Out-of-hospital cardiac arrest or OHCA is an abrupt loss of cardiac function in a public setting, usually occurring instantly or soon after symptom development (American Heart Association [AHA], 2014-a). Defibrillation and cardiopulmonary resuscitation or CPR are well-documented variables in predicting poor OHCA outcomes (Bur et al. 2001). CPR is the method of compressing a patient’s chest at 100 beats per minute, providing adequate blood flow to the body’s vital organs, preserving life (New Zealand Resuscitation Council, 2010). Defibrillation is the delivery of an electric impulse across the heart to re-establish a normal cardiac rhythm, this is applied with an automated external defibrillator (AHA, 2014b). Return of spontaneous circulation or ROSC is defined as “the presence of a palpable pulse in the absence of ongoing CPR,” meaning that a pulse can be felt (St John, 2015). For the purpose of this essay, the first-aid setting refers to bystander interventions that precede treatment by medical personnel. OHCA is an important topic as in the nine-month period from October 1, 2013, to June 30, 2014, St John (2014) attended 2,740 OHCA events. This essay combines results from peer-reviewed journal articles and the St John (2014) Cardiac Arrest Registry to draw conclusions on the effects of bystander CPR and defibrillation on OHCA outcomes. It will critique the research methods and results, making suggestions for subsequent research that can be done to further the understanding…
