7) Sensor temperature. (Maintain the temperature between +28 ℃ (+82.4 °F) and +41 ℃ (+105.8 °F)
for best operation)
8) Placement of the sensor, such as on an extremity that has a NIBP cuff, arterial catheter, or
intravascular line.
9) Significant concentrations of dysfunctional hemoglobin, such as carboxyhemoglobin and
methemoglobin.
10) External illumination more than 5,000 lumens/square meter (typical office lighting). (Cover the
sensor site with opaque materials is recommended.)
11) Venous pulsations.
12) When the application site for the sensor is deeply pigmented or deeply colored, for example, with
nail polish, artificial nails, dye, or pigmented cream.
13) Another SpO2 sensor in close proximity (e.g. when more than one SpO2 measurement is
performed on the same patient). Always cover both sensors with opaque material to reduce
cross-interference.
To use the sensor:
a) Select an appropriate sensor. Use the SpO
2
transducers approved by the manufacturer.
b) Apply the sensor as directed, and observe all warnings and cautions presented in the sensor user
manual.
c) Clean and remove any substances, such as nail polish, from the application site.
d) Periodically check to ensure that the sensor remains properly positioned on the patient.
e) Cover the sensor site with opaque material.
8.2.2 Monitoring Procedure
1) Depending on the equipment you are using, insert the SpO
2
sensor plug into the SpO
2
socket on the
monitor or the FT20 Telemetry Transmitter.
2) Place the forefinger, middle finger or third finger into the SpO
2
sensor.
NOTE:
1 The nail should cover the light but not too long.
2 The cable should be placed on the backside of the hand.
3 Avoid external light sources such as radiated rays or ultrared rays.
8.2.3 Enabling SpO
2
Trace Printing
The real-time SpO
2
measurement result is displayed in the parameter area of the main interface. You
can choose to print them as a continuous trace on the recorder paper (refer to figure 5-1).
To enable or disable SpO
2
trace printing,
1 Select the main menu key on the main interface.
2 Select Recorder > SpO
2
Trace.
3 Select ON or OFF (default).
4 Select OK.
8.2.4 Assessing the Validity of a SpO
2
Reading
You can check the quality of the pleth wave and the stability of the SpO
2
values to assess whether the
sensor functions properly and whether the SpO
2
readings are valid. Always use these two indications
simultaneously to assess the validity of a SpO
2
reading.
NOTE:
1 The SpO
2
accuracy has been validated in human studies against arterial blood sample
