Question

Quizplus · Accepted Answer

The most serious complication of a tension pneumothorax is impaired venous return to the heart, which can result in hypotension, decreased cardiac output, and eventual cardiac arrest. This occurs because the buildup of air in the pleural space causes compression of the lung and the adjacent blood vessels, leading to decreased blood flow to and from the heart. Relaxation atelectasis, pneumomediastinum, and displaced hemidiaphragm are all possible consequences of a tension pneumothorax but are not as immediately life-threatening as impaired venous return.
