  • Secondary pneumothorax, defined as pneumothorax occurring in the setting of acute trauma (including iatrogenic) or underlying lung disease including but not limited to COPD, pulmonary fibrosis, TB, cystic fibrosis, lung cancer and asthma that requires regular preventative medication or has been symptomatic within the last two years 2. Previous spontaneous pneumothorax on the same side 3. Coexistent haemothorax (i.e. spontaneous haemopneumothorax) 4. Bilateral pneumothorax 5. Clinical instability suggesting tension pneumothorax; respiratory distress persisting despite oxygen and parenteral narcotic analgesia (RR >30/min or SpO2 <90%), SBP <90 mmHg, HR greater than or equal to SBP. 6. Pregnancy at time of enrolment 7. Social circumstances whereby the patient either does not have adequate support after discharge to re-attend hospital if required, or is unlikely to present for study follow up. 8. Air travel within the next 12 weeks if this cannot be deferred should the pneumothorax be slow to resolve
