Resuscitation by laypersons is important in bridging the time between the occurrence of an out-of-hospital cardiac arrest (OHCA) and the arrival of emergency rescue service personnel. Depending on the reason for the cardiac arrest, however, the effectiveness of chest compressions is uncertain. The aim of this study was to explore the impact of lay resuscitation on survival following OHCA of different causes. ⋯ Resuscitation by laypersons is associated with an improved result regarding the endpoint 30 days' survival/discharged alive in cases of OHCA caused by cardiac events and intoxication. These two groups account for 81% of the resuscitation patients in the study. Because there was also a tendency towards higher survival rates following OHCA of other causes (except hypoxia), laypersons should continue to be encouraged to attempt resuscitation in all cases of OHCA, whatever the cause.
