z HS-8000 System
y Use only the accessories specified for this unit. Otherwise, proper function
cannot be executed.
y For quality improvement, specifications are subject to change without prior
notice.
y This equipment is intended to be used for only one patient.
z
ECG Monitoring
y Use only the specified relay cables, lead cables, and electrodes.
y The conductive parts of electrodes and associated connectors for applied parts,
including the neutral electrode, should not contact other conductive parts
including earth.
y The indication for continuous use of the electrode is about one day.
y Replace the electrode if the skin contact gets loosen due to perspiration.
y When an electrode is attached to the same location for a long period, some
patients may develop skin irritation. Check the patient
’
s skin condition
periodically and change the electrode site as required.
y
Even the ECG waveform has a minimum threshold level, QRS Automatic
Detection may not be automatically conducted.
y The following EGC may not be automatically detected.
・
The QRS amplitude is low and the QRS width is extremely wide.
・ The interference of artifacts such as EMG or body motion is large.
・
Loud noise is generated by electrosurgical instruments.
y There are some cases when the pacemaker pulse can not be detected
depending on the pacemaker type, pulse voltage, pulse width, electrode lead
type (unipolar, bipolar), or electrode placement which causes the pacemaker
pulse amplitude to decrease and disables the pacemaker pulse detection.
y 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.
y When the spontaneous QRS and pacemaker pulse overlaps (as in a fusion
beat), QRS detection will be suspended and the heart rate will be reduced.
y
If a pacemaker pulse is continuously detected due to AC frequency interference,
QRS detection will be suspended and the heart rate will be reduced.
z
Arrhythmia Analysis
y For proper arrhythmia detection and ECG monitoring, verify proper electrode
placement, lead selection, and ECG waveform size. If necessary, turn ON the
AC filter. Improper electrode placement, lead selection, and ECG waveform size
can cause errors in detection.
z Respiration Monitoring
y When a defibrillator is used during respiration monitoring, a large offset voltage
will be placed on the ECG electrodes, which may cause interruption of
monitoring for a few seconds.
z SpO
2
Monitoring
y If the nail is rough, dirty, or manicured, accurate measurement will not be
possible. Change the finger or clean the nail before attaching the probe and
sensor.
y
If irritation such as skin reddening appears with the sensor use, change the
attachment site or stop using the sensor.
y When attaching the sensor with tape, do not wrap the tape too tight. At the
same time, check the blood flow constantly so that congestion is not generated
at the peripheral.
y Even a short duration of attachment may inhibit the blood flow and generate
compression necrosis and burn injury. SpO
2
may not be measured correctly
because of inhibition of blood flow.
y Change the sensor attachment site constantly (every 4 hours). As the
temperature of sensor attachment site normally rises 2 to 3
°
C, compression
necrosis and burn injury may generate.
y As the skin of neonate/low birth weight infant is immature, change the sensor
attachment site more frequently depending on the condition.
y Direct sunlight to the sensor area can cause measurements error. Place a black
or dark cloth over the sensor.
y When not measuring, unplug the relay cable and sensor from the SpO
2
connector. Otherwise, the outside light may affect to falsely display
measurements.
