NOTE: When multiple alarms of different levels occur simultaneously, the
pulse oximeter will select the alarm of the highest level and give visual
and audible alarm indications accordingly.
5.6 Measurement Limitations
If you doubt the SpO2 measurements, check the patient's vital signs
first. Then check the pulse oximeter and SpO2 sensor. The following
factors may influence the accuracy of measurements:
6 Summary of Spo2 & pulse rate accuracy testing
1) According to ISO80601-2-61, the 300 data pairs (SPO2 VS SaO2)
were obtained throughout the hypoxia breathe-down trials in all 12
volunteers.The SpO2 accuracy specification in the range of 70% to
100%,70% to 80%, 80% to 90%, and 90% to 100% is as the
following table:
Pulse
Oximeter
SPO2
Sensor
Arms
100%-70%
100% – 90% 90% - 80% 80% - 70%
2) The data from the hypoxia breathe-down trials for each of the 12
volunteers is summarized in Figures 1&2:

Ambient light
Physical movement (person or imposed motion)
Diagnostic testing
Low perfusion
Electromagnetic interference, such as MRI environment
Electrosurgical units
Dysfunctional hemoglobin, such as carboxyhemoglobin (COHb) and
methemoglobin (MetHb)
Presence of certain dyes, such as methylene and indigo carmine
Drop of arterial blood flow to unmeasurable level due to shock, anemia, low
temperature or vasoconstrictor.
Inappropriate positioning of the SpO2 sensor, or use of incorrect SpO2
