Blunt or penetrating trauma that causes bleeding into the tough sac that surrounds the heart is called?

Sagot :

Pericardial tamponade.

Blunt or penetrating trauma may cause bleeding into the tough fibrous sac that surrounds the​ heart, the pericardial sac. Since this sac cannot expand outward very much with the filling​ blood, the result is inward compression of the heart. This is known as cardiac tamponade or pericardial tamponade. The compression of the ventricles prevents adequate ventricular​ filling, leading to a reduction in​ preload, stroke​ volume, and cardiac output. A reduction in cardiac output leads to hypotension. A pulmonary contusion is bleeding within the lung tissue. With a​ hemothorax, the thoracic cavity is filled with blood rather than air.
