CPR, cardiopulmonary resuscitation. Subjects were excluded if they reported CPR training within the past 2 yrs (see Methods for full set of inclusion and exclusion criteria); prior CPR training was not assessed in our brief screening process but only collected after enrollment. p values represent statistical comparison between the standard and continuous chest compressions groups.
