8-12 Dash 2000 Patient Monitor Revision C
2005873-001
Smart-Lead Fail
Leads Fail Patient
Condition
NOTE: The smart-lead fail feature works only when using a 5-leadwire
electrode configuration.
The smart-lead fail feature is continually checking the integrity of the electrodes
to allow uninterrupted monitoring. Should the quality of an electrode signal
degrade to an inadequate level, a lead fail message will be displayed. If the
lead fail affects the ECG waveform monitored in the top trace position on the
screen, monitoring will
automatically switch to another lead. Refer to the
chart below.
Message IEC Label New lead monitored
RA FAIL R Lead III
LL FAIL F Lead I
LA FAIL L Lead II
V FAIL C Lead II
LEADS FAIL No waveform displayed—right leg
fail or multiple leads fail
Individual lead fail messages will not be displayed when using single-lead
analysis, but lead switching will occur.
There is a system alarm to alert you when more than one lead fails. In OR
mode, the monitor defaults this ”leads fail patient” condition as a system
ADVISORY alarm. You can, however, set it as a CRISIS alarm in Monitor
Defaults.
In Adult-ICU and Neonatal-ICU modes this alarm defaults to a system
WARNING alarm but can also be set to a CRISIS alarm. Refer to Setup Default
Display section in Chapter 5, Monitor Setup.
