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

Condition(s) studied

Investigational drug(s) / intervention(s)

snapshots or videos of monitor: The mobile device（a phone）was used to obtain the screen image of the monitor, and the arterial blood pressure waveform is extracted by image processing technology.

Pressure transducer: Arterial catheter were connected to conventional pressure transducers and Flotrac-Vigileo transducers.

Study 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.
