Effect of the Steep Trendelenburg Position on Respiratory Gas Heat Content

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02153164
Recruitment Status : Completed
First Posted : June 2, 2014

University of California, Davis

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.
