Erratum to: OBES SURG DOI 10.1007/s11695-007-9378-6

Subsequent to e-publication of the above Review Article (which is the preceding article), the author noted that he had made an error in the description of Eq. 8. The sentence above Eq. 8 currently reads, K is the ratio of uncalibrated pressure pulse contour-derived SV (SVUNCAL) and transpulmonary TDCO-derived SV (i.e. K = SVUNCAL/SVTD). Thus,

$$ {\text{SV}}_{{{\text{CAL}}}} = {\text{SV}}_{{{\text{UNCAL}}}} \times {\left( {\frac{{{\text{SV}}_{{{\text{UNCAL}}}} }} {{{\text{SV}}_{{{\text{TD}}}} }}} \right)} $$

The sentence and corresponding equation should read, K is the ratio of transpulmonary TDCO-derived SV and uncalibrated pressure pulse-derived SV (i.e. K = SVTD/SVUNCAL). Thus,

$$ {\text{SV}}_{{{\text{CAL}}}} = {\text{SV}}_{{{\text{UNCAL}}}} \times {\left( {\frac{{{\text{SV}}_{{{\text{TD}}}} }} {{{\text{SV}}_{{{\text{UNCAL}}}} }}} \right).} $$
