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.

Arm Intervention/treatment
Experimental: Rainbow Resposable Adhesive Sensors
All subjects are enrolled into the test group and all subjects received the Rainbow Resposable Adhesive Sensors.
Device: Rainbow Resposable Adhesive Sensors
Noninvasive Measurement of SpHb

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