Abstract：Objective To explore the feasibility of EIT-based (Electrical Impedance Tomography) real-time monitoring of the little pig pulmonary hemorrhage model. Methods As the objective of this study, electrical impedance changes of little pig pulmonary hemorrhage model was constantly and real-timely monitored with adoption of EIT. Results Gradual increase of each 5 mL of injected blood volume resulted in redness displayed in EIT images incorresponding areas and gradual enhancement. The hemorrhage locations revealed by EIT accorded with those displayed by CT. Quantitative analysis results indicated that gradual increase of each 5 mL of injected blood volume leaded togradually-enlarge delectrical impedance and area in the relevant locations in EIT images, which proved the relevance between EIT quantitative analysis indicators and the injected blood volume. Conclusion EIT could real-timely monitor the electrical impedance changes caused by pulmonary hemorrhage in little pigs in an effective way, which laid a solid foundation for clinical researches.
