Overview
A rapid beside echocardiogram can identify several rapidly reversible causes of PEA such as cardiac tamponade, myocardial infarction, cardiac rupture and underfilling of the ventricle due to hypovolemia. Elevated right heart filling pressures suggest pulmonary embolism. Tension pneumothorax can also be observed on a bedside echocardiogram
Echocardiography
A rapid beside echocardiogram can identify several rapidly reversible causes of PEA such as cardiac tamponade, myocardial infarction, cardiac rupture and underfilling of the ventricle due to hypovolemia. Elevated right heart filling pressures suggest pulmonary embolism. Tension pneumothorax can also be observed on a bedside echocardiogram[1]. PEA underlying causes are separated into primary and secondary forms. The secondary form includes the causes that result from an abrupt cessation of cardiac venous return, such as massive pulmonary embolism, acute malfunction of prosthetic valves, exsanguinations, and cardiac tamponade. Echocardiography during CPR is beneficial to detect secondary causes that include easily treatable, reversible pathologies associated with PEA
