•
Pause Limit (under Options): To adjust the number of seconds that a Pause event
must occur before the Acuity System alarms, click an arrow to specify seconds,
and then check the Pause Limit box. The default when Pause Limit is not checked
is the R-to-R interval that is greater than or equal to two times the average R-to-R.
•
Irregular limit (under Options): To adjust the minimum duration that an irregular
rhythm arrhythmia must occur before the Acuity System alarms, click an arrow to
specify seconds, and then check the Irregular Limit box.
WARNING Turning off alarming for arrhythmia types and ST Analysis disables
both audio and visual alarm indicators. Although alarming for lethal arrhythmias
cannot be turned off, patients susceptible to arrhythmias must be kept under
close physical surveillance if their alarming has been turned off for any arrhythmia
types.
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.
Always turn off Analyze
Pacers for non-paced
patients.
Single ECG enables you to
select one lead for
arrhythmia analysis. This
is useful if false alarms
occur because of a
patient’s unique beat
morphology. For details,
