Cardiac arrest & resuscitation
Compliance with cardiopulmonary resuscitation (CPR) quality guidelines and survival after 30 days following out‐of‐hospital cardiac arrest. A retrospective study
Authors' conclusion
Patients who suffered out-of-hospital cardiac arrest in Southern Ostrobothnia received CPR that met the international CPR quality target values. The proportion of unintentional pauses during CPR was low and the 30-day survival rate exceeded the international average.
