A Continuous, Real-Time Coagulation State Monitor for ECMO Patients.

For patients undergoing extracorporeal membrane oxygenation (ECMO), clot formation is a critical complication requiring high-risk circuit changes. Blood tests used to assess clotting risk may be drawn only four times a day, potentially missing key information that could inform physician intervention. To mitigate these risks, we designed a device that integrates ultrasound imaging and impedance sensing for continuous, real-time monitoring of blood coagulability (the blood's likelihood to clot).
