Trial Title: Role of Absolute Cerebral Oximetry to Prevent Neurocognitive Injury in Elderly Patients Undergoing Cardiac Surgery

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* 65 and older~* Elective cardiac or thoracic aortic surgery~* Capable and willing to consent~* Participants literate in English~Exclusion Criteria:~* Emergency Surgery~* Major Neurological Disease~* Gross Cognitive Dysfunction~* Patients not expected to be able to complete the 1 week and 3 months post-operative visit.

- Gender: ALL
- Minimum Age: 65 Years
- Maximum Age: None
- Healthy Volunteers: t

Study Arms:
- Cerebral Desaturation, i.e; SctO2 < 60 % for 5 minutes (Type: ACTIVE_COMPARATOR): Once the cerebral desaturation is established, the study personnel will attempt to optimize the level of oxygen within the brain of the study patients.
- Patients with SctO2 less than 60 %. (Type: NO_INTERVENTION): The study patients will not get any intervention in this arm if the Sct02 falls below 60%

Based on this trial design, predict the completion outcome and termination type (if applicable).
