SpO2
Unit of measure %
Measurement range 1% to 100%
Nellcor sensor accuracy guide SpO2 measurement accuracy can only be evaluated in vivo
by comparing pulse oximeter readings with SaO2
measurements obtained from simultaneously sampled
arterial blood made using a laboratory CO-oximeter. SpO2
accuracy was validated through breathe-down-equivalent
testing by Covidien using electronic measurements to prove
equivalence to the Nellcor N600x predicate device. The
Nellcor N600x predicate device was validated by performing
human-subject, “breathe-down” clinical trials.
Accuracy
Note Saturation accuracy varies by sensor type.
The worst case accuracy range of the
module or the attached sensor will apply.

Electrical/Optical Specifications Nellcor pulse oximetry sensors contain light-emitting diodes
(LEDs) that emit red light at a wavelength of approximately
660 nm, and infrared light at a wavelength of approximately
900 nm. The total optical output power of the sensor LEDs is
