A Novel Method for Cardiac Output and Vascular Parameters Estimation Using Peripheral Arterial Waveforms: Integrating Windkessel Model via -parameter identification

Key Result

A novel framework integrating a four-element Windkessel model via alpha-parameter identification was internally validated against the EV1000 reference for estimating cardiac output.

Key Points

• The research aims to develop a new method for estimating cardiac output and vascular parameters using arterial waveforms.
• Utilized a four-element Windkessel model reformulated through a novel $oldsymbol{eta}$-parameter identification framework.
• Internal validation was conducted against the EV1000 pulse-contour reference system.
• The novel method showed a significant correlation with the EV1000 reference, enhancing cardiac output estimation accuracy.
• Findings indicate improvements in vascular parameter determination compared to conventional methods.
