Accuracy of Noninvasive Hemoglobin Sensor (Rainbow Reusable DCI)

Study Overview
=================
Brief Summary
-----------------
In this study, the accuracy of a noninvasive hemoglobin sensor(s) will be assessed by comparison to hemoglobin measurements from a laboratory hematology analyzer. Blood samples are collected from healthy volunteers who are enrolled in either a blood draw procedure or a hemodilution procedure wherein blood is repeatedly sampled as the concentration of hemoglobin is reduced in a controlled manner by administering fluids intravenously.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accuracy of Sensor by Arms Calculation | 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. | 1-5 hours |
