Brief Summary

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.
