Laerdal Twelve Lead Task Trainer - Manual (Page 7)

Overview –
The AST-12 unit is used in a teaching
environment to display 12 lead signals on
an ECG monitor. The unit is capable of
storing up to nine (9) training scenarios.
Each one can contain as many as nine (9)
steps each. The unit supports defibrillation
and pacing training and allows for
advancement to next waveform in a scenario
on a defib pulse. The unit incorporates
a two (2) line by 16 character LCD to
display current waveform information,
as well as the current scenario status.
The unit may be powered through a 12VDC 100mA AC
adapter or by two (2) ‘C’ cell batteries. When on battery
power, the unit will automatically shut off after 15
minutes of inactivity.
Operation –
This operational section assumes that unit is in default
configuration with no scenarios programmed into the unit.
When unit is powered “On,” it will begin an initialization
routine. During this time, the remote control unit will
display the model name on top line and version number
on bottom line.
After a brief delay, unit will initialize to waveform mode
‘WFM’ with pacing disabled ‘N’ and set to waveform #21
‘Normal Sinus’. At this point, the unit will output 12 lead
waveform data.
Using the remote control unit as a guide, and starting at
the top left, the displayed items are:
• Current mode (MOD)
• Current scenario # (SCEN)
• Current scenario step # (STEP)
• Scenario defib step advance (DFIB)
• Pacing mode (PACE)
• Scenario step timer (TMR)
On the bottom of remote control are the waveform
number (#) (WAVEFORM) and waveform name.
