A) Cardiac tamponade involves air in the pleural space, while tension pneumo involves fluid around the heart.
B) Cardiac tamponade involves fluid around the heart, while tension pneumo involves air in the pleural space.
C) Cardiac tamponade involves excess fluid in the pericardial sac, while tension pneumo involves pressure on the heart due to trapped air in the pleural space.
D) Cardiac tamponade involves pressure on the heart due to trapped air in the pleural space, while tension pneumo involves excess fluid in the pericardial sac.
