Spontaneous pneumomediastinum may sound complicated, but it’s essentially a condition where air leaks into the space between the lungs. It can be frightening, but understanding its causes, symptoms, and treatment options can help ease worries and ensure timely medical attention.
Spontaneous pneumomediastinum occurs when air escapes from the lungs and enters the mediastinum, the space in the chest between the two lungs. This air can accumulate and cause various symptoms, ranging from mild discomfort to severe respiratory distress.
Types:
There are generally two types of spontaneous pneumomediastinum: primary and secondary. Primary spontaneous pneumomediastinum happens without any underlying lung disease or trauma. Secondary spontaneous pneumomediastinum occurs as a result of an underlying lung condition or trauma.
Causes:
- Asthma exacerbation
- Chronic obstructive pulmonary disease (COPD)
- Smoking
- Forceful vomiting
- Strenuous physical activity
- Severe coughing spells
- Use of illicit drugs, particularly cocaine
- Esophageal rupture (Boerhaave syndrome)
- Blunt trauma to the chest
- Penetrating chest injuries
- Infections such as pneumonia
- Lung cysts or blebs rupture
- Barotrauma (sudden changes in air pressure)
- Invasive medical procedures like intubation
- Inhalation of foreign objects
- Connective tissue disorders like Marfan syndrome
- Certain medications causing airway irritation
- Radiation therapy to the chest
- Boating or diving accidents leading to pressure changes
- Severe vomiting due to eating disorders
Symptoms:
- Chest pain, often sharp or stabbing
- Shortness of breath or difficulty breathing
- Feeling of pressure in the chest
- Subcutaneous emphysema (crackling sensation under the skin)
- Hoarse voice or difficulty speaking
- Swollen neck or face
- Rapid heart rate (tachycardia)
- Dizziness or lightheadedness
- Bluish discoloration of the skin (cyanosis)
- Fatigue or weakness
- Dry cough
- Difficulty swallowing (dysphagia)
- Abdominal pain
- Nausea or vomiting
- Fever or chills if caused by infection
- Wheezing sounds during breathing
- Increased respiratory rate (tachypnea)
- Anxiety or panic attacks
- Reduced breath sounds on examination
- Decreased oxygen saturation levels
Diagnostic Tests
(History, Physical Examinations):
- Medical history review: The doctor will ask about your symptoms, medical history, and recent activities that may have triggered the condition.
- Physical examination: The doctor will examine your chest for signs of subcutaneous emphysema, listen to your breathing, and check for any abnormalities.
- Chest X-ray: A chest X-ray can show air in the mediastinum or any underlying lung conditions.
- Computed tomography (CT) scan: CT scans provide detailed images of the chest, helping to identify the extent and location of air leakage.
- Arterial blood gas (ABG) test: This test measures the levels of oxygen and carbon dioxide in your blood, indicating how well your lungs are functioning.
- Bronchoscopy: A flexible tube with a camera is inserted into the airways to visualize any abnormalities or sources of air leakage.
- Echocardiogram: This ultrasound of the heart can rule out any cardiac issues contributing to symptoms.
- Pulmonary function tests: These tests assess lung function and can identify any underlying lung diseases.
- Magnetic resonance imaging (MRI): MRI scans can provide detailed images of the chest, particularly useful if CT scans are inconclusive or to assess soft tissue structures.
- Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart, ruling out cardiac causes of chest pain.
- Blood tests: Blood tests may be conducted to check for signs of infection or other abnormalities.
- Lung ultrasound: This non-invasive imaging technique can detect pneumomediastinum and assess lung sliding.
- Pleural fluid analysis: If there is suspicion of infection, fluid from around the lungs may be sampled and analyzed.
- Esophagram: A contrast dye is swallowed, and X-rays are taken to visualize the esophagus and detect any leaks.
- Thoracentesis: If there’s a suspicion of fluid accumulation around the lungs, a needle may be inserted to drain the fluid for analysis.
- Nasopharyngoscopy: A small camera is inserted through the nose to examine the upper airway for any abnormalities.
- Lung biopsy: In rare cases, a sample of lung tissue may be taken for analysis to determine the underlying cause.
- Radionuclide scanning: This imaging technique can detect air leakage and assess lung perfusion.
- Thoracic ultrasound: This can be used to assess lung sliding and detect pneumothorax, a related condition.
- Exhaled nitric oxide test: This test measures the levels of nitric oxide in exhaled breath, which can be elevated in certain respiratory conditions.
Treatments
(Non-Pharmacological):
- Observation: In mild cases, observation in a medical setting may be all that’s required as spontaneous pneumomediastinum often resolves on its own.
- Oxygen therapy: Supplemental oxygen can help alleviate symptoms and improve oxygenation in more severe cases.
- Rest and avoidance of strenuous activities: Resting and avoiding activities that may exacerbate symptoms can aid recovery.
- Avoiding smoking and illicit drugs: Quitting smoking and avoiding illicit drugs can prevent further damage to the lungs and reduce the risk of recurrence.

- Humidified air: Breathing humidified air can soothe the airways and reduce irritation.
- Positioning: Sitting upright or adopting certain positions can help relieve pressure on the chest and aid breathing.
- Soft diet: A soft diet may be recommended to reduce the risk of further esophageal injury in cases of Boerhaave syndrome.
- Speech therapy: In cases where hoarseness or difficulty speaking persists, speech therapy may be beneficial.
- Stress reduction techniques: Stress management techniques such as mindfulness and relaxation exercises can help alleviate anxiety and panic attacks associated with the condition.
- Diet modifications: Avoiding foods that trigger acid reflux or gastrointestinal issues can help prevent exacerbations.

- Physiotherapy: Regular physiotherapy sessions can help improve respiratory muscle strength and overall lung function.
- Breathing exercises: Techniques such as pursed-lip breathing and diaphragmatic breathing can help improve oxygenation and reduce breathlessness.
- Airway clearance techniques: Devices such as incentive spirometers or positive expiratory pressure devices can assist in clearing mucus from the airways.
- Heat therapy: Applying heat packs or warm compresses to the chest can help alleviate chest pain and discomfort.
- Cold therapy: Cold packs or ice packs applied to the neck or chest can help reduce swelling and inflammation.
- Postural adjustments: Adjusting body positioning to promote optimal lung expansion and airflow can improve breathing efficiency.
- Inspiratory muscle training: Using devices like a respiratory muscle trainer can strengthen the muscles involved in breathing.
- Relaxation techniques: Practices such as meditation, yoga, or tai chi can help reduce stress and promote relaxation, which may alleviate symptoms.
- Energy conservation strategies: Pacing activities and conserving energy can prevent fatigue and optimize daily functioning.
- Supportive care: Providing emotional support and encouragement to patients can improve their overall well-being and resilience during treatment.
