Chapter 11 Monitoring Temperature
11.1 Introducon
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-heang, the voltage across the thermistor
is measured, and further converted to the temperature reading according to the temperature-resistance characterisc
for a specic type of thermistor. The temperature measuring circuit does the self-tesng periodically to prevent false
reading when there is failure in hardware.
You can simultaneously monitor two temperature sites using the device, for specic model, only one channel temperature
is available.
11.2 Safety Informaon
Verify that the probe detecng funcon works correctly before monitoring. Unplug the temperature probe cable
from the T1 or T2 connector, and the monitor can display the message [T1 Sensor O] or [T2 Sensor O] and give
alarm tones correctly.
Make correct choice in setup menu for “KRK” and “YSI” series of temperature sensor used, since they have dierent
temperature-resistance characterisc (KRK thermistor has 10.000K ohms @25
o
C, YSI thermistor has 2.252K ohms
@25
o
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.
Connecng the thermal temperature sensor:
The temperature sensor is thermo-resistor type it needs me to respond the temperature change, so the accurate
temperature value displays aer a while. The temperature sensor equipped may have dierent shape for measuring body
surface temperature or cavity temperature respecvely.
Normal value for body surface: 36.5°C ~37°C;
Notes:
For body surface temperature probe, aach the TEMP sensor to the paent, 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 x it with adhesive tape to make them contact rmly.
Especially for pediatric paent, they have more acvies, pay more aenon to the sensor xing.
The TEMP sensor is designed for use with the specic paent monitor, which cannot be used as applied part to
other products.
The operator is responsible for checking the compability of the paent monitor and sensor type including cable
before use.
Incompable components can result in degraded performance.
