Start A Merlin™ Psa Session - Abbott Merlin PSA EX3100 Help Manual

Connect the (+) and (-) patient-cable to the appropriate connection on the lead. Refer
-
to the appropriate lead manual for information on the lead configuration.
The clips on the Model EX3150 patient cable can be positioned side by side, with the lead
electrodes visible through the clip.
Figure 8. Two views of the Model EX3150 clips connected to an DF4 lead: 1) Single clip
connected to the lead connector electrode, approached from the front; 2) Two clips connected
to the lead connector electrode rings, approached from the side. Use the window on the top of
the clip to visualize the connection to the electrode.
NOTE: Use care when connecting the sterile patient cable to the lead. Avoid contamination
of or damage to the sterile connectors or leads. See Cleaning, Disinfecting, and Sterilization
Methods (page 47).
CAUTION:
Do not allow conductive parts of leads or connectors to come into contact

with other conductive parts, including Earth ground.
Ensure that the leads are connected to the appropriate channel. Incorrect

connections could result in inappropriate or harmful stimulation as well as
inaccurate intrinsic signal amplitude and slew rate measurements.
In the event of power loss or communication failure, the Merlin PSA switches

to battery power to continue operation. If this occurs, the Merlin PSA
operates in Safe Pacing mode for as long as the battery life permits or until
power is restored to the Merlin PCS or Merlin 2 PCS and a PSA session is
started. To ensure that the battery life is sufficient, the Merlin PCS or Merlin
2 PCS measures the Merlin PSA battery voltage when it is turned on. If the
batteries cannot sustain PSA operation for at least 30 minutes, you will see
an alert indicating that the batteries are near depletion and should be
changed. See Safe Pacing (page 33) and Battery Information (page 45).
Leaving the atrial connector disconnected when the Merlin PSA is in DDD or

VDD modes may result in the unit sensing external noise and increasing the
ventricular pacing rate to the Max Track Rate.
Start a Merlin™ PSA Session
You can start a PSA session from the Start-Up Screen or during a device programmer session.
The Merlin™ PSA imports patient and device data from the ongoing device session into the PSA
session.
To begin a PSA session:
1. From the Start-Up Screen or during a device programming session, select Tools > PSA.
