Manual of OMNI Express Patient Monitor
- 24
037.007.0001 Rev.2
Select from 12.5 mm/s, 25 mm/s and 50 mm/s. The factory setting is 25
mm/s.
SWEEP COLOR
Select from White, Gray, Red, Yellow, Green, Cyan, Blue, and Magenta. The default
setting is Green.
PACEMAKER DETECTION
It is important to set the paced status correctly when you start monitoring ECG. When the
Pacemaker Detection is set to ON, the pace pulse markers

are shown on the ECG
waveforms when the patient has a paced signal.
ECG TEST
Used by engineers only.
ECG VERIFY
Used by engineers only.
ST-SEGMENT ANALYSIS
ST-segment analysis calculates ST-segment elevations and depressions for individual
leads and then displays them numerically in the ECG Parameter area. A positive value
indicates ST-segment elevation; a negative value indicates ST segment depression. This
feature is not intended for neonatal patients.
As shown in the figure below, the ST measured for each beat complex is the vertical
difference between two measurement points with the R-wave peak as the baseline for the
measurement.
ST ALARM SWITCH
The default value is
OFF
. The alarm is triggered when the ST measurement value
exceeds the alarm limits. If the ST Alarm is
ON
, the ST value blinks, the alarm sounds the
[WARNING]
1. For paced patients, you must set Pacemaker Detection to ON. If it is incorrectly
set to OFF, the patient monitor could mistake a pace pulse for a QRS and fail to
alarm when the ECG signal is too weak. DO NOT rely entirely on alarms when
monitoring patients with pacemakers. Always keep these patients under close
surveillance.
2. For non-paced patients, you must set Pacemaker Detection to OFF. If it is
incorrectly set to ON, the patient monitor may be unable to detect premature
ventricular beats (including PVCs) and perform ST segment analysis.
