1. GENERAL
ECG Monitoring
CAUTION
••
••
• If there is any doubt about the arrhythmia analysis, make the central
monitor relearn the patient’s VPC. Otherwise, an important
arrhythmia may be overlooked.
••
••
• The central monitor does not perform ECG analysis. Therefore, the
QRS sound at the central monitor may not synchronize with patient’s
actual QRS when complicated arrhythmias occur or during pacing.
••
••
• The ST level transmitted from a transmitter is not designed to be
accurate enough for diagnosis. Do not rely on the ST level displayed
on the central monitor.
••
••
• The QRS sound at the central monitor has a delay of approximately
several seconds because of network connection.
••
••
• When the full disclosure waveform is expanded to actual size, it may
be distorted because it has been compressed then expanded. When
reading the expanded ECG waveforms, be aware of this distortion.
••
••
• Turn the pacing detection to ON when monitoring a pacemaker
patient. Otherwise QRS and pacemaker spike may not be
distinguished and pacemaker failure may not be recognized.
NIBP Measurement
WARNING
••
••
• When performing long term measurements at intervals less than 2.5
minutes, periodically check the state of the patient, blood vessels
and limb for adequate circulation. Congestion may occur at the
measurement site.
••
••
• When performing periodic measurements for a long term,
periodically check the circulation condition.
CAUTION
Before you remotely start and stop NIBP measurement from the central
monitor, confirm the state of the patient at the bedside monitor.
Carefully start and stop NIBP measurement from the central monitor.
