6. TEMP MONITORING
6.1 Measurement Principle
The device measures temperature of body surface by taking advantage of the characteristics
of the thermal-sensitive resistor located in the temperature probe, whose impedance varies
with the body temperature. The monitor measures the impedance of the resistor and then
consults a resistance-temperature table stored in the device beforehand. The current
temperature is found in the table and displayed on the LCD screen.
The monitor has only one TEMP measurement channel for measuring the body surface
temperature of the patient.
6.2 Measurement Steps
The monitor uses a body surface TEMP probe to measure the patient’s body temperature.
Disposable or reusable probe can be selected according to your requirement. Please follow
the steps below to use the body surface TEMP probe:
1.
Insert the probe’s connector to the monitor’s TEMP socket ;
2.
Attach the probe to an appropriate site on the patient’s body;
3.
Turn on the monitor. The LCD screen will display the parameter monitoring screen;
4.
Wait until the measurement does not change frequently, the stable readings will
be displayed on the LCD screen.
NOTE: Because the temperature sensor’s impedance varies slowly with the temperature
of the body, an accurate result of temperature measurement is usually obtained after
monitoring for more than 5 minutes.
6.3 Precautions
WARNING
•
Check if the probe cable is in normal condition before monitoring. Do not use the
TEMP probe once the package or the probe is found damaged.
•
Remove the TEMP probe from the patient after measurement.
•
As with any medical equipment, carefully route patient cabling to reduce the
possibility of patient entanglement or strangulation. Cables of electrical surgical
equipment should not be winded around that of the TEMP probe.
•
If the reading is unreasonable, first check the patient’s condition, and then check the
probe installation and connection with the monitor, finally ask the qualified engineer to
check the device and the SPO2 sensor for proper functions.
•
Do no reuse disposable TEMP probes.
•
When used on different patients, the monitor is prone to crossed contamination, which
should be prevented and controlled by the user. Disinfection is recommended before
using the TEMP probe on other patients.
CAUTION: Hold the probe and cable carefully and lightly. If not use it, you should coil up
the probe and cable into a loose circle. If the wire inside the cable is tensely pulled, it
may cause mechanical damage to the probe and the cable.
