134 Chapter 8 Discontinue Acuity System monitoring
WARNING If your system includes arrhythmia analysis, and if you connect,
change or move an electrode, ensure that a RELEARN alert occurs at the patient
monitor and the virtual monitor.
Moving or changing an electrode can change the beat morphology. If the system
does not learn the new morphology, it might not alarm or it might cause false
alarms. The relearn process establishes the new morphology as the normal ECG
rhythm for arrhythmia and ST-segment analyses.
• If a RELEARN alert occurs after changing or moving an electrode, carefully
evaluate the new ECG rhythm and the current ST segment for all active leads
to make sure that the Acuity System has learned an appropriate rhythm. For
evaluation instructions, see
• If a RELEARN alert does not occur after changing or moving an electrode,
initiate a relearn event. For instructions, see
ECG rhythm for arrhythmia and ST-segment analyses"
WARNING Minimize patient movement during a RELEARN, as movement
creates noise during the reading. If the system learns an abnormal rhythm or
learns a rhythm during noise, it designates the learned rhythm as normal.
Thereafter, rhythms of this type might not trigger an alarm. Ensure that the
patient remains still for 5 minutes after the RELEARN before allowing them to
move.
