A Novel Approach for Multi-Parameter Hemodynamic Monitoring

University of Pittsburgh researchers have developed a novel method and apparatus for multi-parameter hemodynamic monitoring. This technology extends the capabilities of the standard arm cuff device, enabling accurate and convenient monitoring of blood pressure (BP), cardiac output (CO), and left ventricular ejection fraction (EF). This could significantly improve patient outcomes and reduce healthcare costs with minimal changes in clinical practice.

Description

The invention leverages smart algorithms to enhance the functionality of the ubiquitous arm cuff device. It allows for the detection of frequent hypotension, diagnosis of its cause, and titration of interventions. The technology is particularly useful in managing surgery and intensive care patients, where continuous monitoring of these three hemodynamic variables is crucial.

Applications

- Hemodynamic monitoring tool
- Surgery management
- Intensive care patient management
- Goal-directed therapy

Advantages

The technology offers several advantages over existing methods. It provides accurate measurements of BP, CO, and EF using a single, non-invasive device. The use of arterial compliance measured with the cuff device allows for more accurate CO computation. Furthermore, the technology enables the computation of EF and pulse pressure variations from a cuff pressure waveform, which may not have been proposed before.

Invention Readiness

The concept of this technology has been developed. The technology, which enhances the functionality of the ubiquitous arm cuff device through smart algorithms, is currently under review and has the potential to be implemented in the near future. It allows for the detection of frequent hypotension, diagnosis of its cause, and titration of interventions, making it particularly useful in managing surgery and intensive care patients.
