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

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.

Treatment and study plan

snapshots or videos of monitor

Procedure

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

Procedure

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

Primary outcomes

  1. Comparison of mobile device analysis results with Vigileo analysis results

    Time frame: 1 day

    Cardiac output and Stroke Volume Variation were acquired by mobile device and Vigileo

  2. Comparison of arterial waveform collected directly analysis results and Vigileo analysis results
