Why the study?

Can central venous oxygen saturation (ScvO₂) substitute for mixed venous oxygen saturation (SvO₂), and does SvO₂ reflect cardiac index?

Population

25 patients with pulmonary artery catheters inserted

Comparison

Measurement of central venous oxygen saturation vs Measurement of mixed venous oxygen saturation

Design

Cross-sectional

Overview

ScvO₂ may substitute for SvO₂ in monitored settings; leaves open whether either tracks cardiac index.

Structured PICO

Can central venous oxygen saturation (ScvO₂) substitute for mixed venous oxygen saturation (SvO₂), and does SvO₂ reflect cardiac index?

P
Population
25 patients with pulmonary artery catheters inserted (13 during general anesthesia, 12 in the intensive care unit for critical illnesses)
I
Intervention
Measurement of central venous oxygen saturation (ScvO₂)
C
Comparator
Measurement of mixed venous oxygen saturation (SvO₂)
O
Outcome
Correlation between SvO₂ and ScvO₂surrogate

Central venous oxygen saturation is a reliable surrogate for mixed venous oxygen saturation, but neither reliably reflects cardiac index.
