The main symptom is usually severe central chest pain. Other symptoms include laboured breathing, voice distortion (as with helium) and subcutaneous emphysema, specifically affecting the face, neck, and chest. [4] Pneumomediastinum can also be characterized by the shortness of breath that is typical of a respiratory system problem.
Air in subcutaneous tissue does not usually pose a lethal threat; [4] small amounts of air are reabsorbed by the body. [8] Once the pneumothorax or pneumomediastinum that causes the subcutaneous emphysema is resolved, with or without medical intervention, the subcutaneous emphysema will usually clear. [18]
Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
While many causes of lower left abdominal pain can be managed at home through lifestyle changes and over-the-counter remedies, persistent or severe symptoms require professional medical evaluation ...
Hamman's syndrome, also known as Macklin's syndrome, is a syndrome of spontaneous subcutaneous emphysema [1] (air in the subcutaneous tissues of the skin) and pneumomediastinum (air in the mediastinum, the center of the chest cavity), sometimes associated with pain and, less commonly, dyspnea (difficulty breathing), dysphonia, and a low-grade fever.
Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity. The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. Pneumatosis intestinalis, air or gas cysts in the bowel wall; Gastric ...
Hamman's crunch is caused by pneumomediastinum or pneumopericardium, and is associated with tracheobronchial injury [6] due to trauma, medical procedures (e.g., bronchoscopy) or rupture of a proximal pulmonary bleb. It can be seen with Boerhaave syndrome.
Common symptoms are often flulike and include headache, dizziness, upset stomach, chest pain or confusion, but highly concentrated levels of CO can cause a person to pass out without feeling symptoms.
