Does subcutaneous emphysema occur when fluid escapes into the chest cavity?

• A. True
• B. False
• C. Only in cases of trauma
• D. Only in cases of disease

Answer: (B)

Subcutaneous emphysema occurs when air, rather than fluid, escapes from a breach in the respiratory system or out of the lung tissue and enters the subcutaneous tissue. This condition can happen due to trauma, such as a punctured lung or chest injury, or spontaneously due to other reasons, but it specifically involves the presence of air rather than fluid in the body tissues. Since the question specifies fluid entering the chest cavity, which typically refers to conditions such as pleural effusion or hemothorax, it does not lead to subcutaneous emphysema. Therefore, the assertion that subcutaneous emphysema occurs when fluid escapes into the chest cavity is not accurate, leading to the conclusion that the correct answer is that this statement is false.
