Influence of pre-CPR conditions on EMS response times in circulatory arrest. The Cerebral Resuscitation Study Group.
Several time intervals, with important influence on the outcome of CA and CPR, are determined by the local EMS-MICU characteristics: time to introduction in the EMS, response time of BLS, duration of BLS before ALS. These time factors have been studied in 2779 out-of-hospital CA cases, treated by the MICU in teams of 7 major Belgian hospitals. The analysis compares the time intervals in the following pre-CPR conditions: the age of the patient; the previous health status of the patient; the disease underlying the CA; the site where CA occurs; the witnessing of the CA; the type of CA; the MICU center, responding to the CA. The mean introduction time is 4.6 min, the mean response time of BLS is 5.1 min, the mean duration of BLS before ALS is 11 min. Introduction in EMS should be improved in CA due to intoxication, drowning, SIDS and respiratory disease, and overall when CA occurs at home.
