NCT ID: NCT05685654

Last Updated: 2023-01-23

Basic Information

• Recruitment Status: UNKNOWN
• Total Enrollment: 15 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2023-03-31
• Study Completion Date: 2023-03-31

Brief Summary

The purpose of this study is to evaluate the SpO2 accuracy and performance of the Norbert Device during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-oximetry for SpO2 validation.

Detailed Description

The study is a single center, prospective, non-randomized study to measure the accuracy of an investigational device compared to blood reference values. The design of the study will be conducted in accordance with the recommendations of ISO 80601-2-61:2011 Annex EE.2 Procedure for invasive laboratory testing on healthy volunteers. The purpose of this study is to evaluate the SpO2 accuracy and performance of the Norbert Device during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-oximetry for SpO2 validation. The end goal is to show the SpO2 accuracy performance of the Norbert Device. It is expected that the Accuracy Root Mean Square (Arms) performance of pulse oximeters will meet a specification of 3.5 or better in non-motion conditions for the range of 70-100% SaO2 thereby demonstrating an acceptable SpO2 accuracy performance specification.
