"Hypotension Probability Indicator in TAVI/MitraClip for Hypotension Management"

"Hemosphere monitoring and requires the use of a AcumenIQ sensor connected to an arterial line (Edwards Lifesciences Corp., Irvine, CA, USA). The sensor has a splitter which enables the splitting of the arterial blood pressure signal to facilitate a blood pressure signal on both the anesthesia machine monitor (standard care) and the HemoSphere monitor (study).~In the intervention arm we asked the anesthesiologist and anesthesia nurse to use the study treatment flowchart. If the HPI alarm goes off, which entails both a sound and a flickering light, we ask the anesthesiologist to act upon this alarm immediately. Use of the study treatment flowchart ensures that the anesthesiologist has to think about the underlying cause. The HemoSphere with HPI software has a second screen with variables that provide information about the underlying cause of the predicted hypotension."
