breathe out.

• Coughing: A persistent cough could be a sign, sometimes with phlegm or mucus.

It's crucial to seek immediate medical attention if you experience any trouble breathing. Many other health issues can also cause breathing problems, so getting a proper diagnosis is vital. If your breathing suddenly becomes very difficult or labored, call emergency services immediately.

If you're having trouble breathing, seek immediate medical attention. Difficulty breathing can be a symptom of many different health problems, not just atelectasis. A doctor needs to figure out the exact cause to give you the right treatment. If your breathing suddenly becomes labored, call emergency services right away.

Atelectasis is a condition where part of your lung collapses. This happens when air gets trapped in the tiny air sacs (alveoli) in your lungs, preventing them from fully expanding. There are two main types:

Obstructive Atelectasis: This happens when something blocks your airway. A blockage can be caused by:

• Mucus plugs: This is a buildup of phlegm (mucus) in your airways. It's common after surgery because you might not be able to cough effectively. Medicines used during surgery can also make your breathing shallower, allowing mucus to collect. Suctioning the lungs during surgery helps remove the mucus, but sometimes it still builds up. Mucus plugs can also affect people with cystic fibrosis, children, or those experiencing severe asthma attacks.
• Foreign objects: Children who inhale small objects like peanuts or toy parts are at risk of this type of atelectasis.
• Tumors: A growth in the airway, cancerous or not, can narrow or block the passage.

Non-obstructive Atelectasis: This is when pressure from outside the lung causes the collapse. Possible causes include:

• Injury: A chest injury, like from a fall or car accident, can cause pain and make it hard to take deep breaths. This can squeeze the lung, leading to atelectasis.
• Fluid buildup (pleural effusion): Extra fluid can build up between the lining of your lungs and your chest wall, putting pressure on the lung and causing it to collapse.
• Lung infection (pneumonia): Various lung infections can lead to atelectasis.
• Air leak (pneumothorax): When air leaks into the space between your lungs and chest wall, a lung can partially or fully collapse.
• Scarring: Past injuries, lung diseases, or surgeries can leave scar tissue, which can restrict lung expansion.
• Tumors: A large tumor pressing on the outside of the lung can squeeze it and force air out.

General anesthesia: A common cause of atelectasis, especially after major surgery, is general anesthesia. It disrupts your normal breathing patterns and can affect how well your lungs exchange oxygen and carbon dioxide. This disruption can cause the air sacs in your lungs to lose air. Nearly everyone who undergoes major surgery experiences some degree of atelectasis. Heart bypass surgery is particularly prone to this complication.

It's important to note that these are just some of the possible causes. If you're concerned about atelectasis, it's essential to discuss your specific situation with a healthcare professional.

Things that can increase your risk of atelectasis (collapsed lung) include:

• Trouble swallowing: If you have a condition that makes it hard to swallow, food or liquids might go into your lungs instead of your stomach. This can lead to atelectasis. Examples include certain types of neurological conditions or illnesses that affect the throat or esophagus.

• Being bedridden for a long time: Staying in bed for extended periods without moving around much can lead to the air sacs in your lungs not fully expanding. This can make you more prone to atelectasis. Regular position changes are crucial, even if you can't get out of bed. Turning from side to side or sitting up periodically can help.

• Lung diseases: Conditions like asthma, bronchiectasis, and cystic fibrosis can weaken your lungs and make them more susceptible to atelectasis. These diseases affect the airways and air sacs in the lungs, making it harder for them to function properly.

• Recent surgery (especially in the chest or stomach area): Surgery, particularly around the chest or stomach, can disrupt the normal functioning of the lungs. This increased risk is often temporary.

• Recent general anesthesia: The effects of general anesthesia can temporarily weaken your breathing muscles and make you more prone to atelectasis.

• Weak breathing muscles: Conditions like muscular dystrophy, spinal cord injuries, or other neuromuscular disorders can weaken the muscles you use to breathe. This makes it harder for your lungs to expand and contract, increasing your risk.

• Certain medications: Some medicines can weaken your breathing muscles, making you more likely to develop atelectasis. If you're concerned, talk to your doctor.

• Pain or injury: Pain from a stomach ache, a broken rib, or other injuries can make it difficult to cough. Coughing helps clear mucus and keep your lungs healthy. If you're experiencing pain, let your doctor know so they can suggest ways to manage it and prevent atelectasis.

• Smoking: Smoking damages the air sacs in your lungs, making them more prone to collapsing and increasing your risk for atelectasis. Quitting smoking is a significant step towards improving lung health.

