A total of 2,458 New Zealanders experienced an out-of-hospital cardiac arrest (OHCA) in 2022/23, up from 2,212 in 2019/20—an increase of 11 percent over the four years. And despite bystanders doing CPR in 76 percent of cases, only 11 percent of victims survive 30 days after they’re discharged from hospital, down from 14 percent in 2018/19.
That’s despite 23 percent of people being successfully revived by CPR—a statistic called “return of spontaneous circulation (ROSC) sustained to hospital handover.”
