Monitoring during Leads Off
6-28 ECG Monitoring
Fallback for
EASI
If one of the derived EASI leads is in a technical alarm condition, a flat line is
displayed. After 10 seconds, the directly acquired EASI AI, AS, or ES lead,
depending on which is available, is displayed with the label “ECG”. Arrhythmia
relearn is performed with transition to or from EASI Fallback monitoring using
the available lead(s).
Relearning
Whenever there is a "Leads Off" condition, the arrhythmia algorithm performs a
Relearn using the available leads.
Warning Warning
Since Relearn happens automatically, if learning takes place during
ventricular rhythm, the ectopics can be incorrectly learned as the normal
QRS complex. This can result in missed detection of subsequent events of
V-Tach and V-Fib. For this reason, you should:
1. Respond promptly to any technical alarm.
2. Ensure that the arrhythmia algorithm is labeling beats correctly.
Using EASI Leads to Troubleshoot
If there is artifact in the ECG waves or a "Cannot Analyze ECG" technical
alarm condition is in effect, you can use the three EASI leads to troubleshoot at
the Information Center:
1. Click
12-Lead ECG
on the Patient Window, then on
3 EASI Leads
.
2. The three directly acquired EASI leads will be displayed so that you can
determine which electrodes are causing the problem and need to be
replaced.
