Effect of selective intra-aortic volume expansion in CPP during prolonged ventricular fibrillation

Abstract

Background: Coronary perfusion pressure (CPP) is a valuable predictor of return of spontaneous circulation. In refractory cardiac arrest, CPP is usually inadequate. Resuscitative efforts based solely on external chest compression may be limited in their ability to generate adequate CPP. The aim of this study is to investigate the effect of selective intra-aortic volume expansion in CPP during prolonged ventricular fibrillation (VF).
