Bystander CPR with at least a shock by AED increases survival rate

London Ambulance Service published a report that shows the proportion of people surviving a cardiac arrest that happens outside of hospital reaching its highest level of 10.8 per cent – twice the rate it was a decade ago.

“10,152 patients suffered an out-of-hospital cardiac arrest between 1st April 2018 to 31st March 2019 and our clinicians attempted to resuscitate 4,004 (39.4%) of these patients. Resuscitation efforts were not undertaken for 6,148 (60.6%), with 4,386 of these patients being recognised as deceased on arrival of the clinician, and the remaining 1,762 had in place a Do Not Attempt Cardio-Pulmonary Resuscitation (DNA-CPR) order, advanced directive or equivalent, or the patient’s death was expected.” it reports

AED increases survival rate

Interestingly for casualties with an AED was deployed, with one or more shocks being delivered, 79.5% had ROSC (return of spontaneous circulation) sustained to hospital (14.9% increase from last year). Survival to hospital discharge was 57.1% – an increase of 5.8% compared to last year (51.3%).
