Traumatic pneumothorax may also be observed in those exposed to blasts, even when there is no apparent injury to the chest. [9] Traumatic pneumothoraces may be classified as "open" or "closed". In an open pneumothorax, there is a passage from the external environment into the pleural space through the chest wall.
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack. [13] [14]
Pneumothorax Condition; A person breathing at rest inhales and exhales approximately half a liter of air during each respiratory cycle, which is called tidal volume. The respiratory rate is directly affected by the concentration of carbon dioxide in the blood. Lungs do not collapse after forceful respiration because of the residual volume.
If 'transpulmonary pressure' = 0 (alveolar pressure = intrapleural pressure), such as when the lungs are removed from the chest cavity or air enters the intrapleural space (a pneumothorax), the lungs collapse as a result of their inherent elastic recoil. Under physiological conditions the transpulmonary pressure is always positive; intrapleural ...

A thoracostomy is a small incision of the chest wall, [1] with maintenance of the opening for drainage. [2] It is most commonly used for the treatment of a pneumothorax.This is performed by physicians, paramedics, and nurses usually via needle thoracostomy or an incision into the chest wall with the insertion of a thoracostomy tube (chest tube) or with a hemostat and the provider's finger ...
Pneumothorax, emphysema, chronic bronchitis, asthma, severe pneumonia, and aspiration are among the most frequent causes. It can also occur as a compensatory response to chronic metabolic alkalosis. [citation needed]
Thoracic endometriosis is the most common non-abdominal site of involvement and is also the primary risk factor for catamenial pneumothorax. [5] Catamenial pneumothorax is the primary clinical presentation of thoracic endometriosis, and is defined as recurrent episodes of lung collapse within 72 hours before or after menstruation.
