Effectiveness of Hypotension Prediction Index (HPI) in Preventing Hypotension in the Post-Anesthesia Care Unit (PACU)

HPI monitoring is performed using the Edwards Lifesciences HemoSphere platform to provide real-time hypotension prediction based on arterial pressure waveform analysis. Interventions such as fluid bolus or vasopressor are administered per protocol when HPI ≥ 85.

Standard monitoring in the post-anesthesia care unit (PACU), including non-invasive blood pressure, heart rate, and oxygen saturation measurements. No Hypotension Prediction Index (HPI) monitoring is used. Interventions are performed according to routine institutional practices.
