简要总结
In this study, the concentration of hemoglobin within the subject's blood is affected by fluid status changes. The fluid status is affected by fluid loss during surgery for hospitalized study subjects or controlled administration of fluids intravenously for healthy study volunteers. The accuracy of a noninvasive hemoglobin sensor(s) will be assessed by comparing with blood sample analysis.

结局指标
主要结局
Accuracy of Sensor by Arms Calculation
时间窗: Up to 24 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.
