Pneumothorax (Collapsed Lung): A Comprehensive Guide — Symptoms, Causes & Treatment

Pneumothorax, or a collapsed lung, occurs when air leaks into the space between your lung and chest wall, causing the lung to collapse. This can cause sudden chest pain and shortness of breath. While some cases are minor, a large pneumothorax or a tension pneumothorax is a medical emergency requiring immediate treatment to prevent life-threatening complications.

Early symptoms

• Sudden, sharp chest pain on one side
• Shortness of breath (dyspnea)
• A feeling of tightness in the chest
• Dry, hacking cough
• Pain that worsens with a deep breath or cough

Severe symptoms — seek medical care

• Severe shortness of breath
• Rapid heart rate (tachycardia)
• Rapid breathing (tachypnea)
• Bluish discoloration of the skin or lips (cyanosis)
• Profound fatigue or weakness
• Low blood pressure (hypotension)

Common causes

• Rupture of subpleural blebs or bullae
• No identifiable underlying lung disease
• Chronic Obstructive Pulmonary Disease (COPD)
• Asthma
• Cystic Fibrosis
• Lung cancer
• Interstitial lung disease
• Infections like pneumonia or tuberculosis

Frequently Asked Questions

What does a collapsed lung feel like?

A collapsed lung typically feels like a sudden, sharp, stabbing pain on one side of your chest. This pain often worsens when you take a deep breath or cough, a characteristic known as pleuritic chest pain. Alongside the pain, the most common sensation is shortness of breath, which can range from mild to severe depending on the size of the pneumothorax and your underlying lung health. Some people also describe a feeling of tightness or pressure in their chest. The onset is usually abrupt and can happen even at rest.

Is a pneumothorax serious or dangerous?

Yes, a pneumothorax can be very serious and potentially life-threatening. The level of danger depends on the type and size. A small primary spontaneous pneumothorax in a healthy individual might resolve on its own with monitoring. However, a large pneumothorax can significantly impair breathing and oxygen levels. The most dangerous form is a tension pneumothorax, which is a medical emergency. In this condition, air continuously builds up in the chest cavity, compressing the lung, heart, and major blood vessels, which can lead to cardiovascular collapse and death if not treated immediately [4].

Can a collapsed lung be cured?

Yes, a collapsed lung can be fully treated, and the lung can be re-expanded. The term 'cure' can be complex because the main issue is preventing it from happening again. The immediate treatment aims to remove the air from the pleural space, allowing the lung to function normally. Procedures like chemical or surgical pleurodesis are performed specifically to prevent recurrence. While these procedures significantly lower the chance of another pneumothorax, they don't offer a 100% guarantee. For many people, especially after a successful pleurodesis, they may never experience another episode [2].

How long does it take to recover from a pneumothorax?

Recovery time varies greatly depending on the severity and the treatment received. For a small pneumothorax treated with observation, it may take 1-2 weeks for the air to be fully reabsorbed. If a chest tube is required, you might be in the hospital for several days until the air leak seals. After surgery like VATS with pleurodesis, hospital stay is typically 3-7 days. Full recovery, including the resolution of pain and return to normal activities, can take anywhere from 4 to 8 weeks. Your doctor will provide specific guidance on resuming work, exercise, and other activities [5].

Can I exercise or work with a pneumothorax?

During the acute phase of a pneumothorax, you should not exercise and will likely be unable to work. Rest is crucial to allow the lung to heal. After treatment, you will have activity restrictions. Strenuous activities, heavy lifting, and contact sports are typically prohibited for several weeks to a month or more to prevent recurrence. Your return to work depends on the physical demands of your job. Desk jobs can be resumed sooner, while physically demanding jobs require a longer recovery period. Always follow your doctor's specific advice on activity levels after treatment.

Is a pneumothorax hereditary?

While most cases of spontaneous pneumothorax are not directly hereditary, there can be a genetic predisposition. Some rare genetic disorders are strongly associated with an increased risk of pneumothorax, such as Marfan syndrome, Birt-Hogg-Dubé (BHD) syndrome, and vascular Ehlers-Danlos syndrome. These conditions affect connective tissue, making the lung tissue more prone to developing blebs and rupturing. If there is a strong family history of collapsed lungs, especially at a young age, your doctor might consider investigating for an underlying genetic condition [1].

What should I avoid after having a pneumothorax?

After a pneumothorax, the most critical thing to avoid is smoking, as it dramatically increases the risk of recurrence. You should also avoid activities that involve significant pressure changes. This includes scuba diving, which is generally considered an absolute contraindication for life. Flying in commercial aircraft should be avoided for a period after treatment (often 1-2 weeks after the lung is confirmed to be fully re-expanded by X-ray). High altitudes, playing wind instruments, and activities involving straining (like heavy lifting) should also be avoided until your doctor gives you clearance [2].

How do I know if the treatment is working?

The primary signs that treatment is working are the improvement of your symptoms, specifically a reduction in chest pain and easier breathing. If you have a chest tube, your medical team will monitor it for an air leak (bubbling in the chamber), and the cessation of this bubbling is a key sign the lung has sealed. The definitive way to know if treatment is working is through follow-up imaging. A chest X-ray will be performed to visually confirm that the lung has re-expanded and is staying inflated against the chest wall [4].
