Objectives
Narrative objectives1
We will measure the zero flow pressure (effective downstream pressure) of the patients in sitting, prone or Trendelenburg position under general anesthesia. The aim of this study is to explore adequate blood pressure that can maintain cerebral perfusion of patients in sitting, prone or Trendelenburg position under general anesthesia.
