Bakground :
@EN Dispatcher-assisted telephone instruction in cardiopuimonary resuscitation (CPR) has been proposed to increase rates of bystander CPR in cases of out-of-hospital cardiac arrest. In Korea, bystanders do not know how they resuscitate the
victims
and
EMS (Emergency Medical System) is incomplete.
@ES Study Objectives :
@EN This study was undertaken to tested the efficacy of dispatcher assisted telephone CPR using a recording mannikin (Anne Resusci) in a highstress, simulated cardiac arrest scenario.
@EN Study Subjects :
@EN We assesed in a group of volunteers, without prior CPR lectured and training (Group I, n=20), without prtor CPR training but received lecture previously (Group II, n=20) who received telephone instruction were compared with that of previously
recevied lecture and tranined (Group III, n=20) who received same massage. Performances of above groups were also compared with a group (Group IV, n=20) composed of previously received lecture and trained volunteers who did not receive the
massage.
@ES Results :
@EN Members of groups I. II, and III delivered similar average ventilation volumes, approximately lL/cycle. In contrast, group IV delivered somewhat less, about 700ml/cycle (p<0.05). Group I performed ventilation better than group IV but there
was
no
significant intergroup differences in the performing effective chest compressions. The global performance of group III, the group with prior CPR lecture, trained and telephone instruction, was superior to that achieved by other groups (P<0.05).
We
conclude that dispatcher-assisted telephone CPR can offer a safe and cost-effective means to increase the rate of bystander CPR and also improves the quality of CPR performed by persons with prior CPR training.
