1. The reference for accuracy testing is an N-200 oximeter and D-25
sensors that have been validated in human blood studies against
an Instrumentation Laboratories CO-Oximeter. Adult accuracy
specification is based on testing with D-25 sensors; neonatal
accuracy specification is based on testing with N-25 sensors. For
specifications with other NELLCOR sensors, see the sensor
directions for use.
2. This variation equals one standard deviation (SD). Plus or minus
one SD encompasses 68% of the population.
