The threshold level for arrhythmia detection changes with ECG
waveform size. Set a proper waveform size for monitoring.
When the waveform size is
?
1/4,
?
1/2, or
?
1, the detection threshold is
250 µV.
When the waveform size is
?
2 or
?
4, the detection threshold is 150 µV.
?
Automatic size/position of the ECG is effective only at the time the
AUTO key is pressed. This does not continually adjust size and
position.
?
There are some cases when 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 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.
?
When automatic QRS and pacemaker pulse overlap (ex. fusion beat,
etc.), QRS detection cannot be performed properly. In this case, the
heart rate is degraded.
?
When continuously detecting AC noise artifact as pacemaker pulses,
QRS detection stops and heart rate is extremely degraded. Also
arrhythmia cannot be detected.
?
Respiration Monitoring
?
When the following relay cables are used, respiration can not be
measured.
・
Relay Cable CI
‐
700E_3 (Electrosurgery-proof, 3-electrode)
・
Relay Cable CI
‐
700E_4 (Electrosurgery-proof, 4-electrode)
・
Relay Cable CI
‐
700E_5 (Electrosurgery-proof, 5-electrode)
?
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.
?
When the following lead cables are used, respiration cannot be
measured.
・
Lead Cable #3380.0648.16 (Electrosurgery-proof, 3-electrode)
・
Lead Cable #3380.0661.16 (Electrosurgery-proof, 5-electrode)

Monitoring
?
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.
?
If irritation such as skin reddening or skin fit appears with the sensor use,
change the attachment site or stop using the sensor.
?
When fixing the sensor with a tape, do not wind the tape too tigh
ｔ
. At
the same time, check the blood flow constantly so that congestion is not
generated at the peripheral.
?
Even a short duration of attachment may inhibit the blood flow and
generate compression necrosis and burn injury
?
Change the sensor attachment site constantly (every 4 hours). As the
temperature of sensor attachment site normally rises 2
〜
3
?
C,
compression necrosis and burn injury may generate.
?
As skin for neonate / low birth weight infant is immature, change the
sensor attachment site more frequently depending on the condition.
?
Direct sunlight to the sensor area can cause a measurement error.
Place a black or dark cloth over the sensor.
?
When not performing the measurement, unplug the relay cable and
sensor from the SpO
2
connector. Otherwise, the measurement data
may be erroneously displayed by the ambient light.
?
NIBP Monitoring
?
If the air hose is twisted, or weighed down, the cuff air can not be
exhausted. Properly arrange the cuff and air hose.
