A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily.

A pneumothorax is an abnormal collection of air in the pleural space that causes an uncoupling of the lung from the chest wall. Like a pleural effusion (liquid buildup in that space), a pneumothorax may interfere with normal breathing. Symptoms typically include chest pain and shortness of breath.

The Children's Hospital of Philadelphia. A spontaneous pneumothorax is the sudden onset of a collapsed lung without any apparent cause, such as a traumatic injury to the chest or a known lung disease. A collapsed lung is caused by the collection of air in the space around the lungs.

The most common findings in people with tension pneumothorax are chest pain and respiratory distress, often with an increased heart rate (tachycardia) and rapid breathing (tachypnea) in the initial stages.

Other risk factors include connective tissue disorders, smoking, and activities such as scuba diving, high altitudes and flying. Spontaneous pneumothorax most commonly presents without severe symptoms. Patients with a collapsed lung may experience a sudden onset of the following symptoms: 1  Sharp chest pain, made worse by a deep breath or a cough.  Shortness of breath.

Pneumothorax is the collection of air or gas in the space inside the chest around the lungs, which leads to a lung collapse. This article discusses pneumothorax in infants.

This is a chest x-ray of a patient with a collapsed lung. The image shows a large right-sided pneumothorax, caused by a collection of air in the space around the lung. This image shows a chest tube placed between the ribs, one treatment option for patients with large pneumothorax and severe symptoms.

In a minority of cases the amount of air in the chest increases markedly when a one-way valve is formed by an area of damaged tissue, leading to a tension pneumothorax. This condition can cause a steadily worsening oxygen shortage and low blood pressure. Unless reversed by effective treatment, it can result in death.

In a larger pneumothorax, or when there are marked symptoms, the air may be removed with a syringe or a chest tube connected to a one-way valve system. Occasionally, surgery may be required if tube drainage is unsuccessful, or as a preventive measure, if there have been repeated episodes.
