connector, be sure to hold the head of the connector firmly and pull.
2. The red blinking light inside the clip of the SpO
2
probe indicates a successful connection.
3. Insert one finger (index finger is preferred, the nail should be not too long) into the clip of the
probe according to the finger mark shown as below.
4. The device will begin to take the measurement.

Measurement Principle
SpO
2
measurement is based on dual wavelength opto-plrthysmometry technology, a unique
hardware and software design.
By use of red and infra-red light emitting through the patient’s finger, the photo-detector at the
other side senses the transmitted light and converts to current for later amplification and filte-
ring. The acquired light intensity signals (plethysmogram) are digitalized and further processed
with proprietary algorithm to determine the SpO
2
and pulse rate value.
Safety instructions for SpO
2
measurements
Continuous use of the SpO
2
probe may result in discomfort or pain, especially for those with
microcirculatory problems. It is recommended that the probe should NOT be applied to the
Figure 2.6 demonstration for SpO
2
probe
