Safety Instructions for ECG Monitoring
M Use the same type electrode on a patient. If skin rash or other unusual symptom occurs, remove
electrodes from patient. Do not attach electrodes on the patient with an inflammation of the skin or
scores on skin.
% Vital Signs 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).
% Vital Signs Monitor can resist against defibrillator and electro-surgical unit. Readings may be inaccurate
for a short time after or during using defibrillator or electro-surgical 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.
M Besides the improper connection with electro-surgical 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
