ECG/RESP Monitoring
11-3
„ DIAGNOSTIC: The monitor displays the ECG waveforms without filter;
„
MONITOR: It effectively filters the artifacts that might cause false alarms;
„ SURGERY: This filter is used to reduce the artifacts and interference from
electrosurgery equipment.
The selected filter is applied to both channels, but the filter label is merely displayed
above the first ECG waveform.
WARNING
z
Only in the DIAGNOSTIC mode will the monitor provide non-processed
real signal waveforms. In the MONITOR or SURGERY mode, the ECG
waveforms may have slight distortions and the result of the ST segment
analysis may be affected greatly. In the SURGERY mode, the ARR
analysis result may be affected to some extent. Hence, the DIAGNOSTIC
mode is recommended when monitoring a patient in an environment
with slight interference.
4. ECG lead of channel 2: You can select the lead of channel 2 in the same
method used to select the channel-1 lead.
5. Gain of the channel-2 waveform: You can adjust the gain of the channel-2 ECG
waveform in the same method used for channel 1.
NOTE
z
If the amplitude of an ECG waveform is too large, the peak of the
waveform might not be displayed. In this case, you should change the
waveform gain properly.
z
At present, the central monitoring system of us is unable to display an
ECG waveform of the gain ×0.125. If your monitor is connected with this
system, the ECG waveform displayed by the central monitoring system
will be changed from ×0.125 to ×0.25.
z
The selected leads of channel 1 and channel 2 should not be identical.
Otherwise, the system will change one of them automatically. In the
MULTI-LEADS DISPLAY mode or the HALF-SCN MUTLI-LEADS display
mode, the leads of both channels cannot be set.
z
A pacemaker signal, when detected, is marked by "
︱
" above the ECG
waveform.
