APPENDICES
On/Off button A green button located on the front of the HeartStart FRx Defibrillator. Pressing
the On/Off button when the defibrillator is in standby m ode turns the defibrillator
on; pressing and holding the On/Off button for one second when the defibrillator
is on turns the defibrillator off and disarms the defibrillator. In addition, pressing
the On/Off button stops the battery insertion self-test that automatically runs
when a battery is inserted.
pads See “SMART Pads II.”
patient care pause A defined period to allow CPR. See “NSA pause” and “protocol pause.”
periodic self-tests Daily, weekly, and monthly tests automatically conducted by the HeartStart FRx
Defibrillator when it is in its standby mode. The test s monitor many key functions
and parameters of the defibrillator, including battery capacity, pads readiness, and
the state of its internal circuitry.
protocol A sequence of operations performed by the HeartStart FRx Defibrillator to direct
patient care in the AED mode.
protocol pause A period provided by the HeartStart FRx Defibrillator after a shock series, during
which the responder can administer CPR. The de fibrillator does not conduct
background monitoring of the patient’s heart rhythm during this pause.
Quick Shock The ability of th e FRx to deliver a defibrillation shock very q uickly – typically
within 8 seconds – after the end of a patient care pau se.
Ready light A green LED showing the readiness for use of the Hea rtStart FRx Defibrillator.
A blinking Ready light means the defibrillator is ready for use; a solid Ready light
means the defibrillator is being used.
rhythm analysis See “SMART analysis.”
Shock button An orange button with a lightning bolt symbol on it, located on the front of the
HeartStart FRx Defibrillator. The Shock button flashes when a shock is advised.
You must press the button for the shock to be delivered.
shockable rhythm A heart rhythm that the HeartStart FRx Defibrillator determines is appropriate
for defibrillation, such as ventricular fibrillation and s ome ventricular tachycardias
associated with sudden cardiac arrest.
SMART analysis The proprietar y algorithm used by the HeartSta rt FRx Defibrillator to analyze the
patient’s heart rhythm and determine whether a shock is advised.
SMART biphasic
waveform
The patented, low-energy defibrillati on shock waveform used by the HeartStart
FRx Defibrillator. It is an impedance-compensated biphasic waveform. It delivers
150 Joules, nominal, into a 50 ohm load; when the Infant/Child Key is inserted, it
delivers 50 Joules, nominal, into a 50 ohm load.
