ECG MONITORING
Introduction
You can use the E Series products for either short-term
or long-term ECG monitoring.
E Series products have built-in protection circuitry to
prevent damage to their ECG monitoring circuits during
defibrillation attempts. Monitoring electrodes may
become polarized during defibrillator discharge, causing
the ECG waveform to briefly go off screen. High quality
silver/ silver chloride (Ag/AgCl) electrodes minimize this
effect, and circuitry in the instrument returns the trace to
the monitor display within a few seconds.
ECG monitoring may be accomplished through an ECG
patient cable, Multi-Function Pads or through standard
defibrillation paddles. Use of an ECG patient cable and
electrodes is required, however, to monitor during
pacing.
You can use a 3-lead or 5-lead wire configuration for
ECG monitoring. You can also view a summary of vital
sign trends if the unit is configured with other
physiological monitoring parameters, such as pulse
oximetry (SpO
2
) or end tidal carbon dioxide (EtCO
2
).
Preparations
Proper application and placement of electrodes is
essential for high quality ECG monitoring. Good contact
between the electrode and skin minimizes motion artifact
and signal interference.
Electrode Placement
Depending upon local usage, the ECG leads are marked
either RA, LA, LL, RL, and V or R, L, F, N and C. The
following table shows the markings and color codes for
the different lead sets.
* Not used for 3-lead monitoring
For information on precordial lead placement (V1 - V6),
see the
12 Lead Monitoring Operators Guide Insert .

ECG leads are a defibrillation-protected Type CF patient connection.
