Accuracy of Owlet Smart Sock Sensor 3rd Generation With Profound Hypoxia

Completed

• Conditions: Hypoxia

• Registration Number: NCT04446247
• Lead Sponsor: Owlet Baby Care, Inc.

Brief Summary

Performance testing of pulse oximeters. The protocol involves brief stable arterial oxygen desaturation in healthy volunteers and sampling arterial blood when a stable level of hypoxia has been attained. The blood sample is analyzed for oxygen saturation with a gold standard bench CO-oximeter. This protocol is aligned with the latest ISO and FDA guidance documents for pulse oximeter testing.
