Abstract:
Cerebral and retinal perfusion monitoring devices, systems, and methods, are described. Such devices, systems, and methods can be used during surgical procedures, including cardiac surgery with cardiopulmonary bypass and spine surgery in prone position, to monitor a patient's brain perfusion in real time. In some embodiments, such monitoring allows trends in perfusion over time to be assessed. Such monitoring allows appropriate medical interventions to be undertaken in the event a state of hypoperfusion is detected, thereby reducing risks of brain hypoperfusion and stroke for patients undergoing heart surgery with cardiopulmonary bypass, as well as minimizing risk of retinal artery thrombosis with resulting blindness for patients undergoing prolonged procedures in the prone position.
