Pathophysiology
Clinical meaning
Cardiac tamponade occurs when pericardial fluid accumulates faster than the pericardium can stretch, raising intrapericardial pressure above right atrial and then right ventricular diastolic pressure. This external compression collapses the right-sided chambers during diastole, severely reducing ventricular filling and cardiac output. Connect Cardiac Tamponade Management to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
