CAUTION
When monitoring respiration is needed,
measure respiration with an
instrument. The transmitter calculates
SpO
2
of arterial blood based on the
principle of pulse oximeter and does
not measure respiration.
CAUTION
When monitoring SpO
2
only, detection
of arrhythmia and asystole is not
available and arrhythmia alarms such
as ASYSTOLE, VF or VT are not
available. If the patient requires ECG
monitoring, monitor the ECG.
CAUTION
When monitoring SpO
2
only (without
ECG monitoring), turn on both the
upper and lower limit alarms for PR
and SpO
2
on the receiving monitor. If
the patient’s pulse is not detected
during asystole or other condition, a
“CANNOT DETECT PULSE” or
“CHECK PROBE” alarm occurs instead
of an SpO
2
limit alarm. Furthermore, if
the patient has no pulse, noise from
probe movement could be misjudged
as a pulse and cause an incorrect PR
or SpO
2
value to be displayed.
Output Signal
WARNING
Do not use the output signal from the receiving monitor as the synchronization signal
for other equipment such as IABP, MRI, echocardiography or defibrillator. There may
be time delay between the monitor and the other equipment caused by waveform
transmission delay and spike noise may interfere on the output signal and be
mistaken as a trigger.
