Re-establishing blood flow to the vital organs is the single most important factor for successful resuscitation when the duration of cardiac arrest is prolonged beyond four minutes. 

– W. Tang

The 2010 American Heart Association Guidelines mention it early and often—cardiopulmonary resuscitation (CPR). Push harder, push faster, allow full chest recoil, implement better training protocols, minimize interruptions, restore adequate cerebral and coronary blood flow—the list goes on and on, but one fact remains, CPR can be the difference between life and death, and the quality of it is as important as remembering to do it. It is not our goal to teach CPR techniques here, but rather to review the science, explore the research, and provide information about the tools that can help improve CPR by moving more blood and raising coronary perfusion pressure to ultimately improve outcomes.
