The overarching aim of cardiopulmonary resuscitation (CPR) is to generate sufficient myocardial and cerebral blood flow to allow for survival with favorable neurologic outcome.
1.The adequacy of myocardial and cerebral blood flow during CPR depends, in part, on force of chest compressions, rate of compressions, chest compression fraction, and allowing full chest recoil for sufficient venous return.
