The article reviews Community-Based
CPR in Seattle and surrounds. During the previous 9 years,
more than 175,000 residents of Seattle had received basic
CPR training. In one year, 43% of patients (47/109) found
in a state of ventricular fibrillation survived to hospital
discharge when bystanders initiated CPR. By comparison,
only 21% (43/207) lived when CPR was delayed until fire
department personnel arrived on the scene (p<.001).
There was little influence of bystander-initiated CPR on
the rate of immediate resuscitation (67% with bystanders
vs. 61% in the others), importantly however, hospital mortality
in resuscitated patients was halved if bystanders had initiated
CPR. As well, at the time of hospital admission, half of
the patients who had received bystander CPR showed at least
some form of conscious behaviour. In contrast, only 6%
of patients for whom resuscitation had been delayed until
the arrival of the fire department showed such responses.
Similarly, there was significantly less neurologic impairment
at discharge. It is important to emphasize however, that
citizen-initiated CPR is a temporizing measure, only one
of many links in the EMS chain. In the Seattle experience
for example, initial fire department response averages
3 minutes with secondary ALS response of 5-6 minutes. As
such, the duration of citizen CPR is generally but a few
minutes. It is the author's position that virtually everyone
of high-school age and older should be taught when and
how to perform CPR. With continued early application of
CPR and more rapid deployment of advanced life support
measures, it seems possible that a survival rate approaching
50% in patients with ventricular fibrillation can be obtained
in some urban communities.
