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.

Measurement and display range: 30 to 250 beats per minute (bpm)
Display resolution: 1 bpm
First reading, full accuracy: ≤ 15 seconds
Accuracy
30 to 250 bpm: ± 2 digits or ± 2%, whichever is greater, (without motion)
30 to 250 bpm: ± 5 digits (during motion)
30 to 250 bpm: ± 3 digits (during low perfusion)
