Aim To describe changes in rate of CPR, Compression Only CPR (CO-CPR), and 30–day survival over 3 different time-periods of CPR guidelines in Sweden. We hypothesised that increased use of CO-CPR would be associated with increased CPR-rates and similar survival compared to standard CPR.

Methods Registry based cohort study including all bystander witnessed cases of out-of-hospital cardiac arrests reported to the Swedish register for cardio-pulmonary resuscitation in 2000–2014. Exposure was categorised as bystander CPR or No-CPR. Bystander CPR was further categorised into Standard CPR with rescue breathing and ventilation (S-CPR) or CO-CPR. Primary outcome was 30 day survival.

Results 23620 patients were included. Total rates of bystander CPR increased from 36% in 2000 to 68% in 2014. S-CPR increased from 31% in 2000 to 38% in 2014. CO-CPR increased from 5% in 2000 to 30% 2014. Overall, there was no significant difference in survival among patients receiving CO-CPR or S-CPR (13.6% vs. 12.9% p=0.3).

Conclusion Increase in bystander CPR during the last 15 years in Sweden was associated with an increase in CO-CPR. Overall 30 day survival was not different when comparing CO-CPR to S-CPR.
