11.4 ECG Screen Hot Keys
Figure 11-5 The Hot Key For ECG
①
Leads of channel 1:
1)
The selectable leads are I, II, III, aVR, aVL,aVF, V.
2)
When the ECG is 5-lead, the selectable leads are: I, II, III, aVR, aVL, aVF; V. when ECG is 3-lead, the selectable
leads are: I,II,III.
3)
Leads on the ECG wave must not have the same name. Otherwise, the system will automatically change the ECG
waveform name that has the same name as the waveform being currently adjusted to another name.
②
Waveform gain of channel 1: used to adjust the size of ECG waveforms
Select gain value for each channel from ×0.25,×0.5,×1,×2,×4. A 1mv scale displays on each ECG channel's one side.
The height of 1mV bar is directly proportional to the waveform amplitude.
Note
When the input signals are too large, the peak of the waveform may be not able to be displayed. In this case
the user may manually change the setup method of ECG waveform according to the actual waveform so as
to avoid the occurrence of the unfavorable phenomena.
③
Filter method: used for displaying clearer and more detailed waveform
There are three filter modes for selection. DIAGNOSTI, MONITOR and SURGERY modes may reduce perturbance
and interference from Electrosurgery equipment. The filter method is the item applicable for both channels, which is
always displayed at the waveform place of the channel 1 ECG waveform.
Note
Only in Diagnosis mode, the system can provide non-processed real signals. In Monitor or Surgery mode,
ECG waveforms may have distortion of different extent. In either of the latter two modes, the system can
only show the basic ECG and the results of ST analysis may also be greatly affected. In Surgery mode,
results of ARR analysis may be somewhat affected. Therefore, it is suggested that in the environment
having relative small interference, you’d better monitor a patient in Diagnosis mode.
