MONITORING TEMPERATURE
11.1 Introduction
The body temperature is monitored by direct measuring mode with the temperature sensor of thermistor type.
Very small amount of constant current is applied to the temperature sensor to avoid self-heating, the voltage
across the thermistor is measured, and further converted to the temperature reading according to the temper-
ature-resistance characteristic for a specific type of thermistor. The temperature measuring circuit does the
self-testing periodically to prevent false reading when there is failure in hardware.
You can simultaneously monitor two temperature sites using the device, for specific model, only one channel
temperature is available.
11.2 Safety Information

Verify that the probe detecting function works correctly before monitoring. Unplug the temperature probe
cable from the T1 or T2 connector, and the monitor can display the message [T1 Sensor Off] or [T2 Sensor
Off] and give alarm tones correctly.

Make correct choice in setup menu for “KRK” and “YSI” series of temperature sensor used, since they have
different temperature-resistance characteristic (KRK thermistor has 10.000K ohms @25°C, YSI thermistor
has 2.252K ohms @25°C). Mismatching will cause wrong temperature reading or even out of range.
11.3 Making a TEMP Measurement
Please follow the corresponding methods to make temperature measurement according to the temperature
transducer you selected.
• Connecting the thermal temperature sensor:
The temperature sensor is thermo-resistor type it needs time to respond the temperature change, so the accu-
rate temperature value displays after a while. The temperature sensor equipped may have different shape for
measuring body surface temperature or cavity temperature respectively.
Normal value for body surface: 36.5°C ~37°C;
Notes:
�
For body surface temperature probe, attach the TEMP sensor to the patient, generally if the TEMP sensor
and skin doesn’t contact closely, the measured value becomes lower, so for those who have requirement
for temperature monitoring, add a proper pad to the sensor and fix it with adhesive tape to make them
contact firmly.
�
Especially for pediatric patient, they have more activities, pay more attention to the sensor fixing.
�
The TEMP sensor is designed for use with the specific patient monitor, which cannot be used as applied
part to other products.
�
The operator is responsible for checking the compatibility of the patient monitor and sensor type including
cable before use.
�
Incompatible components can result in degraded performance.
No. Event Alarm level Remark
1 SpO

INOP
High priority
alarm
Such alarm will not display on alarm informa-
tion area, but it will be recorded as alarm event
which can be reviewed on “Alarm event”. these
events are mostly unrecoverable faults.
2 SpO

firmware error
3 Communication error
4 SpO
2
faulty sensor
5 SpO
2
hardware error
6 SpO
2
module error
7 SpO
2
sensor error It means the SpO
2
sensor identifications fails.
8 SpO
2
sensor disconnected
Medium
priority alarm
The sensor cable or extension cable is not con-
nected to the monitor.
9 SpO
2
probe off
It means the sensor cable is connected, but the
probe is out of the measuring site.
