Real-Time Blood Delivery Sensing For Critical Care and Beyond (RTBS)
This project addresses the lack of direct, real-time, non-invasive measurements of important cardiovascular data in ICU patients. CVD and cardiac surgery comprise 30% of ICU and are the leading causes of ICU admission, cost, and mortality.
All treatment tries to increase the heart’s stroke volume (SV) and the resulting perfusion of organs and peripheral tissues. The RTBS project will develop multiple lumen catheters for use with localised cardiovascular mechanics models to deliver SV in real-time. Peripheral flow, oxygen extraction and thus perfusion will be assessed using a novel pulse oximeter solution that utilises pneumatic constriction to create the first ever non-invasive simultaneous measures of arterial and venous oxygen saturations and local flow, and thus extraction and perfusion.
