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.

Arm Intervention/treatment
Experimental: Noninvasive Hemoglobin Sensor
All subjects are enrolled into the test group and all subjects received the Noninvasive Hemoglobin Sensor (Rainbow Reusable DCI, DCIP)
Device: Hemoglobin Sensor ((Rainbow Reusable DCI, DCIP))
Measurement of Noninvasive Hemoglobin (SpHb)

Primary Outcome Measures :
  1. Accuracy of Sensor by Arms Calculation [ Time Frame: 1-5 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.
