• LEAD FAULT MESSAGE - The lead fault message box displays “ECG Lead Fault” and is
positioned over the area where the ECG waveform normally resides.
•
PACER ENHANCEMENT
- Factory default is “Pacer enh OFF” (pacer enhancement off).
The OFF setting allows any pacer to appear as it normally would on the ECG waveform.
When pacer enhancement is turned on via patient menu selection, detected pacers are
enhanced and appear as full scale, narrow square waves.
WARNING: Thoracic respiration measurement may interfere with some
pacemakers. Refer to the pacemaker’s manual.
•
INTERFERENCE MESSAGE
- When large 60 Hz noise component is present on the ECG
waveform and the notch filter is enabled, the “Interference” message is displayed. The
“Artifact” message will also be displayed in the Parameter Display area. Check the
patient electrode connectors and the cable for proper connection. This message may be
the result of using inappropriate 3-Lead cables.
•
ESU INTERFERENCE MESSAGE
- When a large high frequency noise component is
present on the ECG waveform, the message “ESU Interference” is displayed. If both high
frequency and 60 Hz noise are present, the “ESU Interference” message and the Artifact
message are displayed.
1.6.3.3 Multi-function Display Area
FIGURE 1-62 Multi-Function Display Area
Displayed within the Multi-function Area of the screen are the:
A. Waveforms
B. Trend Lists
A. Waveforms
The waveform display is the normal display in the multi-function area. The waveforms occupy
the entire multi-function area.This area is divided horizontally in two. These two areas are
used for waveforms 2 and 3.
The options for each waveform are listed in Table 1-4, page 1-23.
The scale information for invasive pressures consists of a 0 at the bottom of each window to
represent zero pressure level and the scale range value at the top of the window.
The waveform provides four seconds of data when the selected speed is 25mm/sec.
