Spontaneous pneumothorax in the elderly

Spontaneous pneumothorax (spontaneous pneumothorax): The pleura is ruptured due to lesions, the pleural cavity communicates with the atmosphere, and the air enters the pleural cavity to form pleural effusion, which is called pneumothorax. Spontaneous pneumothorax in the elderly is mostly secondary to lung or pleural lesions. COPD or diffuse pulmonary fibrosis is often complicated by bullae. When the internal pressure rises sharply, the bullae rupture and pneumothorax occurs. Spontaneous pneumothorax in the elderly is also seen in S. aureus, anaerobic bacteria, or Gram-negative bacilli that cause purulent pneumonia and rupture into the pleural cavity, that is, pneumothorax occurs; pneumothorax can also occur when the lungs or tuberculosis cavities erode the pleura.
