y When arrhythmia is present, HR measurement accuracy may be
degraded.
y Select the appropriate lead for ECG1, 2 to be used for arrhythmia
detection, telemeter, central monitor transmission, and recording.
y The selected lead for ECG l, 2 will be used for recall waveform and
recording waveform as well as for arrhythmia analysis.
y While the “LEAD OFF” message is displayed, HR alarm and arrhythmia
alarm will not function. Leaving this condition unresolved may result in
missing a sudden change of the patient. Promptly check the electrodes
when this message is displayed.
y The arrhythmia detection leads, monitoring leads on the central monitor,
recording leads are fixed as ECG1 and ECG2 leads. Especially for
arrhythmia detection, set the most appropriate leads with high QRS for
ECG1 and ECG2.
y 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.
y The ESIS mode can largely reduce the artifact such as electrosurgery
noise and EMG, but it may also reduce the QRS amplitude. The ESIS
mode should be selected only during electrosurgery.
y There are some cases when pacemaker pulse cannot 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.
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 spontaneous QRS and pacemaker pulse overlap (ex. fusion beat,
etc.), QRS detection cannot be performed properly. In this case, the
heart rate is degraded.
y When continuously detecting AC noise artifact as pacemaker pulses,
QRS detection stops and heart rate is extremely degraded. Also
arrhythmia cannot be detected.
z Respiration Monitoring
y When the following relay cables are used, respiration cannot be
measured.
・
Relay Cable CI
‐
700E-3 (defibrillation/electrosurgery-proof, 3-electrode)
・ Relay Cable CI ‐ 700E-4 (defibrillation/electrosurgery-proof, 4-electrode)
・
Relay Cable CI
‐
700E-5 (defibrillation/electrosurgery-proof, 5-electrode)
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.

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 or skin fit appears with the sensor use,
change the attachment site or stop using the sensor.
y 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.
y Even a short duration of attachment may inhibit the blood flow and
generate compression necrosis and burn injury.
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 skin for 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 a measurement error.
Place a black or dark cloth over the sensor.
