Cerebral Oxygen Saturation (Rso2) During Cardiopulmonary Bypass (CPB) Measured Using the INVOS Oximeter Closely Correlates with Baseline Rso2
Our findings suggest that low baseline rSO2 in patients with high BNP due to cardiac and/or renal diseases is more likely to result from tissue edema causing alterations in optical pathlength and thus in calculated rSO2 values, not readily modifiable with CPB, rather than actual cerebral hemodynamic alterations readily modifiable with CPB. These may partly explain why the INVOS oximeter is a trend monitor requiring baseline measures.

An Experience With Cardiopulmonary Bypass in HIV-Infected Patients
Having noted the good clinical status of some HIV patients who were referred for but refused surgery, we undertook surgery with the aim of determining outcome, risk-to-benefit ratio and, if possible, the effect of surgery with cardiopulmonary bypass (CPB) on the progression of their HIV disease.
