15.5 Changing Size of ECG Waveform
Changing size of ECG waveform is operated on MFM-CMS.
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click ECG on the
left physiological parameter list > Choose ECG Gain > Click Update Monitor to confirm.
X0.125 to make strength of ECG signal waveform of 1mV become 1.25mm;
X0.25 to make strength of ECG signal waveform of 1mV become 2.5mm;
X0.5 to make strength of ECG signal waveform of 1mV become 5mm;
X1 to make strength of ECG signal waveform of 1mV become 10mm;
X2 to make strength of ECG signal waveform of 1mV become 20mm;
X4 to make strength of ECG signal waveform of 1mV become 40mm;
Auto let the MFM-CMS choose the optimal adjustment factor for all the ECG waves.
NOTE:
The effect of ECG waveform gain is subject to the size of the waveform area. Whichever
waveform gain is chosen, the ECG waveform has to be displayed within the waveform
area.
15.6 Changing ECG Filter Settings
Changing ECG filter settings is operated on MFM-CMS.
Enter the Parameter Setup Window (way to entering refers to 8.2 Setting Parameters) > Click ECG on the
left physiological parameter list > Choose Filter > Click Update Monitor to confirm.
– Monitor: Use this mode under normal measurement conditions.
– Surgery: The filter reduces interference to the signal. It should be used if the signal is distorted
by high frequency or low frequency interference. High frequency interference usually results in
large amplitude spikes making the ECG signal look irregular. Low frequency interference usually
leads to a wandering or rough baseline. In the operating room, the Filter reduces artifacts. Under
normal measurement conditions, selecting Surgery may suppress the QRS complexes too much
and thus interfere with the clinical evaluation of the ECG displayed on the MFM-CMS.
–Diagnosis: Use when diagnostic quality is required. The unfiltered ECG waveform is displayed
so that changes such as R-wave notching or discrete elevation or depression of the ST segments
are visible.
15.7 ECG Alarm Settings
ECG alarm settings are operated on MFM-CMS. Use can open or close the ECG alarm.
