A Prospective Observational Study of Plethysmograph Variability Index and Perfusion Index in Predicting Hypotension with Propofol Induction in Noncardiac Surgeries
CONTEXT: Propofol induction is associated with hypotension due to changes in intravascular volume, tone of vessels and cardiac output. Plethysmograph variability index (PVI) and perfusion index (PI) are derived indices from pulse oximeter, used for assessing fluid responsiveness and vessel tone, res...
