Understanding Collapsed Lung: What Happens and Why It Occurs

A collapsed lung, also called pneumothorax, happens when air leaks into the space between your lung and chest wall. This air pushes on the lung and causes it to shrink. Think of it like letting air out of a balloon—the balloon gets smaller as the air escapes. In a collapsed lung, the air doesn't escape from your body; instead, it collects in the wrong place and squeezes your lung.

There are two main types of collapsed lung. A spontaneous pneumothorax occurs without an obvious injury or trauma. This type often happens in tall, thin people, particularly men in their 20s and 30s. Smoking increases the risk of spontaneous collapse. A traumatic pneumothorax happens after an injury, such as a car accident, fall, or stab wound. The injury can damage the lung tissue or the chest wall, allowing air to enter the space around the lung.

Symptoms of a collapsed lung vary depending on how much of the lung has collapsed. Some people experience sudden sharp chest pain on one side. Shortness of breath is common, ranging from mild to severe. You might feel a tight sensation in your chest. In cases where only a small portion of the lung collapses, you may have few symptoms or notice them gradually. Large collapses cause more dramatic symptoms and require urgent attention.

According to research published in medical journals, spontaneous pneumothorax occurs in approximately 18 to 28 out of every 100,000 people annually in developed countries. Men are affected more often than women, with a ratio of roughly 6 to 1. Recurrence rates vary—if you've had one spontaneous collapse, there's about a 16 to 50 percent chance it could happen again, depending on whether treatment was surgical or non-surgical.

Practical Takeaway: If you experience sudden chest pain, shortness of breath, or a tight feeling in your chest, seek medical attention. A healthcare provider can use imaging tests to determine whether a collapsed lung is the cause and what treatment approach may be appropriate for your specific situation.

Initial Medical Evaluation and Diagnostic Testing

When you see a healthcare provider with symptoms of a collapsed lung, they will start with questions about when your symptoms began, whether you experienced any trauma or injury, and your medical history. The provider will listen to your lungs with a stethoscope to check for normal breathing sounds. They may also perform a physical exam and ask you to describe your symptoms in detail.

Chest X-rays are the standard first step for diagnosis. This imaging test shows whether air has entered the space around your lung and how much of the lung has collapsed. In a typical X-ray image, a collapsed lung appears as a dark area without the normal branching pattern of healthy lung tissue. Some healthcare facilities use CT scans for more detailed images, particularly if the collapse is small or if there's uncertainty about the diagnosis. CT scans provide clearer pictures of the lung and surrounding structures.

Blood tests may be ordered to check your overall health and oxygen levels. An arterial blood gas test measures oxygen and carbon dioxide levels in your blood. This information helps your healthcare provider understand how well your lungs are working and whether you need oxygen therapy. Pulse oximetry, a simple device that clips onto your finger, continuously measures oxygen levels in your blood during your hospital stay or evaluation.

In some cases, ultrasound may be used, particularly in emergency settings or for patients who cannot receive radiation from X-rays. Ultrasound uses sound waves to create images and can detect the presence of air in the pleural space (the area between the lung and chest wall). This method is becoming more common in emergency departments because it provides real-time information without radiation exposure.

Practical Takeaway: Keep records of any imaging tests you receive, including the dates and results. These records help you and your healthcare provider track the progress of treatment and make informed decisions about next steps. Ask your provider to explain what the images show and what it means for your treatment.

Conservative Treatment: Observation and Monitoring

For small collapsed lungs where the person is otherwise stable, observation may be the first approach. This means your healthcare provider watches the collapsed lung over time to see if it heals on its own. The body has a natural ability to reabsorb the air that has leaked into the pleural space. In many cases of small pneumothorax, the leak closes and the lung re-expands without additional intervention.

During observation, you'll need regular follow-up appointments and imaging tests to monitor progress. Most providers recommend X-rays every few days during the first week or two. You may have symptoms managed with rest and pain medication. While observing your collapsed lung, you should avoid strenuous activity, heavy lifting, and exercise. Air travel and diving should be avoided because pressure changes in these environments can worsen a collapsed lung or prevent healing.

Observation typically takes one to three weeks for the air to be reabsorbed. The timeline depends on the size of the collapse, how quickly your body reabsorbs the air, and your overall health. Younger, healthier individuals often heal faster than older adults or those with other lung conditions. Smoking slows the healing process, so quitting smoking during treatment improves outcomes.

This approach works well for about 30 to 50 percent of first-time spontaneous pneumothorax cases, according to medical literature. However, if the collapsed lung is larger (taking up more than 20 percent of the chest cavity), if you have severe symptoms, or if observation doesn't show improvement after a week or two, your healthcare provider will recommend a more active treatment.

Practical Takeaway: If your healthcare provider recommends observation, ask for clear instructions about what activities are safe and which ones to avoid. Understand the schedule for follow-up appointments and imaging. Know what symptoms would require you to seek immediate medical attention, such as worsening shortness of breath or chest pain.

Active Treatment Options: Aspiration and Chest Tubes

When observation isn't working or the collapsed lung is too large, healthcare providers use methods to remove the air that has accumulated around the lung. Aspiration is a procedure where a needle and small catheter (tube) are inserted into the pleural space to withdraw the air. This is less invasive than inserting a chest tube and can often be done in an outpatient setting or emergency department without admission to the hospital.

During aspiration, a provider uses ultrasound or X-ray guidance to position the needle precisely. The procedure typically takes 15 to 30 minutes. Local anesthesia numbs the skin and area around the insertion site. Many people describe this procedure as uncomfortable but not intensely painful. Success rates for aspiration range from 60 to 85 percent for first-time pneumothorax, meaning the lung re-expands and stays expanded.

A chest tube (also called a chest drain or thoracostomy tube) is used when a larger amount of air needs to be removed or when aspiration doesn't work. A healthcare provider inserts a flexible plastic tube through the chest wall into the pleural space. This tube allows air and fluid to drain out continuously. The tube is connected to a collection container and may be connected to suction, which helps draw air out faster. Chest tubes remain in place until the lung has re-expanded, which usually takes three to seven days.

While a chest tube is in place, you'll stay in the hospital and have regular monitoring. The tube site requires daily cleaning and dressing changes to prevent infection. Pain management is important—providers offer pain medication to keep you comfortable. You can usually move around and perform light activities with a chest tube. Most people describe the biggest inconvenience as being tethered to the drainage system and having movement limitations.

Practical Takeaway: Ask your healthcare provider which procedure they recommend for your situation and why. Understand what to expect during and after the procedure, including recovery time and any restrictions on activity. Know the signs of infection or complications, such as increased pain, fever, or drainage that looks abnormal.

Surgical Treatment and Long-Term Prevention

Surgical intervention becomes necessary when a collapsed lung doesn't respond to less invasive treatments, when there are repeated collapses, or when there are complications. The most common surgical procedure is called pleurodesis or pleurectomy. Pleurodesis involves coating the pleura (the membrane lining the lung) with a substance that causes the two layers to stick together, preventing air from accum
