| Summary: | This project aims to utilize an Impulse-Radio Ultra-wideband (IR UWB) radar for a continuous and non-invasive monitoring method of blood pressure(BP).Although BP is a critical indicator of health conditions, traditional methods of measurements are restrictive and inconvenient. By leveraging the ability of the IR UWB radar to detect very subtle movements, this project aims to measure the blood pressure of the subject.
The objective of this study includes the implementation of the IR UWB radar to accurately measure heartrates at two different arterial sites to obtain the pulse transit time(PTT) and subsequently an estimation of BP through various proposed methods. Clutter removal, filters and principal component analysis are employed for signal processing with a focus on accuracy and reliability of data. Multiple BP estimate relation utilizing PTT are evaluated to determine the appropriate method for an IR UWB radar.
The results demonstrate the feasibility of using IR-UWB radar for an accessible, continuous, and non-invasive blood pressure monitoring method. Potential application of this technology includes a screening at the emergency department, remote patient monitoring and personalized healthcare interventions. Recommendations for further refinement and integration into clinical practice are discussed, highlighting the significance of this project for a non-invasive blood pressure monitoring technology |
