A system for semi-automated management of blood loss during surgery: Preliminary results

This paper presents preliminary results from a pilot study for automated management of blood loss during surgery. The paper describes our approach in developing mathematical models for the cardiovascular system including blood loss and use of colloids for resuscitation. Further, adaptive models are synthesized and used for designing appropriate control algorithms. These algorithms are further integrated into a computerized platform that interfaces with medical devices such as monitors and pumps, which will be tested and validated in animal trials. The eventual development will be minimalist with an open architecture in order to enable easy adoption by others in the community.
