1.Measurement principle
The Oximeter displays functional oxygen saturation. The oximeter’s algorithm uses the
Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobin
(RHb) and Oxyhemoglobin (O2 Hb) in glow and near-infrared zones. Operation principle
of the instrument is Photoelectric Oxyhemoglobin Inspection Technology is adopted in
accordance with Capacity Pulse Scanning and Recording Technology, so that two beams of
different wavelength of lights (660nm glow and 880nm near infrared light) can be focused
onto human nail tip through perspective clamp fi nger-type sensor. Then measured signal
can be obtained by a photosensitive element, information acquired through which will be
shown on two groups of LEDs through process in electronic circuits and microprocessor.
2.Precautions for use
• Operation of 18710 may be affected by the use of an electrosurgical unit (ESU).
• The 18710 must be able to measure the pulse properly to obtain an accurate SpO2
measurement. Verify that nothing is hindering the pulse measurement before replying on
the SpO2 measurement.
• Do not use the 18710 in an MRI or CT environment
• Do not use the 18710 in situations where alarms are required. The device has no alarms.
• Explosion hazard: Do not use the 18710 in an explosive atmosphere.
• The 18710 is intended only for non-medical use for healthy people to monitor their pulse
and blood oxygen levels while exercising.
