简要总结
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.

Experimental
All subjects are enrolled into the test group and all subjects received the Rainbow Resposable Adhesive Sensors.
干预措施: Rainbow Resposable Adhesive Sensors (Device)
结局指标
主要结局
Accuracy of Sensor by Arms Calculation
时间窗: 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.
