What is a pneumothorax?

The pleura are two thin layers: one covers the lung and the other lines the inside of the chest. Air entering the space between them allows the lung to pull inward. The collapse may involve part or most of a lung.

This is different from pleural effusion, where fluid collects around the lung. The term "collapsed lung" is sometimes also used for other conditions, so ask what the scan report means in your case.

What causes a collapsed lung?

Smoking increases risk. A spontaneous pneumothorax can happen at rest, so it does not necessarily mean that exercise caused it. Repeated episodes or a family history may lead the specialist to consider additional investigations.

Symptoms and tension pneumothorax

Typical symptoms include sudden sharp pain on one side of the chest and breathlessness. Pain may be worse with a deep breath. Symptoms vary; a person with existing lung disease may be significantly affected by a smaller pneumothorax.

Tension pneumothorax is a dangerous pressure buildup that interferes with breathing and circulation. It describes the physiological effects, not simply a large area on an X-ray. An unstable patient may need immediate emergency treatment before imaging. This is a hospital emergency, not a condition for self-treatment.

How is pneumothorax diagnosed?

Assessment usually includes the history, examination and chest imaging. A chest X-ray commonly identifies the air around the lung. Ultrasound can help in trained hands, while CT may be useful when findings are unclear, the situation is complex or an underlying cause needs investigation.

Symptoms alone do not distinguish pneumothorax from other serious causes of chest pain or breathlessness, including a blood clot in the lungs. Do not use improvement in pain as evidence that it is safe to delay assessment.

Does every pneumothorax need a chest drain?

No. The team considers how you feel, your vital signs, underlying lung disease, imaging and whether close follow-up is practical. Suitable options should be discussed with you.

Management after trauma, procedures or with underlying lung disease may differ. A treatment pathway offered to one patient may not be suitable for another.

What happens if I need a chest drain?

A trained clinician places a tube through the chest wall into the pleural space using appropriate pain relief. It connects to a drainage system so air can escape and the lung can re-expand. The team monitors comfort, breathing and whether the air leak has stopped.

There is no fixed drain duration or hospital stay for everyone. Removal depends on recovery and evidence that drainage is no longer needed. Tell the team about increasing pain, breathlessness, fever or problems with the tube. Do not disconnect, clamp or adjust a drain yourself.

If discharged with a drainage device, follow the service's written instructions and attend every planned review. A displaced device or worsening symptoms requires urgent assessment.

Can pneumothorax happen again?

Yes. Recurrence is an important part of the follow-up discussion, even after a first episode. Stopping smoking is one of the most useful steps to reduce future risk. The risk for an individual depends on the cause, previous episodes and treatment.

Pleurodesis encourages the pleural layers to stick together, helping prevent air collecting again. It may be performed chemically or as part of surgery. Surgical treatment may also address an area of lung that is leaking.

Not everyone with a secondary pneumothorax automatically needs pleurodesis. Decisions depend on factors such as severity, recurrence, persistent leakage, fitness for surgery and personal priorities. A second episode on the same side or a first episode on the opposite side commonly prompts discussion of surgery.

Recovery, work and exercise

Recovery takes different amounts of time. Keep the agreed review and repeat-imaging appointments even if pain has settled. Some people need review within days; others return over the following weeks. Your discharge plan should state the timing.

Gentle activity can usually be increased as advised once you are clinically stable. Delay strenuous exercise, heavy lifting and contact sport until your treating team confirms that recovery is sufficient. Return to work depends on symptoms, treatment and the demands of the job.

Seek urgent care if chest pain or breathlessness returns. Persistent symptoms may also need review of an underlying lung condition through a respiratory consultation.

When can I fly or go scuba diving?

Air travel

Do not fly with an unresolved pneumothorax. BTS guidance advises waiting at least seven days after a chest X-ray confirms complete resolution. The waiting period starts from confirmed resolution, not from the day the drain was removed. Your clinician or airline may require a longer interval in your circumstances.

Scuba diving

Scuba diving after a spontaneous pneumothorax is generally discouraged permanently unless a sufficiently secure preventive procedure has been performed. Even after surgery, a respiratory and diving-medicine assessment is needed; surgery does not automatically mean clearance to dive.

Respiratory follow-up in Lahore

For review after hospital treatment, Dr G Sarwar Chaudhry assesses respiratory concerns at Australian Polyclinic, DHA Phase 5. Bring the discharge summary, chest X-rays or CT images, reports, procedure details and current medicines.

• Has the pneumothorax fully resolved?
• When is the next scan or review due?
• Is there an underlying lung condition to assess?
• Should recurrence-prevention treatment be discussed?
• When can I return to work, exercise or travel?

The clinic appointment is for planned assessment and follow-up. Suspected acute or recurrent pneumothorax requires urgent hospital evaluation.
