E-2
Continued Use ............ A condition in which use of the HEARTSTREAM 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 H
EARTSTREAM 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 H
EARTSTREAM FR2 as it arms
for shock delivery.
Defibrillation Pads ..... The self-adhesive electrode pads applied to the patient’s bare chest and used
to detect the patient’s heart rhythm and transfer the defibrillation shock. Only
H
EARTSTREAM defibrillation pads can be used with the FR2.
Defibrillation Shock ... See SMART Biphasic Waveform.
ECG ............................. Electrocardiogram, a display or printout of the electrical rhythm of the heart
as detected through defibrillation electrode pads.
Event ........................... An action recognized or performed by the H
EARTSTREAM FR2 as a step in the
sequence of using the device in an incident. Examples include: applying the
pads and connecting them to the H
EARTSTREAM FR2, analyzing heart rhythm,
delivering a shock, etc.
Fibrillation .................. A disturbance of the normal heart rhythm that results in chaotic, disorganized
activity that cannot effectively pump blood. Ventricular fibrillation
(fibrillation in the lower chambers of the heart) is associated with sudden
cardiac arrest.
Heart Rhythm
(ECG) Analysis ........... A system used by the FR2 to determine if the patient’s heart rhythm is
shockable — ventricular fibrillation (VF) or certain ventricular tachycardias
(VTs). See SMART Analysis.
