will be shown and a prompt "Probe Off" will appear in the status bar in the top of the display screen.
Note: The connector is also applied when uploading data to Med View software for reviewing. For detailed
information, refer to the instruction manual of Med View software.
After loading the time and ID number setting, plug your finger into the sensor as shown in the following
illustration.

4.3 Factors That May Affect Measurement
During operation, the accuracy of oximetry readings can be affected by the following factors.
4.3.1 Instrument performance depends on the pulsatile character of the artery. The measurement would not be
considered reliable and accurate if the following conditions are present during measurement.
Shock or cardiac arrest
o
Temperature of the digit
o
After the administration of a cardiovascular drug
o
Anemia
o
Evidence of ventilation-perfusion mismatch
o
4.3.2 Instrument performance depends on the wavelength absorption for oxyhaemoglobin and deoxyhaemoglobin.
If there are substances absorbing the same wavelength, this would induce false or low SpO
may affect these values.
carboxyhaemoglobin
o
methemoglobin
