Brief summary

This is a single site, prospective, non-blinded, non-randomized, non-interventional study designed to evaluate the effect of changes in patient position on the measurement of respiratory heat loss (enthalpy). This study would be carried out on patients whose operation requires the use of the steep Trendelenburg position independent of this study.
