Current treatment recommendations for hyperkalemic cardiac arrest focus exclusively on the addition of antihyperkalemic therapies and are otherwise identical to those for cardiac arrest caused by non-hyperkalemic etiologies. We were unable to find any studies that specifically examine the hemodynamic effects of cardiopulmonary resuscitation in hyperkalemic cardiac arrest compared to cardiac arrest from non-hyperkalemic etiologies. We hypothesized that myocardial ischemic contracture would be less severe in hyperkalemic cardiac arrest compared with ventricular fibrillation cardiac arrest, resulting in higher cerebral perfusion pressure, brain tissue oxygen tension, and coronary perfusion pressure during cardiopulmonary resuscitation.
