Trial Outcomes & Findings for Rainbow DCI vs. R1-25 Sensor SpHb Sub-Range Performance Equivalence (NCT NCT03157232)

NCT ID: NCT03157232

Last Updated: 2017-07-27

Results Overview

Sub-range performance equivalence was determined by comparing the noninvasive hemoglobin measurement of the pulse oximeter sensor to the hemoglobin value obtained from a blood sample and calculating the arithmetic root mean square (Arms) error value.In order to obtain the Arms value, the blood sample hemoglobin value is subtracted from the pulse oximeter hemoglobin value for a number of samples, the average of this difference is computed as the bias. The standard deviation of these differences is computed as the precision. The square root of the sum of the squares of bias and precision is computed as the Arms Error value.
