Overview

Brief Summary

In this study, the concentration of hemoglobin within the subject's blood will be reduced in a controlled manner by administering fluids intravenously. The accuracy of a noninvasive hemoglobin sensor(s) will be assessed by comparison to hemoglobin measurements from a laboratory analyzer.

Outcomes

Primary Outcomes

Accuracy of Sensor by Arms Calculation

Time Frame: 1-3 hours

Accuracy will be determined by comparing the noninvasive hemoglobin measurement of the pulse oximeter to the hemoglobin value obtained from a blood sample and calculating the arithmetic root mean square(Arms) error value.
