In-Hospital Cardiac Arrest: The First 15 Minutes

Background: Over the past few years there has been a shift in cardiac arrest from the mantra of ABC (Airway, Breathing, Circulation) to CAB (Circulation, Airway, Breathing).  There has been increased emphasis on circulation and a de-emphasis of airway management in cardiac arrest.  Physiologically, this makes sense as the only two interventions in cardiac arrest that have been shown to make a difference in neurological outcomes are early, high quality CPR and defibrillation.  The reason for this is increased coronary and cerebral perfusion pressure, which improve oxygenation to ischemic tissue.  The less ischemic cardiomyocytes are the more likely they will convert to a perfusing rhythm.  Similarly, the less ischemic neurons are, the more likely we will have a better neurologic outcome for our patients.  It has been fairly well established in the peer reviewed literature that advanced airway management in the prehospital setting is associated with decreased survival with good neurologic outcome.  There is considerably less literature exploring this area in in-hospital cardiac arrest.
