NCT05685654

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.

Outcome Measures

Primary Outcomes (3)

  • SpO2 root mean square accuracy of the Norbert Device

    SpO2 root mean square accuracy will be calculated following FDA guidelines.

    Up to 1 hour

  • SpO2 bias of the Norbert Device

    SpO2 bias calculation of the Norbert Device will follow the FDA guidelines for analyzing population mean bias, between-subject variance, and within-subject variance.

    Up to 1 hour

  • Bland-Altman plots with linear regression line and 95% upper and lower limits of agreement

    A method comparison study will be analyzed with a Bland-Altman plot. This study will produce limits of agreement (LoA) and associated confidence intervals from the two measurements obtained on each subject. The conclusion that the two measurements are in agreement depends on whether the confidence intervals constructed from the data are within the boundaries set from the maximum allowable difference.

    Up to 1 hour

Interventions

The Norbert Device (ND) is a contactless, noninvasive device that provides measurements of body temperature, oxygen saturation (SpO2), and pulse rate.

  • Prior known severe allergies to medical grade adhesive/tape (Band-Aid)
  • Taking any medication other than birth control
  • Is currently participating in, or has recently participated in (discontinued within 30 days prior to the hypoxia procedure for this study) in an investigational interventional drug, device, or biologic study
  • Has a negative Allen's Test to confirm non patency of the collateral artery
  • Has made a whole blood donation or has had at least 450 ml of blood drawn within 8 weeks prior to the study procedure
  • Is female with a positive urine pregnancy test, or is female and is unwilling to use effective birth control between the time of screening and study procedure or is breast feeding
  • Has anemia
  • Has heparin allergy
  • Has a history of sickle cell trait or thalassemia \[self-reported\]
  • Has a positive urine cotinine test or urine drug screen or oral ethanol test
  • Has a room air saturation less than 95% by pulse oximetry
  • Has a clinically significant abnormal EKG
  • Has a COHb greater than 3%, or MetHb greater than 2%
  • Students and Employees under the direct supervision of PI or Sub-I
