Retroperitoneal bleeding is commonly associated with blunt trauma to the abdomen. Current medical tools cannot be used for continuous monitoring of the bleeding. In the study, electrical impedance tomography (EIT) was applied to monitoring the retroperitoneal bleeding of an animal model. ⋯ In total, 20 mL of blood volume changes could be identified by EIT. The progression of the retroperitoneal bleeding can be monitored by EIT in the proposed animal model. It suggests EIT is potential as a useful tool for continuous monitoring of retroperitoneal bleeding after blunt trauma.
