Purpose
The objective of this study is to validate Near-Infrared (NIRS) monitoring in patients undergoing circulatory arrest. This study will compare two-wavelength NIRS INVOS System, Somanetics; Troy, MI) with four-wavelength NIRS (Nonin Medical, Inc; Plymouth, MN) to determine which modality best correlates with jugular venous oxygen saturation

Primary Outcome Measures:
- Linear correlation between absolute value of cerebral oxygen saturation (rSO2) compared to Jugular Venous Oxygen Saturation (SjvO2). Sensitivity and specificity to detect < 60% desaturation. [ Time Frame: At the end of the surgical case approximately 6 to 8 hours ] [ Designated as safety issue: No ]

Criteria
Inclusion Criteria:
- Provide written informed consent from patient or legally authorized representative before surgery
- Adult patients 18-65 years of age
- Presenting for elective or urgent total aortic arch repair under moderate hypothermic circulatory arrest (Nasopharyngeal temperature 20 - 24 ºC) with selective antegrade cerebral perfusion -
