ECG
WARNING
— ELECTRODES — Whenever patient defibrillation is
a possibility, use non-polarizing (silver/silver chloride
construction) electrodes for ECG monitoring. Polarizing
electrodes (stainless steel or silver constructed) may cause
the electrodes to retain a residual charge after defibrillation. A
residual charge will block acquisition of the ECG signal.
WARNING
— DEFIBRILLATOR PRECAUTIONS — Patient signal inputs
labeled with the CF and BF symbols with paddles are
protected against damage resulting from defibrillation
voltages. To ensure proper defibrillator protection, use only
the recommended cables and leadwires.
WARNING
— HEART RATE ALARM INTERFERENCE — Poor cable positioning
or improper electrode preparation may cause line isolation
monitor transients to resemble actual cardiac waveforms and
thus inhibit heart rate alarms. To minimize this problem, follow
proper electrode placement and cable positioning guidelines
provided with this product.
ECG cautions
CAUTION
The patient's skin may become irritated after prolonged
contact with electrode gel or adhesive.
CAUTION
To assure accurate 12 lead analysis when using a 10-leadwire
patient cable, you must verify that the correct leadwire block is
plugged into the appropriate side of the cable. The V2 through
V6 leadwire block is color-coded brown (AHA) or white (IEC).
ECG measurement limitations
●
E-modules used for this measurement are not suitable for use with neonatal
patients.
●
The monitor will display a Leads off message in an input overload condition, or
upon disconnection of electrode leadwires.
ECG points to note
●
Pre-gelled ECG electrodes are recommended. Check the expiration date.
●
Make sure the electrode gel is moist.
●
Make sure the electrodes have good skin contact.
●
Replace all electrodes at least every 24 to 48 hours.
●
Use the Multi-Link electrosurgical unit (ESU) ECG patient cable when using the
monitor in the presence of an electrosurgical unit. This cable, with a built-in ESU
filter, helps reduce electrosurgical noise detected on the ECG signal.
●
E-modules: Whenever a cable, electrode or V-lead is changed, the monitor
automatically relearns.
●
Depending on the ECG module used, not all ECG measurements and settings are
available to view or change.
●
Select the Deactivate ECG Leads Off option to remove a Leads off message from
the display when a cable is off.
