  • Assumes total US population is 321 716 000.7 CI indicates confidence interval; EMS, emergency medical services; LCL, lower confidence limit; UCL, upper confidence limit; and VF, ventricular fibrillation.

  • * The estimated number of annual VF cases of any age is less than the estimated number of cases in adults alone because of rounding and missing information about patient age.

  • Source: Resuscitation Outcomes Consortium Investigators, unpublished data, data time frame is June 1, 2014, to May 31, 2015. Population growth of 0.93% per year has now been added from the 2010 population. In 2013, 23.27% of population was <18 years of age. This is used for annual number of case estimates for adults and children.
