Prior known severe allergies to medical grade adhesive/tape (Band-Aid) [self-reported]; 3. Taking any medication other than birth control [self-reported]; 4. Is currently participating in, or has recently participated in (discontinued within 30 days prior to the hypoxia procedure for this study) in an investigational drug, device, or biologic study [self-reported]; 5. Has a negative Allen's Test to confirm non-patency of the collateral artery [clinical assessment by PI or delegate]; 6. Has made a whole blood donation or has had at least 450 ml of blood drawn within 8 weeks prior to the study procedure [self-reported]; 7. Is female with a positive pregnancy test [serum or urine], or is female and is unwilling to use effective birth control between the time of screening and study procedure or is breastfeeding; 8. Has anemia [lab values specific for gender]; 9. Has a history of sickle cell trait or thalassemia [self-reported]; 10. Has an abnormal hemoglobin electrophoresis test [lab measurement]; 11.

Primary | Validated the Next Generation Oximeter | Cerebral overall mean bias (percentage saturation) defined as the average of the differences between the regional saturation (rSO2) value and (fSO2) value obtained from simultaneous arterial and jugular venous blood samples. Cerebral trending is defined as the measurement of changes in regional saturation (rSO2) under conditions of changing fSO2. Cerebral trending mean bias is the average difference between changes in rSO2 values compared against changes in fSO2. Somatic trending mean bias is defined the same as Cerebral trending mean bias except for the location of measurement on the subjects and for Somatic trending mean bias, rS02 was compared to rSO2 on a commercially-available regional oximetry monitor. The smaller value the better performance. | Data collected from individual participant over 4 hour timeframe. |
