Adult survival from shockable rhythms

chance of survival from OHCA. Ten year outcomes for patients with shockable rhythms have
demonstrated favourable findings in 2011/12, with 52% of patients surviving to hospital and
30% surviving to hospital discharge. This result is significantly higher than those observed in
2002/03, where survival was 32% and 10% respectively.
