Accuracy of Noninvasive Pulse Oximeter Measurement of Hemoglobin for Rainbow DCI Sensor

Not Applicable

Completed

• Conditions: Surgery; Healthy
• Interventions: Device: DCI pulse oximeter sensor

• Registration Number: NCT03124901
• Lead Sponsor: Masimo Corporation

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Test Group	DCI pulse oximeter sensor	All subjects are enrolled into the test group and all subjects receive DCI pulse oximeter sensor.

Primary Outcome Measures

Name	Time	Method
Accuracy of Sensor	Up to 24 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.
