The most common findings in people with tension pneumothorax are chest pain and respiratory distress, often with an increased heart rate (tachycardia) and rapid breathing in the initial stages. Other findings may include quieter breath sounds on one side of the chest, low oxygen levels and blood pressure , and displacement of the trachea away ...
The most common cause of tracheal deviation is a pneumothorax, which is a collection of air inside the chest, between the chest cavity and the lung. A pneumothorax can be spontaneous, caused by existing lung disease, or by trauma. Treatment varies, depending on the severity of the pneumothorax.
Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax. Other causes include abdominal compartment syndrome, Hiatal hernia, severe aortic valve stenosis, and disorders of the aorta. Constrictive pericarditis is a rare cause.
Subcutaneous emphysema can be caused by medical procedures and medical conditions that cause the pressure in the alveoli of the lung to be higher than that in the tissues outside of them. [4] Its most common causes are pneumothorax or a chest tube that has become occluded by a blood clot or fibrinous material.
The most common cause is injury to the chest from blunt force or surgery on the heart or chest. Hemothorax also can occur in people with lung or pleural cancer. Hemothorax can put pressure on the lung and force it to collapse. It also can cause shock, a state of hypoperfusion in which an insufficient amount of blood is able to reach the organs.
Many different conditions can lead to the feeling of dyspnea (shortness of breath). DiagnosisPro, an online medical expert system, listed 497 in October 2010. [1] The most common cardiovascular causes are acute myocardial infarction and congestive heart failure while common pulmonary causes include: chronic obstructive pulmonary disease, asthma, pneumothorax, and pneumonia.
While hemorrhage is the most common cause of shock in the trauma patient, other causes of shock are to remain on the differential. Obstructive shock can occur in the setting of tension pneumothorax and cardiac tamponade. These etiologies should be uncovered in the primary survey. [3]
The most common tracheal injury is a tear near the carina or in the membranous wall of the trachea. [15] In blunt chest trauma, TBI occurs within 2.5 cm of the carina 40–80% of the time. [2] The injury is more common in the right main bronchus than the left, possibly because the former is near vertebrae, which may injure it. [2]
