8.4 Limitations of Measurement

In operation, the accuracy of oximetry readings can be affected by:
High-frequency electrical noise, including noise created by the host system, or noise from
external sources, such as electrosurgical apparatus, which is admitted by the host system.
Do not use monitor and oximetry sensors during magnetic resonance imaging (MRI)
scanning. Induced current could potentially cause burns.
Intravenous dye
Excessive patient movement
Outside ray radiation
Improper sensor application
Sensor temperature (maintain between +28 °C and +42 °C for best operation )
Placement of the sensor on an extremity that has a blood pressure cuff, arterial catheter, or
intravascular line
Significant concentration of dysfunctional hemoglobin, such as carboxyhemog-lobin and
methemoglobin
Low SpO
2
Circular perfusion is not good for test part
It is recommended to use SpO
Information.
The dissipation power is less than 50 μW, when the sensor temperature is higher than +41
you should shorten the measuring time.
