2.1. CARDIAC TAMPONADE

Causes of cardiac compression (tamponade) may include hemorrhages from The Heart chambers into the pericardial cavity due to injuries or cardiac rupture resulting from transmural infarction, injuries to pericardial vessels or coronary vessels. The Development of cardiac tamponade with a small pericardial wound is associated with its occlusion by a Blood clot or a foreign body. These factors impede the outflow of blood from the pericardial sac outward or into the pleural cavity. In turn, the progressive accumulation of blood leads to impaired Cardiac Activity up to cardiac arrest. The latter typically occurs when the pressure in the pericardial cavity exceeds 27 mm H2O, which corresponds to an accumulation of blood (Hemopericardium) exceeding 200 ml.
