CPR SIMULATOR, R SERIES
SeeThru CPR Simulator
Product Description
USER NEEDS AND INTENDED USES
The SeeThru CPR Simulator is designed to be a training tool for use with ZOLL AEDs, as well as 3lead ECG monitors/defibrillators/external pacers that have hands-free cables. It provides a safe way
to learn and to demonstrate the operation of emergency cardiac care equipment outside of an
emergency situation.
Users can discharge a defibrillator or pacer directly into the simulator. When training for defibrillation,
the convert feature allows the operator to select - before a defib discharge - another rhythm to be
simulated automatically after the defib discharge.
When the operator initiates pacing, the simulator generates paced captured beats.
Fourteen waveforms are available to help users identify fibrillations, tachycardias, and bradycardias.
The battery saver feature powers-off the simulator automatically when it is not in use.
PHYSICAL DESCRIPTION
Keys
The key panel is constructed from momentary tactile push buttons mounted to a printed circuit board
and covered with an embossed overlay.
Indicators
Each rhythm has an associated green LED that illuminates when its key is pressed. (An illuminated
key is also the indication that the simulator is powered-on.)
Detection of a defib discharge is indicated by briefly illuminatiing a green LED labeled DEFIB
DSCHG.
Detection of a pacer pulse is indicated by flashing a green LED labeled PACER PULSE.
A low battery state is indicated by steadily illuminating a red LED labeled LOW BATT.
Connectors
A PADS connector is located on an end panel that faces away from the user during normal use.
Three ECG snaps are mounted on the right vertical side of the enclosure for connecting RA, LA,
and LL ECG cable leads.
Battery Compartment
The battery compartment is externally accessible. No tools are required to gain access to the
batteries.
Size and Weight
Outside dimensions are: 6.25” (L) x 3.7” (W) x 1.8” (H). It weighs 1.0 +/- .1 pounds.
CONTROLS
Pressing the ON/OFF key when the simulator is off causes it to power-on. At power-on, NSR is
automatically selected, and the NSR LED glows steadily. Pressing the ON/OFF key when the device
is on causes it to power-off.
Rhythms
The SeeThru CPR Simulator has 14 waveforms to choose from.

The user selects a rhythm by pressing the rhythm’s key. The key’s LED will illuminate when the
selection has been made. If the user presses the key of the displayed rhythm, there will be no
observable effect - the LED will not flicker and the rhythm will not “start over”.
Convert
The convert feature provides a convenient way for the operator to select - before a defib discharge another rhythm to be generated automatically after a defib discharge. The convert feature can be
enabled two seconds after the simulator is powered-on.
When the convert key is pressed, the LED of the running rhythm will pulse brighter to that the
simulator is in the convert mode.
Next, when the key of the waiting rhythm is pressed (the rhythm to be displayed after the defib
discharge), its LED will flash on and off. The LED of the running rhythm will revert back to a steady
glow.
When a defib discharge is delivered from a defib set to 50J or more, the LED of the running rhythm
goes out. The LED of the waiting rhythm now glows steadily because it is the new running rhythm.
Pacer pulses that cause simulation of paced captured beats can also be used to convert from one
rhythm to another. This may be helpful when demonstrating overdrive pacing.
If the convert key has been pressed, but the user decides to cancel the convert operation, the user
can revert back to the normal running mode by either pressing the convert key again, or by pressing
the key of the running rhythm.
If the convert key has been pressed, and the waiting rhythm has been selected, but the user decides
to select a different waiting rhythm, the user can make the new selection without canceling the
convert operation.
If 1.5 minutes has elapsed since pressing a key in the convert sequence, and there has been no
detection of a defib discharge (50J or greater) or a pacer pulse (above the capture threshold), then
the convert mode will cancel automatically and the simulator will revert to the normal running mode.
ECG WAVEFORM GENERATION
ECG signals present at the RA, LA, and LL external ECG snaps are separate, independent signals,
and appear to have been derived from the same cardiac voltage vector. The signal available through
the PADS connector resembles lead II.
DEFIB DISCHARGE DETECTION
The simulator indicates delivery of a defib discharge when the discharge comes from a defib set to
50J or more. Instead of flashing briefly - for only the duration of the defib discharge - the DEFIB
DSCHG indicator will glow steadily for 2.5 seconds following the detection of the defib discharge,
giving the operator ample time to see the indicator before it goes out. Pacer pulses do not cause the
DEFIB DSCHG indicator to illuminate.
The defib load will tolerate, without damage, continual delivery of 360J defib discharges that may be
encountered when rapid defibrillation is being demonstrated. This assumes a charge time of eight
seconds, a discharge, and then three seconds of patient assessment before charging the defibrillator
again.
PACER PULSE DETECTION & DISPLAY OF CAPTURED BEATS
When pacer pulse current is set to 45mA to 50mA, and above, the SeeThru CPR Simulator indicates
detection of a pacer pulse by generating a paced captured beat and by flashing the PACER PULSE
indicator.
When NSR, Asystole, or the Bradycardias are being paced by a PD1400, and captured beats are
displayed, decreasing the pacer rate so that it is equal to or less than the rate of the running rhythm,
+/- 4 ppm, will cause the underlying rhythm to reappear after one or two pacer pulses.
When the Tachyarrhythmias are being paced, and captured beats are displayed, decreasing the
pacer rate to 80 PPM, +/- 4 ppm, will cause the underlying rhythm to reappear after one or two pacer
pulses.
If pacing is stopped, the simulator will revert to the underlying rhythm within 2 seconds.
The PACER PULSE indicator flashes briefly for each pacer pulse detected. Defib discharges will not
cause the PACER PULSE indicator to flash.
Pacing and VF
Pacing is not considered to be an acceptable treatment for VF. Therefore, the simulator will not
generate paced captured beats when VF is the running rhythm.
POWER
The simulator is powered from one 9 volt alkaline battery. It will operate continuously for
approximately 15 hours until the LOW BATT indicator illuminates.
Battery Saver Feature
To help prolong battery life, the simulator automatically powers-off one half hour after (1) selecting a
waveform , or (2) detecting a defib discharge, or (3) detecting a pacer pulse. This is normal
operation.
However, there may be times when the operator wants the simulator to remain on until the OFF key
is pressed (for example, at a trade show). The battery saver feature can be disabled during a two
second period following power-on. This is accomplished by first powering-off the simulator, then
pressing the convert key and the ON key simultaneously. The NSR indicator will flash rapidly for
two seconds to let the user know that the battery saver feature has been disabled. When the
simulator is powered-off, it will return to normal battery saver operation.
Low Battery Detection
When the battery voltage drops to approximately 5.8 volts, the LOW BATT LED will glow steadily
indicating a low battery condition. The operator should replace the battery as soon as possible after
the low battery indicator illuminates.
