ZOLL E Series Monitor Defibrillator Rev C - Manual (Page 4)

Non-Interpretive 12-Lead ECG Monitoring
2 9650-1215-01 Rev. C
WARNINGS
• Before use, carefully read the E Series Operator's Guide and these operating instructions.
• Always ensure that the patient is kept motionless during 12-lead ECG signal acquisition. Use of the device to
acquire ECG signals from moving or shaking patients may produce erroneous 12-lead data.
• 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.
• 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.
• Wait 15 seconds after defibrillator discharge before attempting a 12-lead acquisition. Electrode polarization
subsequent to defibrillator discharge may result in excessive noise on the 12-lead ECG printout.
• When not in use, cover the patient cable's V-lead connector with the supplied plastic cap. Failure to do so may
result in a shock hazard during defibrillation attempts.
• To assure protection against the effects of defibrillator discharge, use only 12-lead cables supplied by ZOLL
Medical Corporation.
• To avoid a shock hazard and interference from nearby electrical equipment, keep electrodes and patient cables
away from grounded metal and other electrical equipment.
• Do NOT sterilize the E Series unit or any of its 12-lead accessories.
• Check the operation and integrity of the E Series and 12-lead cable regularly by performing the Daily Operational
Verification Test.
• The frequency response of the monitor screen is intended only for basic ECG rhythm identification; it does not
provide the resolution required for diagnostic and ST segment interpretation. Use the stripchart recorder for this
purpose.
• Implanted pacemakers may cause the heart rate meter to count the pacemaker rate during incidents of cardiac
arrest or other arrhythmias. Carefully observe pacemaker patients. Check the patient's pulse; do not rely solely on
heart rate meters. Dedicated pacemaker detection circuitry may not detect all implanted pacemaker spikes.
Patient history and physical exam are important in determining the presence of an implanted pacemaker.
