Changing from 5-Lead ECG Monitoring
To change from 5-lead monitoring to 3-lead monitoring, you must power off the unit for at least
10 seconds, remove the 5-lead cable, connect the 3-lead cable, then power on the unit again. If
you fail to shut the unit off for at least 10 seconds, the unit displays the ECG LEAD OFF
message after you disconnect the 5-lead wire cable, even if leads from a 3 lead ECG cable are
properly attached to the patient.
Simultaneous 3-Lead Printing
The R Series unit can display and print three simultaneous ECG leads when using a 5 lead
cable and an ECG lead is selected as the signal source (not PADS or PADDLES).
Note: This feature does not work with a 3 lead cable.
To display and print 3 simultaneous leads:
1. Press the Options softkey, then press the Traces softkey.
2. Press 3 Leads.
Leads belong to two groups: limb leads (I, II and III) and augmented leads (aVR, aVL, and
aVF). The selected lead is always displayed and printed in the Trace 1 uppermost position. The
other two leads are displayed in the Trace 2 and 3 positions. For example, if aVL is the selected
Trace 1 lead, the Trace 2 and 3 positions display aVR, and aVF respectively.
3 ECG leads will also be printed (when an ECG lead is selected) if the “Print 3 Leads When
Leads are Sel.” configuration option is set to YES. Refer to the R Series Configuration Guide
for instructions.
See-Thru CPR Filter (Optional)
When OneStep CPR electrodes or OneStep Complete electrodes are in use, the R Series unit
allows simultaneous display and printing of the selected ECG lead and the same ECG lead with
CPR filtering applied. The CPR filter uses signals from the electrode’s CPR sensor to help
reduce artifact in the ECG signal caused by mechanical compressions of the chest, thereby
providing a clearer view of the ECG during periods of CPR. For more detailed information on
this feature, see Chapter 7, "See-Thru CPR (Optional)".
To apply the See-Thru CPR Filter to the selected ECG lead and display it:
1. Press the Options softkey, then press the Traces softkey.
2. Press the Trace 2 or Trace 3 softkey.
3. Press Filt ECG.
If Display Filtered ECG in Trace1 is configured, the unit displays the filtered ECG in Trace1.
You can then switch between filtered and unfiltered ECG using the Enable/Disable Filt ECG
softkey. With the unfiltered ECG displayed in Trace1, the user of the R Series unit can also
enable the display of the filtered ECG in Trace2 or Trace3.
Adding Traces to Be Displayed
The screen can display up to three traces simultaneously. The trace for the selected ECG lead
always appears in the Trace 1 uppermost position.
