5-Lead Monitoring; Simultaneous 3-Lead Printing; See-Thru Cpr Filter (Optional) - ZOLL R Series Service Manual

5-Lead Monitoring

You can perform 5-lead ECG monitoring with the appropriate ECG patient cable. The 5-lead
cable allows you to monitor the following ECG leads:
I, II, III
•
aVR, aVL, aVF
•
V1
•
Changing from 3-Lead Monitoring
To change from 3-lead to 5-lead monitoring, simply disconnect the 3-Lead ECG patient cable
(or OneStep Pacing cable ECG connector) and connect the 5-lead ECG cable. Refer to the
beginning of this section for appropriate preparations (i.e., placing electrodes, attaching
electrodes, setting the controls, etc.).
If any ECG lead becomes disconnected during monitoring, an ECG LEAD OFF message
appears on the display.
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:
To display and print 3 simultaneous leads:
1. Press the Options softkey, then press the Traces softkey.
Press 3 Leads.
2.
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
