The objective of this study was to investigate how rapidly the Emergency Medical System provides life support to patients suffering out-of-hospital cardiac arrest in Milan, Italy. The study population included 1426 consecutive participants with out-of-hospital cardiac arrest between January 2007 and October 2008. The mean age was 72.7 years. The incidence of ventricular tachycardia/ventricular fibrillation as the presenting rhythm was 12.7%. Eighty percent of out-of-hospital cardiac arrests occurred at home and bystander cardiopulmonary resuscitation (CPR) was in progress in 11.1% of all cases. The mean time interval from collapse-to-first shock was 18.67±5.37 min. The mean Emergency Medical System unit response time interval was 7.07±3.14 min; time elapsed from arrival-to-first CPR was 7.75±4.32 min. In conclusions, the dispatch to arrival and dispatch to CPR intervals are comparable with those reported in other large urban areas, but the time from arrival-to-first CPR was longer than recommended by current guidelines.

Abstract
The objective of this study was to investigate how rapidly the Emergency Medical System provides life support to patients suffering out-of-hospital cardiac arrest in Milan, Italy. The study population included 1426 consecutive participants with out-of-hospital cardiac arrest between January 2007 and October 2008. The mean age was 72.7 years. The incidence of ventricular tachycardia/ventricular fibrillation as the presenting rhythm was 12.7%. Eighty percent of out-of-hospital cardiac arrests occurred at home and bystander cardiopulmonary resuscitation (CPR) was in progress in 11.1% of all cases. The mean time interval from collapse-to-first shock was 18.67±5.37 min. The mean Emergency Medical System unit response time interval was 7.07±3.14 min; time elapsed from arrival-to-first CPR was 7.75±4.32 min. In conclusions, the dispatch to arrival and dispatch to CPR intervals are comparable with those reported in other large urban areas, but the time from arrival-to-first CPR was longer than recommended by current guidelines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
