In rare cases, pneumomediastinum may also arise as a result of blunt chest trauma (e.g. car accidents, fights, over pressure of breathing apparatus), while still evolving in the same fashion as the spontaneous form. [13] Pneumomediastinum is most commonly seen in otherwise healthy young male patients and may not be prefaced by a relevant ...
Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema.
The double bronchial wall sign is best visualized on CT, which provides high-resolution images of the mediastinal structures. The double bronchial wall sign is commonly seen in the central bronchi, particularly in the trachea or mainstem bronchi, where air is more likely to outline the structures.
Unstable patients are managed by operative exploration of the mediastinum. Moribund patients go through an emergency department thoracotomy . This measure is taken because at their arrival in the emergency room, these patients are in such critical condition that they would not survive long enough to be transferred to an operating room.
Pneumomediastinum can result from a number of events. For example, foreign body aspiration, in which someone inhales an object, can cause pneumomediastinum (and lead to subcutaneous emphysema) by puncturing the airways or by increasing the pressure in the affected lung(s) enough to cause them to burst.

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 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.
An admission form is a fundamental record in nursing documentation. It documents a client's status, reasons why the client is being admitted, and the initial instructions for that client's care. [3] The form is completed by a nurse when a client is admitted to a health care facility.
