Welch Allyn  Acuity Central Monitoring System

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 

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.
