The purpose of this clinical study is to validate the SpO2 accuracy of the BiOSENCY BORA BAND™ wristband Pulse Oximeter during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry. The end goal is to provide supporting documentation for the SpO2 accuracy validation of BORA BAND™ wristband Pulse Oximeter.

It is required that the Accuracy Root Mean Square (ARMS) performance of the BORA BAND™ wristband Pulse Oximeter will meet a specification of 3.5 or better in non-motion conditions for the range of 70 - 100% SpO2 thereby demonstrating an acceptable SpO2 accuracy performance specification.

The SpO2 accuracy performance of BiOSENCY BORA BAND™ wristband Pulse Oximeter will be evaluated during non-motion conditions over the range of 70-100% SaO2 and compared to arterial blood samples assessed by CO-Oximetry. A minimum of 10 healthy adult male and female subjects, ranging in age and pigmentation from light to dark, will be enrolled in the study to meet the study design requirements defined by ISO 80601-2-61:2017 and by the FDA's Guidance for Pulse Oximeters (March 4, 2013). The subjects will have an arterial catheter placed in the radial artery to allow for simultaneous blood samples during stable plateaus of induced hypoxic levels. The investigational device will be placed on the wrist opposite for the test per the instructions for use. Simultaneous data collection will be set up for the system under test and control oximeter.

For the data analysis, the control oximeter will be used to assess the stability of each data point. Data that is found to be unstable will be removed prior to the comparative analysis. The CO-Oximeter data will be reviewed to make sure it does not contain any anomalous values such as elevated, low or inconsistent COHb, MetHb, or tHb data. Anomalous values will be removed from the analysis prior to pairing of the SpO2 and SaO2 data. The statistical analysis is performed on a minimum of 200 data points collected from at least 10 subjects for the range of 70% to 100% SaO2 with allowance of ± 3% of the target range. Functional SaO2 as measured by Reference CO-Oximetry will be used as the basis for comparison. The Accuracy Root Mean Square (ARMS) calculation is used to determine the SpO2 accuracy performance. Success will be achieved with an ARMS of 3.5 or better showing equivalence to the Gold Standard Reference CO-Oximetry providing documentation to support SpO2 accuracy claims for the investigational device.

The study population will include 10-15 healthy non-smoking (or has refrained from smoking for 2 days) competent adults, 18-50 years of age. The subject selection will be an equitable distribution of males and females of any race with varying skin tones including at least 2 darkly pigmented subjects or 15% of the subject pool, whichever is larger. The subjects must understand the study and consent to participate by signing the Informed Consent Form. The subjects must be healthy showing no evidence of medical problems as indicated by satisfactorily completing the health assessment form.
