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.
• To avoid electrosurgery burns at monitoring sites, ensure proper connection of the
electrosurgery return circuit so that the return paths cannot be made through
monitoring electrodes or probes.
• Check the operation and integrity of the X Series unit and ECG cable regularly by
performing the Daily Operational Verification Test.
• 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.
