Patients with a \u226520% decline in the right rSO2 were older and had a higher baseline mean arterial pressure (MAP) and longer cardiopulmonary bypass (CPB) times. Patients with a \u226520% decline in the left rSO2 had a higher baseline MAP. Age, baseline MAP, female sex and CPB time for the right rSO2 and baseline MAP values and female sex for the left rSO2 values were positively associated with a \u226520% decline in univariate logistic regression analyses. Baseline MAP and CPB time for the right rSO2 values and baseline MAP for the left rSO2 values retained their statistical significance in multivariate logistic regression analyses. Activated clotting time (ACT) showed a statistically significant and inverse relationship with the left rSO2 values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Higher baseline MAP values for right and left rSO2 values and longer CPB times for right rSO2 values were independently associated with a \u226520% decline.
