A collapsed lung can heal naturally or with treatment, but recovery depends on severity and timely medical care.
Understanding What Happens When a Lung Collapses
A collapsed lung, medically known as pneumothorax, occurs when air leaks into the space between the lung and chest wall. This air buildup pushes on the lung, causing it to shrink or collapse partially or completely. The result is difficulty breathing, chest pain, and decreased oxygen levels in the blood.
The causes of a collapsed lung vary widely. It can happen spontaneously without any obvious reason, especially in tall, thin young adults. Injuries like broken ribs or penetrating chest wounds can also puncture the lung. Certain medical procedures and underlying lung diseases such as chronic obstructive pulmonary disease (COPD) increase the risk too.
The key question many people ask is: Do collapsed lungs heal? The answer depends on the type of pneumothorax and how quickly it’s treated. Some cases resolve on their own, while others require urgent intervention.
Types of Pneumothorax and Their Healing Potential
Spontaneous Pneumothorax
Spontaneous pneumothorax occurs without trauma or obvious cause. It’s divided into two types:
- Primary spontaneous pneumothorax: Happens in people without known lung disease.
- Secondary spontaneous pneumothorax: Occurs in people with underlying lung conditions like emphysema or cystic fibrosis.
Primary spontaneous pneumothorax often affects young adults who smoke or have certain genetic traits. In many cases, small collapses heal by themselves within days to weeks as the trapped air gets absorbed by the body.
Secondary spontaneous pneumothorax tends to be more severe because diseased lungs don’t function well. Healing is slower and often requires medical treatment to prevent complications.
Tension Pneumothorax
Tension pneumothorax is a life-threatening emergency where air enters the chest cavity but cannot escape. This causes pressure to build up rapidly, compressing the heart and other lung. Immediate intervention is required to release the trapped air.
Because of its severity, healing only begins after emergency treatment stabilizes the patient. Without prompt care, this condition can be fatal.
Traumatic Pneumothorax
Traumatic pneumothorax results from blunt or penetrating chest injuries such as car accidents or gunshot wounds. The extent of healing depends on injury severity and whether complications like infection occur.
In many cases, surgery or chest tube placement is needed to re-expand the lung and allow healing.
The Natural Healing Process of a Collapsed Lung
When a lung collapses partially due to trapped air outside it, the body works to absorb this air over time. The pleural space—the gap between the lung lining and chest wall—normally contains a small amount of lubricating fluid but no air.
Once air leaks into this space, it disrupts normal pressure balance needed for lung expansion during breathing. The body gradually absorbs this free air through blood vessels lining the pleura.
How long does this take? For small pneumothoraces (less than 20% of lung collapse), absorption can occur within 1-2 weeks without invasive treatment. During this time, patients may experience mild symptoms like shortness of breath but often recover fully if monitored closely.
However, larger collapses take longer to heal naturally—sometimes several weeks—and carry risks of complications like persistent air leaks or infections.
Treatment Options That Promote Lung Healing
For moderate to severe collapsed lungs or those causing significant symptoms, medical intervention speeds healing and prevents further damage.
Oxygen Therapy
Supplemental oxygen helps increase the rate at which trapped air is absorbed from the pleural space. Breathing high concentrations of oxygen reduces nitrogen levels in blood and tissues, creating a gradient that pulls nitrogen out from trapped air pockets faster.
This non-invasive approach works well for smaller pneumothoraces under close supervision by healthcare providers.
Needle Aspiration & Chest Tube Insertion
If a collapsed lung is larger or symptoms worsen, doctors may remove trapped air using:
- Needle aspiration: A needle inserted into the chest removes excess air.
- Chest tube drainage: A flexible tube placed through the chest wall continuously evacuates air until healing completes.
These procedures allow lungs to re-expand fully faster than natural absorption alone. Chest tubes are typically left in place for several days until no more air leaks out.
Surgery for Persistent or Recurrent Cases
Some patients develop persistent leaks that don’t heal with conservative measures. Surgery may be necessary to repair holes in the lung lining (pleura) or remove damaged tissue causing repeated collapse episodes.
Procedures include:
- Video-assisted thoracoscopic surgery (VATS): Minimally invasive surgery using small incisions.
- Pleurodesis: A technique that intentionally causes pleural layers to stick together permanently preventing future collapses.
