Monitoring ECG
This chapter describes how to use the Propaq M unit to monitor ECG.
You can use a 3-lead, 5-lead, or 12-lead wire configuration for ECG monitoring (see Chapter
13, Monitoring 12-Lead ECG, for information on 12-lead monitoring).
Warning! • Excessive body hair or wet, sweaty skin may interfere with electrode adhesion.
Remove the hair and/or moisture from the area where the electrode is to be attached.
• Use only electrodes that are well within the expiration date indicated on the package.
• Remove ECG electrodes from their sealed package immediately prior to use. Using
previously opened or out-of- date electrodes may degrade the ECG signal quality.
• Monitoring electrodes may become polarized during defibrillator discharge, causing
the ECG waveform to briefly go off screen. ZOLL Medical Corporation recommends
the use of high quality silver/silver chloride (Ag/AgCl) electrodes to minimize this
effect; the circuitry in the instrument returns the trace to the monitor display within
a few seconds.
• To assure protection against the effects of defibrillator discharge, use only
ZOLL-approved accessories.
• To avoid a shock hazard and interference from nearby electrical equipment, keep
electrodes and patient cables away from grounded metal and other electrical
equipment.
