Description
CAUTIONS
Monitor performance:
Place the sensor so that the LEDs and the photodiode are opposite each 
other.
Monitor performance:
When an SpO
2
 sensor is located on the same limb as the NIBP cuff, SpO
2
 
readings will not be valid while the cuff is inflated. If valid SpO
2
 readings 
are required during the entire blood pressure determination, attach the 
SpO
2
 sensor to the limb opposite the one with the blood pressure cuff.
NOTES
A patient’s vital signs may vary dramatically during the use of 
cardiovascular agents such as those that raise or lower blood pressure or 
those that increase or decrease pulse rate.
SpO
2
 and pulse rate values are filtered by an averaging technique, which 
determines how quickly the reported values respond to changes in the 
patient’s saturation. Increased averaging time effects time to alarm for SpO
2
 
saturation and pulse rate limits.
Pulse rate measurement is based on the optical detection of a peripheral 
flow pulse and therefore may not detect certain arrhythmias. The pulse 
oximeter should not be used as a replacement or substitute for ECG based 
arrhythmia analysis.
Software development, software validation, and risk and hazard analysis 
have been performed to a registered quality system.
A functional tester cannot be used to assess the accuracy of a pulse 
oximeter probe or a pulse oximeter monitor.
The pulse oximeter cannot distinguish between oxyhemoglobin and 
dyshemoglobins.
Poor perfusion may affect the accuracy of measurement, especially when 
using an ear sensor.
Check that the red light is lit in the sensor.
Check that the waveforms (if enabled in monitor setup) and parameter 
values are displayed when the sensor is connected to the patient.
