accuracies are expressed as plus or minus “X” digits (saturation
percentage points) between saturations of 70–100%. This variation equals
plus or minus one standard deviation (1SD), which encompasses 68% of
the population. All accuracy specifications are based on testing the
subject monitor on healthy adult volunteers in induced hypoxia studies
across the specified range. Adult accuracy is determined with
Oxisensor® II D-25 sensors.
