Test methods used to establish SpO
hypoxia studies with healthy non-smoking adult volunteers over the specified SpO
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
simulator with 0.3% signal amplitude.
