Key result
Systemic venous saturation correlated poorly with jugular bulb venous saturation during cardiopulmonary bypass (r=0.29, p=0.0005), indicating it is a poor indicator of cerebral perfusion.
Why the study?
Does systemic venous saturation correlate with jugular bulb venous saturation during cardiopulmonary bypass?
Observational
Does systemic venous saturation correlate with jugular bulb venous saturation during cardiopulmonary bypass?
Effect estimate: r = 0.29
p-value: p=0.0005
Systemic venous saturation is a poor indicator of cerebral saturation during cardiopulmonary bypass, highlighting the need for specific cerebral oxygenation monitoring.

Systemic SvO2 may not reflect cerebral oxygenation on CPB; leaves open whether jugular monitoring improves outcomes.
Croughwell et al. (1995) conducted an observational in Cardiopulmonary bypass. Systemic venous oxygen saturation vs. Jugular bulb venous saturation was evaluated on Correlation of jugular bulb and systemic venous saturation at stable hypothermia (cold 1) (r = 0.29, p=0.0005). Systemic venous saturation correlated poorly with jugular bulb venous saturation during cardiopulmonary bypass (r=0.29, p=0.0005), indicating it is a poor indicator of cerebral perfusion.
