Trial Outcomes & Findings for Accuracy of Noninvasive Pulse Oximeter Sensor (LNCS DBI) (NCT NCT03124979)

Results Overview

Accuracy will be determined by comparing the noninvasive blood oxygen saturation measurement of the pulse oximeter to that obtained from a blood sample and calculating the arithmetic root mean square(Arms) error value. In order to obtain the Arms value, the blood oxygen saturation measurement is subtracted from the pulse oximeter oxygen saturation measurement 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.
