Clinical Performance Summary
13-20 Specifications & Safety
7DEOH&OLQLFDO6XPPDU\
Conclusion
The 150J SMART Biphasic waveform defibrillated at higher rates than 200-
360J monophasic waveforms, resulting in more patients achieving return of
spontaneous circulation (ROSC) (p=0.01). EMS system outcomes of survival
discharge were not significantly different statistically. However, patients
resuscitated with the lower energy SMART Biphasic waveform were more
likely to have good cerebral performance (CPC, cerebral performance cate-
gory) (p=0.04).
