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.

研究组 & 干预措施
Noninvasive Hemoglobin Sensor
Experimental
All subjects are enrolled into the test group and all will receive the pulse oximeter sensor.
干预措施: Pulse Oximeter sensor (Device)
结局指标
主要结局
Accuracy of Sensor by Arms Calculation
时间窗: 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.
