These findings regarding the frequency of cardiac arrests in schools and senior centers are generally consistent with other studies.
In theory, you want to put the defibrillators in places like senior centers where there are more cardiac arrests. Instead, we saw more defibrillators in schools. This practice may not be maximizing the numbers of lives that could be saved.
Thus, intuitively, we would expect that there would be more defibrillators in senior centers than in schools.
