Safety Instructions for ECG Monitoring
Deluxe-100, EBM VS-100 Multi-parameter Patient Monitor can only be equipped with ECG leads
provided by our company; using ECG leads supplied by other companies may cause improper
performance or poor protection while using defibrillator.
Electric parts of electrodes, leads and cable are forbidden to contact any other conductive parts
(including ground).
Deluxe-100, EBM VS-100 Multi-parameter Patient Monitor can resist against defibrillator and
electrosurgical unit. Readings may be inaccurate for a short time after or during using defibrillator or
electrosurgical unit.
Transient caused by cable circuitry blocks while monitoring may be similar to the real heartbeat
waveform, as a result resistance heart rate alarm rings. If you put the electrodes and cable in proper
places according to this
manual’s instructions and the instructions for using electrode, the chance of
this transient occurring will be decreased.
To the patient with pacemaker, due to that this device has been designed to provide resistance to
pacemaker signal interference, generally the pacemaker pulse is not counted in heart rate
measurement and calculation, but when the cycle time of pacemaker pulse is over 2ms, it may be
counted. In order to reduce this possibility, observe the ECG waveforms on the screen carefully and
do NOT rely entirely on the heart rate display and alarm system of this monitor when monitoring this
kind of patients.
Besides the improper connection with electrosurgical unit may cause burns, the monitor may be
damaged or arouse deviations of measurement. You can take some steps to avoid this situation,
such as do NOT use small ECG electrodes, choosing the position which is far away from the
estimated Hertzian waves route, using larger electrosurgical return electrodes and connecting with
the patient properly.
ECG leads may be damaged while using defibrillator. If the leads are used again, please do the
functional check first.
3.3.2 Blood Pressure Cuff Connection
1. Connect the cable to the right-panel connector marked with the NIBP icon.
2. Select a cuff of appropriate size according to the age of the subject. Its width should be 2/3 of the length
of The upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb
concerned. See the table below for the dimensions:
Note: The size of the cuff selected should suit the subjects while measuring.
