A new method of monitoring a patient’s blood in real time with a beam of light could improve patient safety during surgeries.
During heart surgery, there is a risk of the patient’s blood clotting too quickly and causing the heart-lung machine to shut down. This danger requires frequent blood tests, which in turn require that the surgery is paused.
To help reduce the need for physical blood tests, the technology created by Aristide Dogariu of the University of Central Florida uses an optical fiber to beam light through the transparent tubes of the heart-lung machine directly at the blood. The reflected light is analyzed in real time, allowing the surgery to continue without gaps.
