D Glossary of Terms
The terms listed in this Glossary are defined in the context of the HeartStart
FR2+ and its use.
advanced mode ..................... A programmable treatment mode that permits an authorized user to control
when the FR2+ starts rhythm analysis and (model M3860A only) when to
begin defibrillator charging for shock delivery.
AED .......................................... Automated external defibrillator.
AED mode ............................... The standard FR2+ treatment mode, with voice and screen prompts guiding
the responder through connecting the defibrillator pads, waiting for rhythm
analysis, and delivering a shock if needed. In this mode, heart rhythm analysis
and monitoring, and shock decision and charging for shock delivery are
automatically performed by the FR2+.
ALS ........................................... Advanced Life Support.
analysis ................................... See “SMART analysis.”
arrhythmia ............................... An unhealthy, often irregular, beating of the heart.
battery ..................................... See “standard battery” and “rechargeable battery.”
BLS ........................................... Basic Life Support.
continued use ........................ A condition in which use of the HeartStart FR2+ is interrupted for less than
five minutes (e.g., for battery replacement). When the battery is reinserted or
the unit is turned on again, the information stored about the interrupted
incident is saved, any additional events recorded after the battery is
reinstalled are treated as part of the same incident, and the selftest does not
automatically run when the battery is reinstalled.
CPR timer ................................ A programmable period provided by the HeartStart FR2+ during which the
responder can administer CPR.
defibrillation ............................ Termination of cardiac fibrillation by applying electrical energy
defibrillation charge .............. Electrical energy stored in the capacitor of the HeartStart FR2+ as it arms for
shock delivery.
defibrillation shock ................ See “SMART biphasic waveform.”
defibrillator pads .................... The self-adhesive electrode pads applied to the adult patient’s bare chest or
pediatric (under 8 years of age or less than 55 lb./25 kg) patient’s bare chest
and back, and used to detect the patient’s heart rhythm and transfer the
