ECG/RESP Monitoring
11-2
11.1 Overview
11.1.1 ECG Waveform
In the standard screen, one or two ECG waveform(s) is (are) displayed at the top of
the display when LEAD TYPE is set to 3 LEADS or 5LEADS respectively in the
ECG SETUP menu.
Figure 11-1 ECG Waveforms
As shown above, when 5 LEADS is selected, five labels are located above the ECG
waveforms:
1. ECG lead of channel 1
You can select the lead of channel 1 from the label options.
„ When you use a 3-lead set, the monitor gives three lead options: I, II and III;
„ When you use a 5-lead set, the monitor gives seven lead options: II, III, aVR,
aVL, aVF, V and I.
2. Gain of the channel-1 waveform
You may use this label to adjust the amplitude of the channel-1 ECG waveform. The
gain options include ×0.125, ×0.25, ×0.5, ×1, ×2 and AUTO. When AUTO is
selected, the monitor adjusts the gain automatically. Besides, a 1mV scale is
displayed at the right side of each ECG waveform. The height of the 1mV bar is
directly proportional to the ECG waveform amplitude.
3. Filter Method
The filtering enables clearer and more detailed waveforms. There are three filter
methods for selection.
