SpO MEASUREMENT FUNCTION(OPTIONAL)
2
Precautions during SpO2 Measurement:
Note
• Make sure the nail covers the light. The probe cable should be on the backside of the hand. Improper probe placement
or improper contact with the test site will influence the measurement.
• SpO value always displays in the fixed place.
2
• Data averaging and signal processing will delay the SpO
measurement data is less than 30 seconds, when signal attenuation, weak perfusion or other interference appears, it will
result in time increasing of dynamic data averaging, which depends on the PR value.
• The PLETH waveforms are not normalized, which is used as the indicator for signal incompleteness. So the accuracy of
the measured values may decrease when the waveform does not tend to smooth and stable. When the waveform tends
to smooth and stable, the reading is optimal value, and the waveform at the moment is the most standard one..
• The temperature for the contact surface of the device with the body is less than 41℃, and this temperature value is
measured by a temperature measuring device.
• The device does not provide over-limit prompt function, so it is inapplicable for using in places where need such function.
• The SpO probe has been calibrated before leaving factory. It does not need to be calibrated during maintenance.
2
• SpO probe is calibrated to show functional oxygen saturation.
2
• The SpO probe and photoelectric receiving tube should be arranged in a way with the subject's arteriole in a position
2
there between. Make sure the optical path is free from any optical obstacles like rubberized fabric, to avoid inaccurate
measurement.
• As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of subject is required. For a
subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting
drug, the SpO waveform (PLETH) will decrease. In this case, the measurement will be more sensitive to interference.
2
• The accuracy of the readings under weak perfusion has been verified using signals from the patient simulator. The SpO
and pulse rate values vary within the measurement range due to various weak signal conditions and are compared to
the actual SpO and pulse rate values of the known input signals.
