4. ECG Monitoring

CAUTION

 The threshold level for HR detection of this equipment and the receiving

monitor changes with ECG waveform size. Set a proper waveform size

for monitoring.

 There are some cases when pacemaker pulse cannot be detected

depending on the pacemaker type, pulse voltage, pulse width,

electrode lead type (unipolar, bipolar), electrode placement, or lead

method which causes the pacemaker pulse amplitude to decrease and

disables pacemaker pulse detection.

 If signals similar to a pacemaker pulse are present, such as electric

blanket noise or excessive AC frequency noise, these may be

erroneously detected and displayed as a pacemaker pulse. In this

case, check the condition of the electrodes and ECG lead cable to

resolve the cause or turn off the pacemaker detection setting on the

receiving monitor.

 Time constant of this equipment is shorter than Fukuda Denshi

monitors (direct ECG connection). Therefore, there is a difference in the

ST measurement value between them. Pay attention to the difference

when monitoring a patient from a transmitter or a monitor.

 When an electrode is attached on the same location for a long time,

some patients may develop skin irritation. Check the patient’s skin

condition periodically and change the electrode position as required.

 The indication for continuous use of an electrode is about one day.

 Replace the electrode if the skin contact gets loosen due to perspiring,

etc.

 Make sure to use new disposable electrodes. Otherwise, the waveform

quality may become poor and it may fail to perform correct monitoring

 When “Check Electrode” message is displayed on the screen of the

receiving monitor or the display of this equipment, check the condition

of the electrodes and ECG lead cable to resolve the cause.

 When removing electrodes from the patient, remove them carefully and

slowly. Do not apply excessive force to remove them. Otherwise, it may

damage the skin.

 A correct measurement may not be performed depending on the

attached position of the electrodes. Attach the electrodes on the patient

referring to “■Connecting the ECG Lead Cable and Electrodes” and

make sure that the correct waveform is measured on the display.
