Final answer:
Collapsed Jugular vein is not a sign of tension pneumothorax; signs include tracheal deviation, unilateral lung sounds, and cyanosis.
Step-by-step explanation:
The signs and symptoms of a tension pneumothorax include cyanosis, tracheal deviation, and unilateral lung sounds, but not a collapsed Jugular vein. A tension pneumothorax occurs when air enters the pleural space and cannot escape, creating increased pressure that causes the lung to collapse. This condition can result in a number of clinical signs, such as tracheal deviation away from the side of the injury, unilateral absence of breath sounds on the affected side, and cyanosis due to inadequate oxygenation.
However, jugular vein distention rather than collapse would be a sign as the rising pleural pressure can compress the vena cava and lead to increased venous pressure.
A pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall.[3] Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath.
In a minority of cases, a one-way valve is formed by an area of damaged tissue, and the amount of air in the space between chest wall and lungs increases; this is called a tension pneumothorax.
This can cause a steadily worsening oxygen shortage and low blood pressure. This leads to a type of shock called obstructive shock, which can be fatal unless reversed.
Very rarely, both lungs may be affected by a pneumothorax.It is often called a "collapsed lung", although that term may also refer to atelectasis.
