Table 1: Accuracy for sensors (Arms) *
* Because SpO
2
measurements are statistically distributed, only about 2/3 of the measurements can be expected to fall within
±
1 Arms of the value measured
by a CO-oximeter
Test methods used to establish SpO
2
accuracy: GE TruSignal SpO
2
measurement have been validated for no motion and motion accuracy in a controlled
hypoxia studies with healthy non-smoking adult volunteers over the specified SpO
2
range. SpO
2
readings were compared to SaO
2
values of drawn blood
samples measured by CO-oximetry. Subjects comprised both adult men and women and spanned a range of skin pigmentation.
** GE TruSignal technology have been validated for low perfusion SpO
2
accuracy over the specified range in a bench top testing against BioTek Index 2 patient
simulator with 0.3% signal amplitude.
