15. Specification
85
LX-7230KM
SpO
2
Measurement Range: 0 to 100%
Resolution: 1%
Measurement Accuracy: Accuracy of measurement with SpO
2
probe
is as follows.
Measurement Spot
Measurement Accuracy
(±1SD)
Finger ±2%
Big toe or the root
of the big toe
±3%
(When SpO
2
is 70 to 100%. Less than 70% is not specified.)
Wavelength: 658 to 665nm (Red light), 860 to 925nm
(infrared light)
Power Loss on Probe: 2.0mW
Measurement Reply Time: 12 sec (moving average time)
Measurement Value Update Rate: Continuous mode 1 second
Intermittent mode 25 seconds
NOTE
The SpO
2
measurement accuracy is determined based on the values of
the root-mean-square (rms) difference between SpO
2
readings of the pulse
oximeter equipment and values of SaO
2
determined with a CO-oximeter,
by healthy adult volunteers. The pulse oximeter equipment measurements
are statistically distributed; ±2% measurement accuracy means that only
about two-thirds of pulse oximeter equipment measurements can be
expected to fall within ±2% of the value measured by a CO-oximeter.
