(1997). the lack of hemodynamic augmentation during Trendelenburg positioning in the euvolemic, normotensive patient, the same cannot be concluded for the hypotensive, shock patient.4 In the hypotensive patient we would expect that normal circulatory physiologic control mechanisms would work to amplify rather than modulate any attempts to increase CO. #FOAMed Medical Education Resources by LITFL is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
