Estimation of pulse pressure variation and cardiac output in patients having major abdominal surgery: a comparison between a mobile application for snapshot pulse wave analysis and invasive pulse wave analysis.

abstract：:Total shoulder arthroplasty (TSA) is typically performed in the beach-chair position. Maintenance of adequate mean arterial pressure is required to provide appropriate cerebral perfusion pressure and prevent cerebral ischemia. Placement of an arterial line to facilitate invasive monitoring is discretionary, based on c...
