Of the more than 300,000 cardiac arrests that occur annually in the United States, survival rates are typically lower than 10% for out-of-hospital events and lower than 20% for in-hospital events. [7, 8, 9, 10, 11] A study by Akahane et al suggested that survival rates may be higher in men but that neurologic outcomes may be better in women of younger age, though the reasons for such sex differences are unclear. [12]

Additionally, studies have shown that survival falls by 10-15% for each minute of cardiac arrest without CPR delivery. [13, 14] Bystander CPR initiated within minutes of the onset of arrest has been shown to improve survival rates 2- to 3-fold, as well as improve neurologic outcomes at 1 month. [15, 16]