Collapsed lung areas, particularly in adults, are often treatable. However, when a part of the lung collapses (called atelectasis), it can lead to several problems:

• Low blood oxygen (hypoxemia): When parts of your lungs collapse, they can't fully do their job of bringing oxygen into your bloodstream. This can lead to lower-than-normal oxygen levels in your blood.

• Pneumonia: Collapsed lung tissue makes it easier for bacteria or other germs to cause an infection, which can lead to pneumonia. The buildup of mucus in the collapsed area is a breeding ground for these germs. The risk of pneumonia remains until the collapsed lung tissue recovers.

• Respiratory failure: If a significant portion of a lung, or even an entire lung, collapses, especially in a baby or someone with pre-existing lung conditions, it can be very serious and even life-threatening. The body might not be able to get enough oxygen, and breathing can become dangerously difficult.

Atelectasis is a lung condition where part of the lung collapses. It can happen in both children and adults, but the causes and prevention differ.

In young children, atelectasis is frequently caused by something blocking their airways, like a small toy or object. To help prevent this, make sure small items are kept out of reach of young children. This simple precaution can significantly reduce the chances of their lungs collapsing.

In adults, atelectasis is most often a side effect of major surgery. The pressure and position changes during surgery can sometimes lead to lung collapse. If you're scheduled for surgery, talk to your doctor. They can discuss ways to reduce your risk. Some studies suggest that specific breathing exercises and exercises to strengthen the muscles used for breathing can help prevent atelectasis after certain types of surgery. Your doctor can explain which exercises might be right for you and how to do them safely.

Diagnosing atelectasis, a condition where part of the lung collapses, often starts with a simple checkup by a doctor and a chest X-ray. However, other tests might be needed to pinpoint the reason for the collapse, its severity, and the best treatment approach.

Additional Tests:

• CT Scan: A CT scan, or computed tomography scan, provides more detailed images than an X-ray. This is helpful in determining the exact cause and type of lung collapse. Imagine it as a more detailed X-ray, revealing small things an X-ray might miss.

• Oximetry: A simple test using a small sensor placed on your finger measures the amount of oxygen in your blood. This helps doctors understand how severe the lung collapse is and if your body is getting enough oxygen. Low oxygen levels indicate a more serious situation.

• Chest Ultrasound: This test uses sound waves to create pictures of the structures inside your chest. A small, hand-held device is gently pressed against your chest and moved around. It helps find the reason for the lung collapse, such as:

  • Pneumothorax: This happens when air leaks into the space between your lungs and chest wall, potentially causing the lung to collapse.
  • Pleural Effusion: This occurs when fluid builds up around your lungs, which can also lead to lung collapse. The ultrasound can help pinpoint the presence and amount of fluid.

• Bronchoscopy: A bronchoscopy involves inserting a thin, flexible tube with a light down your throat. This allows the doctor to see inside your airways. This can reveal:

  • Blockages: A bronchoscopy can identify things like mucus plugs, tumors, or foreign objects that might be blocking the airways and causing the lung collapse.
  • Removing Blockages: In some cases, the bronchoscope can be used to remove these blockages.

These additional tests provide more information than a basic X-ray, helping doctors determine the best course of treatment for atelectasis.

Atelectasis treatment varies depending on the cause. Sometimes, mild atelectasis (a collapsed lung) gets better on its own. If there's a problem like mucus buildup, medicines to thin and loosen the mucus might be used. If a blockage is causing the atelectasis, surgery or other procedures might be necessary.

Helping Your Lungs Recover (Chest Physical Therapy):

A group of techniques called chest physical therapy (or physiotherapy) can help your lungs re-expand after surgery or other procedures. Learning these techniques before surgery is ideal. These methods include:

• Deep Breathing Exercises: Using a handheld device called an incentive spirometer helps you practice taking deep breaths. This is followed by a deep cough to clear out mucus and secretions from your lungs, helping them return to their full size.
• Body Positioning: Lying with your head lower than your chest helps mucus drain from the bottom of your lungs.
• Percussion: Gently tapping on your chest over the collapsed area can loosen mucus.
• Mechanical Devices: Specialized devices, like an air pulse vest or handheld instruments, can help clear mucus.

Addressing Blockages (Surgery and Other Procedures):

If a blockage is the problem, methods like suctioning mucus or a bronchoscopy can clear the airway. A bronchoscopy involves a doctor using a thin, flexible tube to gently clear your airways. If a tumor is causing the atelectasis, the bronchoscopy might involve removing or shrinking the tumor, potentially needing surgery. Other cancer treatments like chemotherapy or radiation might also be part of the plan.

Breathing Support:

Sometimes, a breathing tube is needed. Continuous positive airway pressure (CPAP) can help people who are too weak to cough effectively and have low blood oxygen levels (hypoxemia), especially after surgery.
