2. Problem Cardiopulmonary Bypass (CPB)
Definition - Pros and Cons

3. Problem - Current Practices
Post-oximetry on the finger or ear for oxygen levels
Not the most accurate method
Blood drawn from an artery is the most accurate method
Jugular Venous Bulb (JVB) catheter
Substitute: Urinal catheter
But how do we monitor brain activity during cardiac surgery?
