There are approximately 5000 OHCA cases annually in which CPR is started and 30‐day survival is achieved in up to 500 patients yearly (6 per 100 000 inhabitants). Based on findings on survival in relation to the time to calling for the Emergency Medical Service (EMS) and the start of CPR and defibrillation, it was estimated that, if the delay from collapse to (i) calling EMS, (ii) the start of CPR, and (iii) the time to defibrillation were reduced to <2 min, <2 min, and <8 min, respectively, 300–400 additional lives could be saved.</p> </sec> <sec id="joim12041-sec-0008" sec-type="section"> <title>Conclusion</title> <p>Based on findings relating to the delay to calling for the EMS and the start of CPR and defibrillation, we speculate that 300–400 additional OHCA patients yearly (4 per 100 000 inhabitants) could be saved in Sweden.</p> </sec> </abstract>
