SpO2 MEASUREMENT FUNCTION
(This chapter is only suitable for European Union market)
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 inuence the measurement.
• SpO2 value always displays in the xed place.
• The test site shall not use external coloring agent (such as nail polish, dyestuff or color skin care products, etc.), otherwise
it will affect the measurement.
• The ngers which are too cold or too thin may affect the measure accuracy, please insert the thicker nger such as thumb
or middle nger deeply enough into the probe.
• The SpO2 probe is suitable for children and adults (not suitable for infants and newborns). The device may not applicable
for all patients. If you are unable to achieve stable readings, stop using it.
• Data averaging and signal processing will delay the SpO2 displaying and data values transmitting. The update time of
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 alarm function, so it is inapplicable for using in places where need such function.
• The SpO2 probe has been calibrated before leaving factory. It does not need to be calibrated during maintenance.
• SpO2 probe is calibrated to show functional oxygen saturation.
• The SpO2 probe and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a position
there between. Make sure the optical path is free from any optical obstacles like rubberized fabric, to avoid inaccurate
measurement.
