Accuracy, A
rms
(root mean square of paired values; previously represented by ± 1 SD):
70 to 100% ± 2 digits (without motion)
70 to 100% ± 3 digits (during clinical motion)
1
70 to 100% ± 2 digits (during clinical low perfusion)

measurement accuracy is based on deep hypoxia studies using OxyTip+
sensors on volunteer subjects. Arterial blood samples were analyzed simultaneously
on multiple CO-oximeters.
NOTE: Accuracy may vary for some sensors; always check the instructions for the
sensor.
