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.
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
If there is a valve mechanism which allows air to enter the skull but prevents it from escaping, a tension pneumocephalus can occur (similar to what can happen in a tension pneumothorax). CT scans of patients with a tension pneumocephalus typically show air that compresses the frontal lobes of the brain, which results in a tented appearance of ...
N 2 O should not be used in patients with bowel obstruction, pneumothorax, or middle ear or sinus disease, [1] or who have had a recent intraocular injection of gas [21] and should also not be used on any patient who has been scuba diving within the preceding 24 hours [22] or in violently disturbed psychiatric patients. [23]
Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury. [12] Cheyne-Stokes respiration may be observed in newborn babies, but this is occasionally physiological (normal). Chest retractions may be observed in patients with asthma.
Left-sided tension pneumothorax. Note the area without lung markings which is air in the pleural space. Also note the tracheal and mediastinal shift from the patient's left to right. Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax.
Traumatic asphyxia, or Perte's syndrome, [1] is a medical emergency caused by an intense compression of the thoracic cavity, causing venous back-flow from the right side of the heart into the veins of the neck and the brain.
Therefore, pneumothorax is usually more of a problem than hemothorax. [8] A pneumothorax may form or be turned into a tension pneumothorax by mechanical ventilation, which may force air out of the tear in the lung. [12] The laceration may also close up by itself, which can cause it to trap blood and potentially form a cyst or hematoma. [8]
