Effect of the Steep Trendelenburg Position on Respiratory Gas Heat Content

University of California, Davis10 enrolled

Overview

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.
