We read with interest the recent study on central venous saturation (ScvO2) and mixed venous saturation (SvO2) in 53 patients with severe sepsis [1]. For several reasons, however, we feel the authors' broadly stated conclusion that 'a positive (ScvO2 - SvO2) value is not associated with improved outcome' is unwarranted.
