6.3 Calibrating
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor
or sensor. Clinical testing is used to establish the SpO
2
accuracy. The measured arterial
hemoglobin saturation value (SpO
2
) of the sensors is compared to arterial hemoglobin
oxygen (SaO
2
) value, determined from blood samples with a laboratory CO-oximeter. The
accuracy of the sensors in comparison to the CO-oximeter samples measured over the SpO
2
range of 70%
~
99%. Accuracy data is calculated using the root-mean-squared (Arms value)
for all subjects, per ISO 9919:2005, Medical Electrical Equipment–Particular requirements for
the basic safety and essential performance of pulse oximeter equipment for medical use.
6.4 Trouble Shooting
a) The oximeter can’t be powered on
Please check the batteries. If you use the external power supply, please check if the power
supply is connected with oximeter properly.
b) “Probe off” alarm
Please check if the probe is connected with the oximeter correctly. If the sensor is with
extension cable please check if the extension cable is connected with the sensor correctly.
c) “No finger” alarm
Please check whether the sensor is correctly connected with patient’s finger.
