Auxiliary Anesthesia Technique for Extracting Advanced Hemodynamic Parameters Based on Peripheral Arterial Waveform Photography

February 20, 2025 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University
In this study, the arterial blood pressure waveform was digitized by snapshots or videos of the patient monitor to further estimate advanced hemodynamic parameters, so as to realize continuous and automatic monitoring of advanced hemodynamics on mobile devices to assist anesthesia, with a view to developing an Android/iOS application for mobile devices and application in patient management.
