b'2024 DATASETReturn of spontaneous circulation (ROSC) in the field, survival to hospital admission, and survival to hospital discharge were all strongly associated with receipt of bystander CPR (Figure 14). The survival to discharge rate for patients receiving bystander CPR (13.0%) was significantly higher (p.0001) than that of patients who did not receive bystander CPR (7.6%).Figure 14.