Surgical intervention usually leads to complete recovery but requires longer hospital stays and follow-up care.
The Timeline: How Long Does It Take For a Collapsed Lung To Heal?
Healing time varies widely depending on factors such as size of collapse, patient health status, treatment method used, and presence of complications like infections or underlying diseases.
| Pneumothorax Type | Treatment Approach | Typical Healing Time |
|---|---|---|
| Small primary spontaneous pneumothorax | Observation + oxygen therapy | 1-2 weeks |
| Moderate pneumothorax (20-40%) | Needle aspiration/chest tube drainage | 2-4 weeks |
| Tension pneumothorax (emergency) | Immediate decompression + surgery if needed | Variable; days to weeks post-treatment recovery |
| Pneumothorax with underlying lung disease (secondary) | Aggressive treatment + possible surgery | Several weeks to months depending on condition severity |
| Persistent/recurrent pneumothorax after initial treatment | Surgical repair/pleurodesis | Weeks post-surgery for full recovery |
Even after apparent healing on imaging tests like X-rays or CT scans, patients may need follow-up visits for months to ensure full functional recovery of their lungs.
The Risks if a Collapsed Lung Doesn’t Heal Properly
Ignoring symptoms or delaying treatment risks serious complications:
- Pneumonia: Fluid buildup around damaged lungs invites infection.
- Pleural effusion: Excess fluid accumulation makes breathing harder.
- Lung scarring: Permanent damage reduces respiratory capacity long-term.
- Tension pneumothorax development: Untreated small leaks can progress dangerously fast.
- Lung collapse recurrence: Incomplete healing increases chances future episodes happen again.
Prompt diagnosis and following medical advice are crucial for avoiding these outcomes and ensuring your lungs recover fully after collapse events.
The Role of Imaging in Tracking Lung Recovery
Chest X-rays remain standard tools for confirming if a collapsed lung has re-expanded properly after treatment begins. They show how much air remains outside your lungs and help doctors decide whether tubes can be removed safely.
CT scans provide more detailed views when complications arise or initial X-rays aren’t conclusive enough about healing status.
Serial imaging over days or weeks tracks gradual absorption of trapped air until full resolution occurs.

Frequently Asked Questions
Do collapsed lungs heal naturally without treatment?
Yes, some collapsed lungs can heal naturally, especially small spontaneous pneumothoraxes. The trapped air is gradually absorbed by the body, allowing the lung to re-expand over days to weeks. However, medical evaluation is essential to ensure proper healing and avoid complications.
How does the severity of a collapsed lung affect its healing?
The severity greatly influences healing time and treatment needs. Mild cases often resolve on their own, while severe or tension pneumothorax requires urgent medical intervention. Delayed or inadequate care can lead to longer recovery or serious complications.
Can a collapsed lung caused by trauma fully heal?
A traumatic collapsed lung can heal fully if treated promptly and properly. Healing depends on injury extent and whether complications like infection occur. Surgical procedures or chest tube placement may be necessary to support recovery.
What factors influence how quickly collapsed lungs heal?
Healing speed depends on the type of pneumothorax, underlying lung health, and timely medical care. Primary spontaneous pneumothorax in healthy individuals often heals faster than secondary types linked to lung diseases. Prompt treatment improves outcomes significantly.
Is emergency treatment always required for collapsed lungs to heal?
Not always. Small spontaneous collapses might heal without emergency care, but tension pneumothorax is life-threatening and demands immediate intervention to relieve pressure. Early diagnosis and treatment are critical for safe and effective healing.
The Bottom Line – Do Collapsed Lungs Heal?
Yes — collapsed lungs do heal in most cases either naturally or with proper medical intervention. Small spontaneous collapses often recover on their own within one to two weeks as trapped air slowly absorbs back into tissues under oxygen support and observation.
More serious cases need needle aspiration, chest tube drainage, or even surgery for complete recovery which might take several additional weeks depending on individual factors.
Ignoring symptoms risks dangerous complications including persistent leaks that won’t heal properly without aggressive treatments.
Following medical advice carefully combined with healthy lifestyle choices greatly improves chances your lungs will bounce back fully.
So if you’re wondering “Do collapsed lungs heal?” — rest assured they usually do when treated promptly and carefully monitored throughout recovery.
