Fukuda Denshi HC-530, Service Manual

Page: 8 / 202

CAUTION
·
Sometimes automatic QRS detection may not be performed, even though the QRS
amplitude value is above the threshold level.
·
Automatic QRS detection may not be performed when the QRS amplitude is
extremely low and wide, or when noise is interfering.
·
Manual QRS detection is always performed on the absolute level and may cause
erroneous detection in cases where there is excessive baseline drift of the ECG
waveform. 180ms after the detection of the peak of the R-wave will be a T-Wave
Lock Out Time to prevent detecting the T-wave as QRS (double counting).
·
When turning on the AC filter or when Monitor Mode is selected, the amplitude of the
ECG waveform might become small or distorted.
·
If “LEAD OFF” condition continues when automatic lead switching is set to ON, the
ECG lead will automatically switch to another lead, and when “LEAD OFF” condition
is resolved, it will return to the original lead.
·
For using the HJ-500, proper setting on the DS-5300 bedside monitor is necessary.
Set the “HJ-500” to ON for the “MODULE CONFIG.” in the preset menu. (Refer to
the DS-5300 operation manual.)
·
When monitoring with the 3-electrode lead, proper setting on the DS-5300 bedside
monitor is necessary. Set the “HJ-500 3LEAD” to ON in the ECG configuration
menu. (Refer to the DS-5300 operation manual.)
· Manual respiration detection is always performed on the absolute level and may
cause erroneous detection in cases where there is excessive baseline drift.

·
Use electrodes and accessories specified by Fukuda Denshi. If not, the unit may
not perform its function fully and may result in skin
burns.
·
Improper cleaning of the electrodes adversely affects the calibration value.
·
Electrodes need to be calibrated. Perform calibration correctly.
·
Set the calibrated value, temperature of electrodes and monitoring time on the
monitor in advance. For the setting procedure, refer to the operation manual for the
patient monitor.
·
If electrodes are not removed from the socket within 30 minutes after the Ready LED
turns ON, electrode heating stops automatically (Ready LED turns OFF) to prevent
drying of the electrolyte. Electrodes will need to be recalibrated.
·
TcpO2 and tcpCO monitoring should be used as an auxiliary for measuring pCO in
the artery. Do not use for patients with critical blood circulation.

·
If electrodes are not removed from the socket within 30 minutes after calibration,
electrode heating stops automatically to prevent drying of the electrolyte. When
used later for measurement, electrodes need to be recalibrated.
·
The electrode may be rejected because of an incorrect preset calibration value.
Maintenance
· Do not allow alcohol or other liquids to enter the equipment and connectors.
·
Do not use organic solvents, thinner, toluene and benzene to avoid damaging the
resin cabinet.
·
Do not polish the case with abrasive or chemical cleaner.
· When sterilizing the entire room by using a spray, be cautious not to allow chemicals
to enter the device or the connector.
·
Use only the accessories specified for this equipment. Failure to use the specified
accessories may result in improper function or operation.

Dis
posing of Equipment, Accessories, or Components
When disposing of the equipment, accessories, or components, use
an industrial waste distributor. Do not dispose of as an ordinary
waste.
