Abstract

Cardiac tamponade is characterized by increased pressure in the pericardial space and can significantly impair circulation. Differentiation between pericardial effusion and the critical condition of tamponade requires an understanding of the underlying physiology, as simple pericardial effusion—the accumulation of excess fluid— does not always lead to the development of tamponade. Hemodynamic and echocardiographic evaluations can guide clinical decision making to ensure proper management of these patients. With clear comprehension of these distinctions, clinicians can quickly identify and address cardiac tamponade, ensuring optimal patient outcomes.
